Or, just put a note on the download page saying it requires X mb free space for 
a full install and Y for only Base. Then let the user worry about the problem.

I don’t recall the poll numbers for use case. But, I have the impression that 
the majority of users are not installing onto an existing system with minimal 
free space. Mostly, they are installing into a virtual machine. Some are 
setting up legacy hardware on clean machines. 

I just don’t see it as a problem should take priority over other issues. Maybe 
I’m wrong. But, that’s my 2 cents worth.

Re: [Freedos-user] freedos installation disk space requirements - was: Some driver updates

[Eric Auer]

Hi Jerome,

> Maybe the installer should just assume FULL install + sources

Not really. Almost nobody installs all sources at the same time
and I would not even want the option in the installer: Instead,
I prefer to have the option to install + PACKAGES with sources.
Then I can unzip only those sources that I need, instead of all
of them at the same time.

Also, I would hope that people understand that FULL will be 100s
of MB while BASE gives you everything you loved in MS DOS times
plus a lot more while still needing only a few dozen MB space :-)

In other words, I hope people will see that both FULL and BASE
are nice choices. You could disable the FULL install and show a
message why, if there is enough space for BASE but not for FULL.

You could do for example the following:

Calculate sizes of BASE and FULL and if you really think it will
help the sizes of either with sources. In all cases, assume 32 kB
cluster size to be on the safe side. In other words, round UP to
multiples of 32 kB. Then add 5 MB safety margin. And if desired,
2x the size of the old OS directory if "backup old OS" is active.

If there is less space than calculated, warn the user that FreeDOS
will probably not fit, but allow to continue nevertheless if the
user decides to continue. If there is enough space, tell the user
that the install will take circa PREDICTEDVALUE of FREESPACE and
leave REMAININGVALUE or more free. Then the user can be happy to
hear about the "or more" part :-)

Cheers, Eric

Re: [Freedos-user] freedos installation disk space requirements - was: Some driver updates

[Jerome Shidel]

I see a lot of  assume this, assume that, plus a little of roughly this... 

Maybe the installer should just assume FULL install + sources + (2x) old OS 
backup + 1-5MB  safety margin at startup. If there is not that much space, tell 
user the error and stop. Like several other dangerous things, the user could 
force an install in advanced mode.

Re: [Freedos-user] freedos installation disk space requirements - was: Some driver updates

[Eric Auer]

Hi Jerome,

>> Start with Base.

> Can’t. If user is doing a custom install

Yes you can ;-) Base install will be a common choice,
so it is good if you can at least predict how much
disk space is required for THAT. I think this also
is exactly why Robert wrote START with base: You can
always try to add perfect calculations for every
situation imaginable later, but it would already
help a lot to have any space predictions at all,
at least for common cases!

>> Shouldn't take much.

> Yes. But, everything counts.

Simply assume 1 MB for autoexec & install lists?

>>> Size needed for MBR backup,
>>> Size needed for config file backup,

>> Shouldn't take much.

> Correct, but if you're going to calculate stuff, should be accurate.

Look. At the moment, you do not give the user any
idea at all regarding how much space is required!

So what is better?

1. Tell the user that base takes 40 MB plus 5 MB
worst case for temp files, so 45 MB should be okay,
which given that our user is trying to install on
her 60 MB partition, there install will be smooth?

or

2. Tell the user to take any disk of random size
and brace for the random outcome of whether or not
installing FreeDOS base on it will succeed? :-p

I have an *extreme* preference for the 1st case.

Of course "40+5 MB" is just an example, but based
on actual packages, you can make good estimates.

> A 52 byte file may use 512 bytes on disk.
> So, just adding sizes is no good.

Exactly what I said: Please assume that all file
sizes are rounded up to the next multiple of 32
kilobytes (largest common cluster size on FAT).

Then your error will always be that you over-,
but never under-estimated required space. Which
means that if you say the install WILL fit, it
WILL fit. And when you predict it will NOT fit,
it MAY fit, but the user has to try at own risk.

Much better than no help at all, I would say :-)

Regards, Eric

Re: [Freedos-user] freedos installation disk space requirements - was: Some driver updates

Hi Robert :-)

>> Base size,
>> Base + sources size,
>> Full size,
>> Full + sources size,
>> All package sizes (custom advanced mode)
>> All packages + sources sizes,

> Start with Base.

Actually I would suggest to never install complete categories
WITH SOURCE. Just install sources of individual packages when
needed and simply keep the rest stored in their zip packages.

To find out BASE size, I suggest to compute required size
based on the assumption that each cluster is 32 kB large.

You can either precompute that for a fixed distro, or let
the installer compute things based on actual zip content.
Of course the latter means more reads from the installer
medium - slow, unless you have a nice cache active.

>> Temp storage requirements to expand largest installing package,

> Difficult.

Just add a fixed margin for such stuff?

