subject:"\[Freedos\-user\] How to"

That did it! "ã" and other tilde-accentuated characters are displaying
perfectly now. Thanks!

Although I cannot say I understand the fix, it did work and now all
tilde-accentuated characters work fine everywhere in FreeDOS.

I had to change "fdos" to "freedos" since that is how the directory is
actually called on this version.  I added the fix to FDAUTO.BAT, which I
assume is FreeDOS version of AUTOEXEC.BAT.

LH DISPLAY CON=(EGA,,1)
> MODE CON CP PREP=((858) C:\FREEDOS\cpi\EGA.CPX)
> MODE CON CP SEL=858


Is that an okay place to put those settings?

Thanks!

Re: [Freedos-user] How can I make FreeDOS correctly display the "ã" character?

Unfortunately, after entering the following:

display con=(ega,850,1)

mode con cp prep=((850) C:\freedos\cpi\ega.cpx)


There was no alteration in the displaying of "ã".

I tried the commands. "MODE CON CP SELECT=858" and "MODE CON CP

Re: [Freedos-user] How can I make FreeDOS correctly display the "ã" character?

1. I enter "ã" by typing the "~ ^" followed by the "a" key. Resulting in
"ã".
2. Yes, it is a separate key on my keyboard. By itself, that key will
generate the tilde. With shift, it generates the "little hat" (circumflex),
which is used in words such as "ângulo" or "acadêmico". The circumflex
displays perfectly on FreeDOS, the tilde ("~") does not.
3. "keycode" generates "Bad command or filename". I'm not sure how to
install this command, I'm looking at fdimples and it is not immediately
obvious :/. Is there a way to get it installed I am not aware of?

Thanks!

Re: [Freedos-user] How can I make FreeDOS correctly display the "ã" character?

2024-04-25 Thread Frantisek Rysanek via Freedos-user

Let me suggest the following hypothesis:

Your FreeDOS and graphical hardware is running with the HW-default 
code page, known as Code Page 437.
https://en.wikipedia.org/wiki/Code_page_437

Whereas, you're trying to display text encoded in CP850.
https://en.wikipedia.org/wiki/Code_page_850
CP850, aka PC Latin 1, which is not the same as ISO Latin 1.

Perhaps your keyboard is already switched to produce CP850.

You probably need to run some program(s) to load the right codepage 
into the graphics card. I don't have a ready-made and tested recipe 
for you... could be something like:

In config.sys:
COUNTRY=055,850,C:\FDOS\BIN\COUNTRY.SYS

In autoexec.bat:
DISPLAY CON=(EGA,850,2)
MODE CON CP PREP=(437,850) C:\FDOS\BIN\EGA.CPX)
MODE CON CP SEL=850
   maybe also:
CHCP 850

That's what I was going to suggest too. Looks like Brazilian
Portuguese is codepage 850? So I think Davi also needs to enter these
commands to set up the display for 850:

display con=(ega,850,1)
mode con cp prep=((850) C:\freedos\cpi\ega.cpx)

Hi Robert and Davi,


The system's keyboard and layout are already configured to "br" (for
Brazilian Portuguese) and working perfectly. Other accentuated
characters display just fine. That is the case of "á", "à", "ô".
However, "ã" shows as something else entirely. Image below:
oIh6TW8.png

How can I get FreeDOS to correctly display those characters?


You probably have to load DISPLAY and use MODE to set the codepage
to load a font which has all accented characters at the place where
your already Brazilian keyboard configuration expects them :-)

See the HTMLHELP system for details. There should also be some
examples on the web. It should work similar to this:

First, load the DISPLAY thing. You can do this in your autoexec
to load it automatically at boot, or manually at the prompt:

LH DISPLAY CON=(EGA,,1)
rem or maybe for example DISPLAY CON=(EGA,858,1) or similar?

Second, use MODE CON CODEPAGE (shorthand MODE CON CP also
works) to first prepare (shorthand PREP) and then select
(shorthand SEL) the codepage for your country.

In my example the codepage is 858, which happens to be in
EGA.CPX, which is a compressed version of EGA.CPI - some
less common codepages will probably be in other CPX files.

MODE CON CP PREP=((858) C:\FDOS\cpi\EGA.CPX)

MODE CON CP SEL=858

You can do those two MODE invocations in autoexec or at
the prompt as well. You can use MODE /? for help, too.

The internet says that Brazilians prefer codepage 860 :-)

Your codepage is probably set to CP437, which does not contain the "ã"
character. Change your codepage to CP850 (or CP858 if you also need the

Re: [Freedos-user] How to try FDT2404 (Latest test version) on QEMU the hard way + kvm fixed

2024-04-05 Thread Paul Dufresne via Freedos-user

It turn out that using kvm was giving me the illusion of using kvm... but I 
missed the warning saying
that kvm was not loaded, and that it was falling back on tcg  don't know 
really what it is.
The reason was that "Intel virtualization technology" option in "BIOS" was 
disabled.
After enabling it, now qemu-system-i386 -enable-kvm works... I hope for real.
So qemu-system-i386 -enable-kvm make it more obvious that you need to fix 
something than by using kvm.

Also... it seems that setup need the cdrom (dvd) to be working... as it seems 
to install from it.

My guess was that because I was using -machine pc-i440fx-4.2 I was forcing the 
use of cdrom...
Somehow, the cdrom drive was empty, but setup was finding the emulated hard 
disk containing the content of the cdrom...
and used that instead of the cdrom... at least this is my hypothesis why it 
worked, and not anymore now that I don't use -macine.

So now I come back to use 
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/FDT2404-LiveCD.zip
instead of 
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/FDT2404-FullUSB.zip

I installed with (admittedly more complex than needed):

qemu-system-i386 -enable-kvm -m 32 -cpu 486 -device 
ide-hd,drive=myhd,bootindex=2 -drive 
file=2404.qcow2,format=qcow2,if=none,id=myhd,media=disk -device 
ide-cd,drive=mydvd,bootindex=1 -drive 
file=T2404LIVE.iso,format=raw,id=mydvd,if=none,media=cdrom 

And as this use a menu to choose what to boot with, there is no real need to 
exchange bootindex values.