>> Temp storage for custom install lists,
>> Temp storage for custom autoexec and config file creation,

> Shouldn't take much.

I agree. Use fixed margin.

>> Size needed for copy style backup,
>> Size needed for advanced zip backup,

> Means what?

Probably means size of the current DOS directory which
can be backed up during install by either xcopy or zip.
Should be answered by something like "du \freedos" ;-)

>> Size needed for MBR backup,
>> Size needed for config file backup,

> Shouldn't take much.

I agree. As above.

>> Size of packages to be removed and upgraded,

> It's just "-", not "+" then. ;-)

Just ignore all remove / upgrade steps for now: This
gives you a most pessimistic estimate. When there is
still enough disk space, be happy. When not, show a
warning and allow the user to proceed at own risk :-)

This is still a lot better than letting users create
FAT12 drives in the blind assumption that DOS is tiny
and then be surprised by failed attempts to install
"all packages" into them ;-)

> Of course, uncompressed ZIP length should be calculated during ISO
> build at the latest, but not at runtime of the installer.

See above - both is possible. Do not forget to stay
on the safe side by assuming large clusters on the
drive where DOS will be installed. Or pre-compute
for various cluster sizes and then pick the value
which matches the actual target drive.

> But what else is a computer for if not crunching numbers?

Exactly :-)

Try one of Ulrich's pre-installed images instead, and see if the

https://www.lazybrowndog.net/freedos/virtualbox/

It could be something rare (RAM or hard drive problem), but for now
I'm assuming otherwise.

> Is this a VirtualBox issue?

Maybe. Which version (5.x? 64-bit? host OS?) are you using? VT-X
enabled? Other relevant settings (e.g. memory managers loaded? HIMEMX
only? JEMMEX?)?

You could maybe file a VBox bug report, but you'd have to give them a
LOT more details. Besides, I don't think DOS is top priority for them
to fix anyways. Honestly, it's probably user error (more likely than
not) than actual bugs, but you never know.

> Is this a FreeDOS issue?

Highly doubtful. What kernel ("ver /r")? Never mind, presumably
whatever came with 1.1 (e.g. 2040).

> Thanks for anyone's help.

You could also just use QEMU instead. Some prebuilt Windows binaries
(e.g. 2.5.0) are here:

[Freedos-user] Freedos Installation

[Nolin Chitnis]

Hello

I tried to install Freedos 1.0 on a SD card using Unetbootin. I used
the Freedos from the drop down menu of the latest Unetbootin version
and ran the process to write it on the SD card. After completion the
install manager asked me for a reboot which I did. The Freedos program
ran correctly with the Freedos installation being visible on A: and
the unebootin files on c: (both on the SD card I guess).

But when I shut down the PC and try to reboot again from the SD card
the PC hangs at the prompt SysLinux 4.03 2010-10-22 EDD
Copyright. Nothing happens after that.

In effect FreeDOS is able to boot only once. What is the reason.

Re: [Freedos-user] freedos installation using usb drive

[gabriel borrageiro]

hello,
 
good news... I have a working usb boot disk (windows 98 boot disk).
The problem I have now is that the usb drive loads as disk 1, so when I run 
fdisk, the usb disk is assigned as the active partition.
Therefore even if I install XP on my hard drive, the disk will not load 
correctly without the usb drive as it's not the active partition.
If I try run fdisk to force the hard disk to become the active partition, this 
does not work. Only drive 1 can be made into the active partition. And 
according to fdisk, the usb drive is the active partition in drive 1.

Re: [Freedos-user] freedos installation using usb drive

[Jonathan W.]

That depends. First, go into your BIOS and see if it supports booting from
USB; you should be able to find this out by going into the Boot Order
menu. If there's a USB option, then yes, you probably can; otherwise, no,
you'll have to find a floppy drive somewhere.

If your computer is new enough that it doesn't have a floppy drive, it's
probably new enough that it should be able to boot from USB... just check
and see. If so, then I think there's a USB image for FreeDOS, but I'm not
sure where, someone else might know.

Re: [Freedos-user] freedos installation using usb drive

[Alexandru Fira]

  If you do not have a CD drive for your PC, then it would be useful to buy a 
USB CD or DVD-RW drive. It is always useful, so it is not a waste of money. You 
can use later for a lot of interesting things. And it is not very expensive, 
around 100 RON in Romania, so 32 dollars.
  I have Freedos on a stick now together with Damn Small Linux and Puppy linux. 
The MBR was messed up on my stick and could not make the Fat32 partition 
bootable, so I edited the menu.lst file in Grub to look like this:










default 0
timeout 10
title DSL
root (hd0,1)
kernel /linux24 ramdisk_size=10 lang=us quiet vga=791 frugal   
initrd /minirt24.gz
title Freedos
root (hd0,0)
makeactive
chainloader +1
boot
title Puppy Linux 400 frugal
rootnoverify (hd0,0)
kernel /puppy400/vmlinuz pmedia=idehd psubdir=puppy400
initrd /puppy400/initrd.gz

I bolded what should be added to make the Fat32 partition bootable even on a 
messed up memory stick.
 This can easily be done by booting Slax or Puppy Linux and simply writing that 
code for Freedos (of course, taking in account on which partition it is.)
I am using Freedos for some DOS games now and I am very sad I cannot access the 
Internet under freedos.