But to have sound and networking, I just used (added previous message 
parameters to previous line):
qemu-system-i386 -enable-kvm -m 32 -cpu 486 -device 
ide-hd,drive=myhd,bootindex=2 -drive 
file=2404.qcow2,format=qcow2,if=none,id=myhd,media=disk -device 
ide-cd,drive=mydvd,bootindex=1 -drive 
file=T2404LIVE.iso,format=raw,id=mydvd,if=none,media=cdrom -audiodev 
pa,id=mysnd -device sb16,audiodev=mysnd -device adlib,audiodev=mysnd -machine 
pcspk-audiodev=mysnd -vga cirrus -display sdl -net nic,model=pcnet -net user

You can get control back from emulated machine with Ctrl-Alt-G (as shown in 
upper window) and allows you to close the window.

Hope it can help someone while not confusing too many!

I use qcow2 because it's a bit more efficient, and a little faster.
(Not that speed matters much here .. my 3-yr old desktop PC is still
*way* more powerful than a 1990s '486 or Pentium PC.)

I use guestfstools to "mount" the virtual disk from Linux. Works
great. It's basically this:

guestmount -a "$img" -m /dev/sda1 "$mnt"

In other words:

mkdir /tmp/freedos
guestmount -a mystuff.qcow2 -m /dev/sda1 /tmp/freedos

..and that will "mount" the first (only) partition in my virtual disk,
and make it accessible at /tmp/freedos.

That's a lot. FreeDOS (like any DOS) is not big. What are you putting
in that virtual disk? My "C:" virtual disk is 500MB, and that's much
larger than I need to install OpenWatcom plus editors and tools. My
"D:" virtual disk is like 200MB.

But I realize that I could use the USB key image on an emulated USB key:

So, I guess this tend to suggest the follwing approach for most people: (almost 
obvious, but was not really told to me before)

Have C: be the target hard disk, have D: be the installation disk...

on installation, boot D:  , do a minimal installation, then on usage boot C: 
but with D: present, 
do fdimples D: to add needed packages.

People that need packages only present on Bonus disk should add the E: drive 
with the Bonus image, and use
fdimples e:
to add packages from the bonus disk.

I was prefering raw, because I was using:
https://www.seei.biz/how-to-mount-raw-images-img-images-on-linux/
to mount raw disk, and exchange data between the host and the emulated machine.

But I discovered qemu-nbd... that allows the same with qcow2 image too.
So I guess I will adopt qcow2.
Now, as I understand, the size of the file for qcow2, is way less than the size 
specified...
because allocation is done only when needed... so I would suggest to oversize 
the value...
maybe 3G?

On Ubuntu 23.10, with QEMU 
paul@starman:~/FDT2404$ kvm -enable-kvm -m 32 -hda T2404FULL.img
WARNING: Image format was not specified for 'T2404FULL.img' and probing guessed 
raw.
 Automatically detecting the format is dangerous for raw images, write 
operations on block 0 will be restricted.
 Specify the 'raw' format explicitly to remove the restrictions.
Could not access KVM kernel module: No such file or directory
kvm: failed to initialize kvm: No such file or directory

but the following works:
kvm -m 32 -hda T2404FULL.img

paul@starman:~/FDT2404$ qemu-system-i386 --version
QEMU emulator version 8.0.4 (Debian 1:8.0.4+dfsg-1ubuntu3.23.10.3)
Copyright (c) 2003-2022 Fabrice Bellard and the QEMU Project developers

https://www.qemu.org/docs/master/system/invocation.html
says: "Older options like -hda are essentially macros which expand into -drive 
options for various drive interfaces. The original forms bake in a lot of 
assumptions from the days when QEMU was emulating a legacy PC, they are not 
recommended for modern configurations."

 > $ qemu-system-i386 -enable-kvm -m 32 -cdrom T2404LIVE.iso -hda
 > 2404.qcow2 -boot order=d
This works with iso file, and d means to boot cdrom... but this means d cannot 
be used to boot with second hard drive ... which is needed when I
choose to use FullUSB image. So I tend to prefer the "new way":

"Instead of -hda, -hdb, -hdc, -hdd, you can use:
qemu-system-x86_64 -drive file=file,index=0,media=disk
qemu-system-x86_64 -drive file=file,index=1,media=disk
qemu-system-x86_64 -drive file=file,index=2,media=disk
qemu-system-x86_64 -drive file=file,index=3,media=disk "

"qemu-system-x86_64 -drive if=ide,index=1,media=cdrom"

"index=index
This option defines where the drive is connected by using an index in the 
list of available connectors of a given interface type.
 compare with bootindex=index later in this message.

media=media
This option defines the type of the media: disk or cdrom."

So rather than -boot order=d I would prefer to use:
https://www.qemu.org/docs/master/system/bootindex.html

I was saying than rather to use mount -o loop,offset= line to mount RAW images, 
it is probably better to use:
https://gist.github.com/shamil/62935d9b456a6f9877b5
that works with qcow2.
That was not working on VanillaOS... but seems to work on Ubuntu 23.10.
(bit unclear when you need to use sudo on these lines)...
https://www.baeldung.com/linux/mount-qcow2-image might be clearer.

So... I was using the same arguments you use... but try to change to more 
modern parameters, because of deprecation warnings/messages.

Re: [Freedos-user] How to try FDT2404 (Latest test version) on QEMU

2024-04-05 Thread Jerome Shidel via Freedos-user

Hi Paul,

Just a side note about installing using the FullUSB.

One of my DOS test machines is an Acer One netbook with a 1Ghz Atom processor 
and an ancient 30Gb SSD. This machine has no CD/DVD drive. It does boot from 
the FullUSB when written to a flash drive. It takes about 5 minutes from start 
to finish (boot, partition, reboot, install, reboot) to do a Full install 
without sources. 

That machine will also boot from a USB floppy drive. 

Another side note…

You could create a second partition on the USB stick and copy the files from 
the Bonus CD to to that.

Although it can only use one at a time, modern versions of FDIMPLES can use 
different local package repositories. 

You could have different repos on different drives. Or, even multiple ones on 
the same drive in different paths.

When FDIMPLES starts, it checks the current drive for a repository in one of 
the standard paths. If it does not find one, it searches existing drives C: 
through Z: for a repository. 

You can also tell it to check a specific drive (and/or alternate path) for a 
repo at startup. 

For example,

C:\>fdimples e:
C:\>fdimples d:\repo-1

etc.  

:-)

Re: [Freedos-user] How to try FDT2404 (Latest test version) on QEMU

2024-04-05 Thread Jim Hall via Freedos-user

I run FreeDOS in QEMU on Linux, so I can show you what I do.

First, I unzip the LiveCD ISO image so I can use it:

$ unzip FDT2404-LiveCD.zip '*.iso'
Archive:  FDT2404-LiveCD.zip
  inflating: T2404LIVE.iso


Then I create a virtual disk where I can install FreeDOS T2404. I'll
set this up as 500MB, which is plenty big for what I do:

$ qemu-img create -f qcow2 2404.qcow2 500M
Formatting '2404.qcow2', fmt=qcow2 cluster_size=65536 extended_l2=off
compression_type=zlib size=524288000 lazy_refcounts=off
refcount_bits=16


And then I boot the FreeDOS 1.3 LiveCD using QEMU. To install, I don't
need much, so I set up FreeDOS to use 32MB memory. I use -enable-kvm
with QEMU 8.1.3 on Fedora Linux 39.

$ qemu-system-i386 -enable-kvm -m 32 -cdrom T2404LIVE.iso -hda
2404.qcow2 -boot order=d


That gets me into the installer, which will always boot from the
LiveCD because I used order=d. Install FreeDOS as you would normally.

After I install, I use a slightly different command line to boot
FreeDOS. This gives me two things: 1. I have a separate hard disk
image with all my personal stuff, and 2. I add SB16 and AdLib support
so I can play games. This is the script I use to run FreeDOS: (quoted
with ">")

A note on the paths: I keep my FreeDOS install (my virtual C: drive)
in /usr/local/tmp because I don't need to back it up. If it's outside
my home directory, I don't bother backing it up when I backup my
computer. (I can just download it again and re-install it.) But I have
my personal stuff under my home directory (in $HOME/lib/freedos) so
that gets backed up.

Also: this shows that I have the BonusCD loaded on the virtual system.
After I install, the first thing I do is switch to the BonusCD so I
can install the compilers and editors I use.

[Freedos-user] How to try FDT2404 (Latest test version) on QEMU

2024-04-04 Thread Paul Dufresne via Freedos-user

Hi! Especially to Lunduke fans having their "second part" of DOS week... about
one year and a half after first part.
So from April 3 to April 10 2024.
I am not a paid subscriber to lunduke.locals.com and just observing it from far.

I decided to retry FreeDOS after not using it for too many months.

And as I do in this time... I search back the messages I have previously left
on the list to help me know how to launch qemu...
as I don't think the wiki have an article about it...
But it has been a long time... and I am seeding a new message for the next
time(s).

So FDT2404 is out: "
###
FreeDOS 2404-Test ("FreeDOS T2404")
###

Warning: This is a FreeDOS development build and is for testing purposes.
It may exhibit behavior vary different from a release build and may not be
suitable for regular use. For general use, please consider using the latest
release build available at http://freedos.org
"

And can be found at:
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/readme.txt

This time, I have chosen to use
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/FDT2404-FullUSB.zip
rather than the usual
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/FDT2404-LiveCD.zip
Mostly, I find a disk image, a more simple and logical format that a CDROM or
DVD image format (iso file).

So with an iso file I would use -cdrom image.iso... but the FullUSB.zip
contains an .img file, that I will use the same
qemu parameter as the hard drive destination image: -drive
format=raw,file=$DISK where DISK=T2404FULL.img

Steps goes about like this:
Download and extract
https://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/test/FDT2404-FullUSB.zip
in FDT2404 directory.
cd FDT2404
qemu-img create fdos.img 1000M
DESTDISK=fdos.img
INSTALLDISK=FDT2404FULL.img

At install time, I present first INSTALLDISK, then DESTDISK:
qemu-system-i386 -cpu 486 -name FreeDOS -machine pc-i440fx-4.2 -m 64 -drive
format=raw,file=$INSTALLDISK -drive format=raw,file=$DESTDISK -audiodev
pa,id=mysnd -device sb16,audiodev=mysnd -device adlib,audiodev=mysnd -machine
pcspk-audiodev=mysnd -vga cirrus -display sdl -net nic,model=pcnet -net user

After installation, I present first DESTDISK containing the installed FreeDOS,
and then INSTALLDISK (not so much needed anymore):
qemu-system-i386 -cpu 486 -name FreeDOS -machine pc-i440fx-4.2 -m 64 -drive
format=raw,file=$DESTDISK -drive format=raw,file=$INSTALLDISK -audiodev
pa,id=mysnd -device sb16,audiodev=mysnd -device adlib,audiodev=mysnd -machine
pcspk-audiodev=mysnd -vga cirrus -display sdl -net nic,model=pcnet -net user

Information given at boot seems to say E: is the INSTALLDISK... but it is
really D: ... I don't know why.

Games seems to work often better than it did in my memory.
Was it on VirtualBox that color palette was wrong?

Also... Magic Mirror game seems to start... and I did not remember to have seen
it working before.

For me DHCP seems not really working... but I run this on Vanilla OS ... with
apx run $command and so I think maybe it does not work because the virtual
machine
is running inside the Ubuntu sub-machine (an other virtual machine as far as I
know).

So it seems to be the gist of what I wanted to say.

[Freedos-user] How To Install FreeDOS 1.3 To a Huge SD Card Without the Need of Another Installation Drive-Manual Installation Without Using the Installer.

Title: Webpage not available

  
  Greetings,I needed to do,what is in the following howto,so I just tested this method as working & consulted with Mr.Hall,who advised to share my experience & howto based on it with the rest of the FreeDOS community,so for the other users I will recapitulate the steps for custom installation of FreeDOS 1.3 to a huge SD card:0.)U must love DOS.1.)Download images of FreeDOS 1.3 & extract files(by any program,which can access files within ISO/IMG),U wish to implement into Your custom installation or download particular files separately from FreeDOS.org .1.5)Download Rufus,if U already not have it.2.)Insert the target SD card & open Rufus.3.)Select the target SD card in Rufus,select to make it bootable by its INTEGRATED FreeDOS image by a checkbox named FreeDOS(do not use none of external IMG/ISO files,but Rufus' internal FreeDOS),select the smallest cluster size,it allows(for 512GB drive it is 8KB,for 1TB drive it is 16KB,for larger it is 32KB) & start formatting.3.5)If U r doing so with 1TB or 2TB drive,now is a good time to go to toilet or make yourself a coffee(in case of the latter I encourage U to use soy milk,not the real 1 to save the environment & not torture the Cows;if U r like Capt.Janeway & U will make Yourself Coffee,Black,Cows r safe already)‎.4.)Now U have a bootable FreeDOS SD card with some older version of FreeDOS,upgrade it to FreeDOS 1.3 by opening Total Commander(or similar file manager),in which in 1 panel open the target drive & in the other panel find the downloaded files of FreeDOS 1.3,select system files(Command.com ,Kernel.sys ) of FreeDOS 1.3 & copy these over those older,Rufus placed to the target drive(do not skip the part with Rufus,otherwise the files would not be in 1st sectors & would not boot).Now U will have the minimal FreeDOS 1.3 installation on Your target drive.5.)Reboot to the target drive to test its bootability,if OK,reboot back to the OS,where U r preparing the installation,now U have done the system part(the hard 1) & the rest is so easy,U may do it half-asleep(if Your coffee withstood to this point,U do not need to make Yourself another).6.)In Total Commander(or so) just unpack all archives,U downloaded,to particular folders of Your target drive.7.)Edit Config.sys & Autoexec.bat to ensure,the lines for drivers,mainly for Himemx.exe ,match the paths,U had placed them after unpacking/decompressing.8.)Edit Autoexec.bat to let it load Your favorite file manager or GUI after boot.9.)Reboot to Your new FreeDOS 1.3 drive & enjoy(for example by trying some games).So this U can place to a section with HowTos or so,it is just tested & worx.I hope,this will help those,who wish to install FreeDOS 1.3 to a huge SD card directly,skipping the installation media creation,or this may be useful for those,who wish to maximally customize Your installation process,partitioning,setting cluster size,etc.,if the target drive is HDD,U have already done standard installers,but this is mainly for the case,the target media is some kind of removable storage,bigger,than the image FullUSB,as U probably need to have Your big SD/CF/...card/flash drive single-partitioned to have it fully accessible also from Windows older than 10(i guess,none of us here likes Win.10) & @ the same time fully accessible to the FreeDOS installed on the card,so U will get the newest LIVE FreeDOS bootable drive,which U can move between various PCs,boot it anywhere & also access it from other OSes fully & have set the best cluster size,etc.,U may also upgrade older FreeDOS installation,or just use it to make the directory structure Your own way instead of the way preset by installer,I hope,this can be used many ways for many purposes,all purposes,for which the precompiled standard installation ISOs/IMGs r not right the Your desired method for a particular goal,U need.If U find this useful,enjoy.If U find it irrelevant,let it be for others.With best regards for all the FreeDOS community Sabina Zelená[=Green].Live long & prosper.Shabbat Shalom.Sent from BlackBerry Key 1's Hub,which has some bugs caused by EoL of BlackBerry services,but same as DOS,I will not give up BlackBerry...I just love real keyboards.___

Hi!

Assuming that you just want to have MORE text on your screen,
without actually wanting to use graphics mode, you can select
quite a few modes with MODE CON or with various VESA tools.

For example in dosemu2, the following works just fine:

MODE con cols=132 lines=60

This will search for 132x60 character VESA mode and use it.

In dosemu2, VESA text modes 80x60, 132x25, 132x43 and 132x60
are available, but others can be available on other graphics
cards or in other emulators or virtual computers, dosbox,
bochs, qemu, vmware, and so on.

For non-VESA modes, you can for example use:

MODE con co80,50

That will select a VGA compatible 80x50 text mode.

Sometimes MODE will get modes wrong depending on from
which mode to which you transition. For example it may
end up in 80 column modes when asking for 132 columns,
depending on how many lines you want and had before.

It helps to experiment: Often, you can help mode to get
into the desired mode by first selecting a similar, easier
mode, so it can find out how more easily to go further.

For modes with more than 132 columns, you need VESA tools
which make fewer assumpions about things than MODE does.

There seems to be a general misunderstanding that DOS only supports

other text resolutions. Through the use of special text mode fonts, 
most VGA cards could even support different font heights producing 
very unusual display resolutions such as 80x20, 80x16, 40x22, etc. 
Therefore it was always a bad idea to hard code support for a single 
display resolution into software. 


Sorry, Jerome, but that is all beside the point. The OP is not trying a 
different text resolution, but is trying to force a graphics mode, which 
will NEVER work with any basic DOS text mode program.


Yes, it is possible, at least on legacy hardware, to get text 
resolutions other than 80x25 and 40x25 (as well as 80x43 on an EGA  
adapter and 80x50 on a VGA adapter), but those are HIGHLY legacy 
hardware depended, as they rely on directly manipulating the VGA 
adapters sync registers.
I used to write and use a tool myself that could generate up to 132x60 
character text screens, on the right VGA hardware.
HOWEVER, on a lot of newer video card/chips, this direct manipulation 
doesn't work anymore, as those newer chips simply do not support the 
sync of the video signal in the same way as undocumented ways of the 
original VGA adapters allowed. On some, you will actually damage the 
hardware, as you are generating out of bounds frequencies, on some, 
simply nothing will happen, either no change or simply a turning of the 
video signal, resulting in a black screen, from which only a cold boot 
and subsequent re-initialization of the video hardware will recover from.
It will also no work on a lot of LCD/LED screens, which do no sync the 
video signal like old CRT monitors did.

I have a copy of a very handy program from the early 1990s called
Laptop UltraView.

It was designed for laptops in the era when they had VGA
passive-matrix LCDs: 648*480 in maybe 16 colours -- sometimes 256 if
you were lucky.

VGA text mode is, I think, 640*400.

LT/UV reset the DOS console into 640*480 and told DOS it was 80*25
mode, and could redefine the fonts in software. It then quit: it was
not resident, so took no RAM. The result was bolder clearer text that
was easier to read.

It also defined a bunch of soft "text" screen modes, so you could tell
DOS it had a 100x30 console, or anything that fit neatly into VGA
graphics mode. Some very hi-res "text" modes with small characters
were possible. My ZX Spectrum could just about display 64 columns of
text in its 256*192 pixels, in a 4x8 character font. VGA can do about
160x50 text in that sort of resolution, but it is not good for your
eyes.

AIR LT/UV did not understand any VESA modes so it can't use 800*600 or
1024*768 at all. Pity.

Sadly my copy is in another country right now. I can't upload it
anywhere. But it was possible, and it was a very small simple program
-- IIRC it shipped on one 720 kB floppy. It would probably be quite
easy to clone and reimplement.

Generally even with text support by the BIOS in graphics mode, they do not work 
well for the command line prompt. 

Often, there is a lack of text cursor, no scroll support or just very slow

Yep. 

9x16 VGA font, 720x400. However, that 9th bit is just a little bit odd (puns

8x16 VGA font 640x400. 

It’s been a while. But if I recall correctly, I think there were some VGA

BIOS text output functions still work in most graphic modes, hence 
having a DOS shell running in graphic mode is nothing unusual. Of course 
problems may arise for text applications that make assumptions about the

2023-08-06 Thread Jerome Shidel via Freedos-user

First…

There seems to be a general misunderstanding that DOS only supports 80x25
columns. While it is possible that an extremely lazy programmer would hard code
for that resolution, most did not. Even back in the early days the display
could be in 40x25, 80x43, 80x50 and numerous other text resolutions. Through
the use of special text mode fonts, most VGA cards could even support different
font heights producing very unusual display resolutions such as 80x20, 80x16,
40x22, etc. Therefore it was always a bad idea to hard code support for a
single display resolution into software.

Overall, the operating system software provided with FreeDOS, MS-DOS and the
others work fine in all text mode resolution as long as they have BIOS support.
As for other none-base software, you may have mixed results. It just depends
on skill of the programmer and how much effort they put into that aspect of
their software.

The real issue lays with BIOS support of text modes over 80 columns.

Back in the 386/486 days, many cards supported “high resolution” graphics
modes. Since DOS was still a primary market for such cards, many vendors
included support for higher resolution text modes in the BIOS (like 132x43).
Those higher resolution modes generally worked fine under DOS.

As Windows and graphical desktops in general became popular, the card
manufacturers changed their focus away from text mode. With each iteration,
fewer and fewer cards included support for high resolution text modes in the
BIOS.

The newer the video card, the less likely it is to support text modes with over
80 columns. Out of the older hardware I have laying around, my 486 has the most
text modes and PentiumPro only has a few extras. But, all the newer stuff
doesn’t have any. Sure they have way more graphics modes, but none of the newer
stuff includes any high resolution text modes.

If you want to see what text video modes are supported by your hardware, try
LISTVESA. As the name suggests, it will show all the VESA modes supported by
the card.

http://ibiblio.org/pub/micro/pc-stuff/freedos/files/repositories/latest/pkg-html/listvesa.html

Although VESA is the generally the standard way to discover such modes in DOS,
some vendors were known to provide access to additional modes using the
standard BIOS mode change function. Those can be problematic to discover.

For example, DOSBox has a couple such modes. It provides a 132x25 as mode 0x55
(I think) and mode 132x43 as mode 0x54 (I think).

A tool to easily change to those standard, additional or VESA modes is the
VMODE utility. It is part of V8Power Tools. However, earlier versions did not
support those additional modes that were non-standard (like 0x55). So, make
sure you have the latest version of V8Power Tools. The newest version can
switch to standard, additional and VESA modes.

Because you don't pay attention to the replies you get.

DOS is using *text *mode, you just can't select a*graphics *mode and 
expect to get text output in that mode. *Text* mode and *graphics* mode 
are, as far as DOS and most DOS based applications are concerned, two 
_mutually exclusive modes of operation_.

That is weird, here I get a dos prompt and can use DOS in the new
resolution :/

[Freedos-user] How do I change screen resolution?

2023-08-06 Thread Jose Senna via Freedos-user

 If this is of any help, you can set an
80x28 resolution in VGA by selecting
an 8x14 pixel font, instead of the more
common 8x16. Some even look better.
 It is also possible to set the screen
mode to an SVGA or higher resolution,
but not all modes support BIOS text
functions, and you need these for DOS
output. What will work depends on the
video card.

For those who haven't seen them before, attached are the video config files used
by Borland's Paradox for DOS and Quattro Pro for DOS. The actually produce the
mode menuitems found in the apps, besides their use for setting selected modes.
These were modified by me decades ago, first to better facilitate use of Tseng
proprietary 132 column SVGA text modes, and later ATI's. With Tseng I was 
usually
using 132x30. With ATI I switched to 132x43. I'm still using both apps mostly
using the DOS built into OS/2, and Radeon X600 PCIe GPU on a Core2Duo E6400, but
every now & then checking to see if PC DOS 2000 still boots and runs them.

IIRC, I never found a way to get any SVGA text modes to work with any Intel or
NVidia GPU. I don't think I even tried with NVidia.

Re: [Freedos-user] How do I change screen resolution?

Hello there,

 

So there is no way to change to VGA resolution? That is unfortunate. But thanks for telling me!
I wanted to change the resolution as a part of my desktop "customization", but I guess that will not be possible.
Thanks for all the help!

Re: [Freedos-user] How do I change screen resolution?

2023-08-06 Thread Frantisek Rysanek via Freedos-user

Hi there,

nice to see that you're trying to tweak old software to fit on modern 
screens... still I have a cold shower for you :-) Sorry about it.

Not sure where DOS borrowed its "terminal" / console code, whether 
CP/M or UNIX... the fact is, that in the way of "support", the DOS 
console lacks quite a bit of flexibility, compared to modern terminal 
emulators running in the windowing GUI. Namely, DOS doesn't seem to 
support or understand an arbitrary number of rows or columns. As 
others have pointed out, the choice is quite limited:

https://gitlab.com/FreeDOS/base/mode/-/blob/master/SOURCE/MODE/MODECON
.C?ref_type=heads#L266

https://gitlab.com/FreeDOS/base/mode/-/blob/master/SOURCE/MODE/MODECON
.C?ref_type=heads#L151

http://wiki.freedos.org/wiki/index.php/Mode

So much for support on part of DOS, which practically means the 
command line itself, plus maybe some apps that rely on DOS for the 
console display (which ones are those?)

A part of the problem is, that most software for DOS handles the 
video resolution and video output itself, directly with the hardware, 
typically using the VGA+VESA BIOS services to configure a resolution 
(if more than the classic 80x25 text mode is supported by the app).

Some software understands 43 or 50 rows too - various Borland 
TurboVision TUI's and some file managers, if memory serves.
But, that's about it.

The source code to FreeDOS "mode" command speaks even about 60 rows 
text mode support, which is interesting. Some 2 decades ago, I 
sometimes used that in Linux at the text-mode console.
Type vga=ask at the kernel command line, etc.

The other key aspect is, that without detailed knowledge of your 
proprietary video hardware, you likely need to select one of the 
graphics modes offered by the VESA BIOS services. On graphical cards 
of the general "SuperVGA category", i.e. more modern derivatives of 
the legacy original VGA, the VESA BIOS typically offers a plethora of 
high-res graphical modes (addressed per pixel) and also some text 
modes, addressed by the character. There was also a resident 
extension called UNIVBE, which could add support for some modes on 
some popular hardware that shipped with a shoddy VESA option ROM.

And this selection of VESA BIOS modes, is exactly what you get 
offered by the Linux "vga=ask", and what you can use in DOS, if your 
software supports the higher VESA VBE modes.

To get a listing of available VESA modes in DOS, I recall a tool 
called VESATEST. Or was it VTEST ? Possibly this one:
https://archive.org/details/msdos_VESA24_2_shareware
Apparently that was written in 1993.

Also my friend Rayer has written something:
http://rayer.g6.cz/programm/programe.htm#VESATEST
The current version is from 2018...

If the VTEST shows you a text mode with 60 rows and about 132 
characters, you can try supplying that one to "MODE CON COLS= 
LINES=".
But it will only work in the pure DOS prompt.
As already mentioned, various apps will mostly not respect this 
setting, and will set the video mode based on their own respective 
historical preference.

I've just stumbled over a page that points to various 
VESA/VBE-related proggies for DOS:
https://dosdriver.de/graph.php

You may also find or write some tool to ask the BIOS for just any 
supported VESA mode, including graphical, and exit to DOS without 
switching the mode back to 80x25. Sometimes you'd end up in this 
state after a game has crashed gracefully enough to return.
You can see the command.com working, characters do get displayed, the 
graphical modes often do support the BIOS text-mode output routines 
too - but the cursor probably won't blink, you may still be limited 
to 80x25 text-mode characters, and there are possibly other 
downsides, including the risk of a sudden freeze.
Also, the DOS console code is not aware of the actual resolution of 
the screen, and keeps running in 80x25 characters (or whatever it was 
before).

Times they are a changin'. While a character terminal with an 8x8 or 
8x14 font size on a full HD display may look like punk to us 
greybeards, the same font size on a 4k display is clearly a case of 
"why bother".
Technically no problem in Linux, and yes I have tried.

Frank

But this is just a special case of the MODE command, which can already set

There seem to be a serious misconception on your end. FreeDOS, like any 
DOS, works only in text mode, so you can't just select any graphics mode 
on the console. The text modes "look" is determined by the characters 
set in the BIOS of the modes available, which in short, would be 80x25 
on a monochrome (Hercules) adapter (MODE MONO) and both in 
monochrome/"black" with 80x25 and 40x25 for ANY color adapter 
(CO40/CO80, BW40/BW80).


You can NOT select any graphics resolution (like the VGA 640x480) on the 
console/command prompt. DOS is by all means text based and any graphics 
mode would be set by a DOS application only, including but not limited 
to GUIs like GEM or Windows (1.x, 2.x, 3.x) but it is those applications 
responsibility to handle drivers, resolutions and selected fonts...

What version of Curl was the original user using again?

IIRC, the official Curl website points to Michael Kostylev's
(frequently-updated) builds.

* https://curl.se/download.html  (Curl 8.2.1)
* http://mik.dyndns.pro/dos-stuff/   (DJGPP builds of Curl 8.1.2)

So obviously they should try the latest build (for DOS).

Re: [Freedos-user] How do I update certificates in FreeDOS?

And yet here we are talking about UNIX utilities ported to a 32-bit
compiler running on a 16 bit patch to an 8 bit operating system originally
coded for a 4 bit microprocessor, originally written by a 2 bit company,
that can't stand 1 bit of competition.

I daily drive Fedora Linux myself.  But curling DOS software zip files on
it is not as useful as doing that directly on 386 Dell I have sitting 3
feet away when I want to run a bit of new software on it.

Well, he stated that an attempt to use http instead failed, so I 
wouldn't have expected that any fallback in curl or wget would succeed.


This is why the proxy support is a better solution today.  The system 
hosting the proxy can be newer and support the newest security 
standards for older systems.


Again, why not use that host that you would use for that proxy for 
whatever curl/wget transfer you want to do? It seems to be always as a 
rather futile endeavor to force something like this onto (Free)DOS when 
this is pretty much a non-issue with any more modern, Internet-aware, 
operating system. And yes, doing this through a 3rd party proxy is 
certainly a less than secure and thus preferred option...

Re: [Freedos-user] How do I update certificates in FreeDOS?

https://linux.die.net/man/1/curl

-k/--insecure(SSL) This option explicitly allows curl to perform "insecure"
SSL connections and transfers. All SSL connections are attempted to be made
secure by using the CA certificate bundle installed by default. This makes
all connections considered "insecure" fail unless *-k/--insecure* is used.

In short, curl will still make encrypted SSL/TLS connections at supported
protocol versions (some servers and companies will still fall back to
earlier standards).  The encrypted/decrypted communication is considered
insecure because the trust portion of the protocol is bypassed.

And yes Ralf, if the servers or companies have strict security standards
requiring newer protocol versions, then curl will fail or will eventually
fail to communicate with them.

This is why the proxy support is a better solution today.  The system
hosting the proxy can be newer and support the newest security standards
for older systems.

FreeDOS knows jacksh@t about any certificate.

And rather than a certificate issue, it is much rather an issue about the encryption protocols and associated key length in general that prevent you from using https connections in recent years. This is totally an issue of the applications you are using, making sure that they would be able to at least support TLS 1.2, or newer...

Re: [Freedos-user] How do I update certificates in FreeDOS?

You might also try standing up an http to https proxy.  There are some
proxies setup specifically for retro computers like

https://protoweb.org/get-started/
https://github.com/DrKylstein/retro-proxy
https://youtu.be/-Qs3LVPmLgk
https://protoweb.org/wiki/servers/
http://www.steptail.com/retroweb:servers


curl let’s you specify a proxy server with “-x” and a “username:password”
(some proxies require this) with “-U”.  Examine curl’s arguments with “-h”.


Don’t do anything that requires security (banking, personal info,
connecting to work) if you decide to use a 3rd party proxy.  All of these
proxies can potentially see your credentials and sensitive information.  It
would be best to stand up your own proxy if your technically capable of
doing so.

Use a properly Internet enabled operating system.

Yes, I am aware that this is not the answer you probably like to hear. 
But you need to understand that anything Internet related is kind of 
shoehorned/piggybacked on top of DOS, an operating system that was 
already officially declared dead by the time the Internet start to 
proliferate.


As everything https these days will require TLS 1.2 or newer to 
communicate, the only other thing you could do is to check with the 
authors about their tools supporting this level encryption...

Re: [Freedos-user] How to make the R-Alt key act like L-Alt?

2023-05-06 Thread Aitor Santamaría

Hello John,

Sorry for being late.

This can be tricky, but feasible with FD-KEYB without recompiling. You can
start from some US layout and try this example, for Alt+X

First, you need to find out the key and scancode that Alt+X produces (that
EDIT receives). I found this page, but there are utilities that may help
you out with this (like KEYCODE).

Keyboard scan codes (freepascal.org)


According to this, Alt+X returns scancode 2Dh  (45)

Define a plane for Left-Alt:

[Planes]
RALT

To emit simply a scancode with 0, you can do the / trick:

[KEYS:k1]
 45C  x  X   0/45

This should work.

Don't use SEARCH. (I didn't even know it exists.)

Just use DIR and assume a START.BAT being present in every directory:

[Freedos-user] How to properly use "search"?

2022-11-05 Thread Michał Dec


Hello again,

I'm trying to write a menu for playing games. The FreeDOS setup I've 
described earlier in my query on how to unload drivers will be presented 
in some local conventions. It's not just my personal gaming setup, I 
want to bring enjoyment to others. From past experience I know that 
letting random strangers have full reign over this computer is a really 
bad idea. One person vandalized FDAUTO.BAT with self-incriminating 
grafitti and created a bunch of lewd directories in random places. 
Another person nagged me constantly because they wanted to have Perl, 
because they found FDIMPLES and found in the package indices that 
installable Perl is a thing in FreeDOS. I caved in to those complaints 
and this individual waited until the convention is off for the night, 
and toiled away until the break of dawn writing a text-based adventure 
game in Perl. What a mad lad. Nevertheless, it's something I'd like to 
avoid in the future. That's why, I want to write a menu. If you remember 
those bootlegs cartridges for the NES that pack 999 games into 1 
cartridge and you simply select which one you want to play, that's more 
or less what I'm going for.


So, I wanted to implement this completely in Batch so that we don't run 
into the problem of taking memory that really demanding games, like 
Wolf, wish they could have. My idea is that I could put a Batch script 
in every game's directory where we can do simple things like start the 
game or run the setup, or regenerate the config to a known working 
state. In order to find games dynamically, rather than have a list of 
games written down in a file, I wanted to run SEARCH C:\GAMES START.BAT, 
but that started listing absolutely everything on C:\. When I tried 
doing SEARCH C:\GAMES\**\START.BAT, it printed some nonsense. How can I 
properly use the SEARCH command?


Best regards,

Michał

A DOS forum thread discussing this online claims that some of
those are only used for software mixing and concludes that you
should get things working with only CTCM and AWEUTIL as well,
so I guess you could test which of the 3 drivers mentioned in
your setup are REALLY needed for your games. Also, you can use
a boot menu to decide at boot time whether or not you want to
load your AWE64 drivers. Then you can select the no-driver boot
style for games such as Wolf which need more free DOS RAM :-)

Also, it seems CTCU /S can be run in autoexec instead of config,
which may be more convenient. CTCM = CreaTive Config Manager,
AWEUTIL = relevant for MIDI emulation for real mode games etc.,
CTMM and CTSB16 might be components which are less necessary.

Linux has been able to unload drivers (rmmod or modprobe -r) as far as
I can remember (the 2.0.x days at least). Linux drivers are most
definitely not in userspace unless it's a FUSE filesystem driver. There
is even a system service that automatically unloads kernel modules that
are unused after a while. FreeBSD also has a kldunload command. The
drivers are not in userspace either. In DOS it's up to the driver to
provide the unloading functionality. Ethernet packet drivers typically
can. I know Realtek and 3com drivers can because I made myself a batch
script to turn the network on and off in which I unload the packet
drivers to free some RAM. I think mTCP drivers can be unloaded as well.

I can't see how to get mode to do this, and the particular apps don't
allow use of a file as a printer.

Fortunately it's not a big issue. As I'm using qemu anyway, I can
easily save the lpt output. I have also found something I can use on
the host Linux box to interpret the PCL output and convert it it PDF -
gpcl6 from a local compile of ghostpdl. I've tested - the output seems
to be just fine.

2022-09-17 Thread Michael Brutman

I'm not going to be porting LPR to mTCP anytime soon; I think about 4
people would have a use for it.  However, if a printer supports JetDirect
printing on port 9100, then mTCP netcat can be used.  Simply have your
program print to a file, then use netcat to send the file to the JetDirect
port on your printer.  Most network printers can do this.

The detailed instructions are in the mTCP PDF file.

[Freedos-user] How to obtain LPR - or is there a way to use IPP?

2022-09-16 Thread Phil Reynolds

Now that I have got my FreeDOS setup working correctly again (a fresh
setup and copying over my old apps sorted it), I am looking into how I
might be able to print from some apps (normally they expect a directly
connected printer supporting either ESC/P2 or PCL). I have not found
anything about IPP being possible from FreeDOS, but if it is, that
would certainly help. However, the other alternative in my case would
be LPR. I have not found a package with LPR yet, and most links I have
found around the web either include anything but a binary or are
broken. I see mention of a source file for it as part of WATTCP but
have no idea how to get it, nor how to build it once obtained.

Of course, there might not be a successful way to get usable output,
but any suggestions would be welcome.

(The printer would be accessible directly or through cups running on
the host Linux system - and there may even be ways to provide any
additional filters required at that level - it is outside the scope of
this question to worry about that.)

Re: [Freedos-user] How to have sound with freedos under virtual box?

Hi Wolf.

I think it must be some kind of emulation for MS-DOS/Free DOS games, but
virtualbox will detect your inboard soundcard since we no longer use
external sound cards althoug i have see some from Creative on stores
where in Portugal.

The prodominant is external sound cards...

I don't use much virtualbox for DOS because of the speaker issue, just to
tryout. For DOS gaming i try my luck with dosbox or the variant X because
of the CPU types.

The alternative is to get my 286 to play

Hi Wolf,

See my other email.

VirtualBox (like any virtualization) provides a layer of abstraction
between the "guest" and the "host." The host is the operating system
where you run VirtualBox, the guest is the operating system you run
inside VirtualBox. In your case, the host is Windows and the guest is
FreeDOS.

VirtualBox has to emulate any hardware presented to the guest. That's
how the guest can "see" a hard drive that only it can use, because
VirtualBox has presented a virtual hard drive for it to use. Same for
the other hardware on the system, including sound devices. If
VirtualBox doesn't emulate some part of the hardware (such as the PC
Speaker) then it's as if that hardware doesn't exist for the guest. It
doesn't matter what the host has, it's all about what VirtualBox
emulates for the guest.

VirtualBox emulates a SoundBlaster16, so you can play games like Doom
(and a bunch of others) that use the SB16 for sound. To over-simplify,
VirtualBox emulates the SoundBlaster16 by "translating" the sound
waves that would have gone to the SB16 and playing them back on the
host's native sound system.

Unfortunately, VirtualBox does not emulate the PC Speaker. To be
clear, the PC Speaker was a special piece of hardware that used to be
included on early PC motherboards. The "PC Speaker" here doesn't mean
the speakers connected to your computer; the "PC Speaker" refers to
the internal speaker that generated beeps and other monotones. Early
games like Commander Keen also used the PC Speaker to generate sounds.

Short version of that is: VirtualBox emulates a SoundBlaster16 but not
the PC Speaker. So you won't hear "DOS system beeps" when booting
FreeDOS or any DOS under VirtualBox. Because VirtualBox doesn't
support it.

VirtualBox can emulate a SoundBlaster16, but does not emulate the PC
Speaker. So you won't hear beeps, since those are produced by the
internal PC Speaker and not through SoundBlaster. This is a limitation
with VirtualBox.

I use VirtualBox to boot FreeDOS on my Linux system. But if I need PC
Speaker output (such as standard DOS "beeps" and other monotones) then
I have to boot FreeDOS in QEMU, which can emulate the PC Speaker.

Re: [Freedos-user] How to have sound with freedos under virtual box?

Hi Joao.
The most important is speed for a simulation. Then comes sound in 
priority, but is important also.
What does mean " support only soundblaster"? I know i can configure it 
under virtualbox, but i have no real soundblaster, thats why i wrote 
what mainboard i have, with its soundchip.Would it be possible to buy a 
Soundblaster, perhaps an "USB soundblaster device" if it exists, and 
then i would have SB sound under freedos SUPPORTED BY virtualbox?

Any concrete hint would be appreciated.
Aim is to achieve to have sound in freedos under virtualbox on this host 
(Windows 10 wit the ASUS Z690)