  Yes, you are right, a new hardware may be a great surprise for Windows XP 
whereas under Linux things went smoothly
when putting the HD into another computer.

  I wish a Happy New Year to everybody !

[Freedos-user] FreeDOS installation ISOs

[Simon Atkinson]

Hi there ... just a quick query: what is the difference between the

 files/distributions/1.0

and

files/distributions/1.0/3sep2006

..except the latter contains zipped files. Does the former contain more
up-to-date ISOs?

Thanks

Simon

There was an error in the ISOLINUX config of our ISOs
so Jim remastered them. The files inside the ISO are
supposed to be the same, but the new ISOs will boot on
more BIOSes than the original 3 sep 2006 ISOs, I hope.

Let me know if you find something interesting in the
zipfiles of the original 2006 backup directory :-)

Re: [Freedos-user] freedos installation on dos partition on linux system

[tekno1911]

You should backup your boot/mbr sector first to a blank floppy with
following command: 

dd if=/dev/hda of=/dev/fd0 bs=512 count=1

because if after installing freedos on that dos partition lilo or grub
dont come up next boot than you can restore it with dd if=/dev/fd0
of=/dev/hda bs=512 count=1

Re: [Freedos-user] freedos installation on dos partition on linux system

[Eric Auer]

Hi Bonnie,

I recommend to use a normal file, not /dev/fd0, to
save the mbr. Of course you should put a copy of the
file in a place where you can reach it if your Linux
cannot boot from harddisk. To backup the mbr of the
second harddisk, use /dev/hdb instead of /dev/hda,
and so on. a / b are primary ide master / slave, and
c / d are secondary ide master / slave. However, dd
is a dangerous command to use, so you should read
the docs and double-check for typos.

  the freedos installation from the cd says soemthing about the
  installation on a harddrive overwriting the os so i was very nervous

What exactly does it say? FreeDOS can only install to FAT
partitions, so all Linux and Windows-NTFS partitions are
ignored anyway. You should not use FDISK or similar tools
during install, unless you know very well what you are
doing. It is much better to use Linux or Windows tools
for that, as they are powerful and easy to use. If you
already have a (preferrably primary, otherwise the boot
loader config will be tricky) FAT partition, then there
is no need to change the partitioning at all.

So... if you have a FAT partition, and it should be a
FAT16 one (FAT12 are too small and FAT32 are sometimes
hard to make bootable, but you CAN use FAT32), a LBA
one if it is not entirely in the first 8 GB of the disk,
then the FreeDOS installer should automatically do the
rest. It will create a directory for FreeDOS, try to
find out if another DOS or Windows is already on the
partition, and try to set up a boot menu. If the boot
menu setup fails, it might happen that you can only
boot FreeDOS but not the other system afterwards. You
can usually fix this by using a boot disk of the other
system to make the other system bootable again, but
then FreeDOS will not be bootable any more... ;-).

  i can just copy freedos from the standalone harddrive to the dos
  partition. will that work if i can figure out  how then to use
  chain load to have GRUB present the dos partition as a boot choice.

It is easier to use LILO instead of GRUB for that...
A sample GRUB config snippet from this list, plus comments:

title FreeDOS
# hd0,0 would be what Linux calls hda1, read the docs:
root (hd0,0)
# not needed:
#   makeactive
# to use a file:
chainloader /somedir/freedos.bss
# to just boot the main OS of that partition:
#   chainloader +1
boot

Normally you can use whatever your Linux config center
creates when you select something like add 'Windows'.


To make a partition boot FreeDOS INSTEAD of what it
booted before, just run FreeDOS SYS X: (to do that
with the X: partition). Check which partitions are
which drive letter for DOS first.


To only ADD FreeDOS to a boot menu instead, leaving
the old operating system unchanged, use something
like SYS X: freedos.bss bootonly. Read the SYS /?
output for the exact syntax. This will only save a
boot sector to file freedos.bss, and you can tell
LiLo, Grub or the Windows NT/2000/XP/2003 boot menu
to use that file as chainloader. Note that bootonly
means that kernel,sys and command.com will NOT be
copied. Copy the kernel manually (with COPY) and
put command.com in the FreeDOS directory, so it
will not overwrite the command.com of your Windows.


If your other operating system also uses config and
autoexec, and you want a different configuration for
FreeDOS, create a fdconfig,sys file for FreeDOS and
fill it with whatever FreeDOS should use instead of
the config,sys contents. You can combine that with
a shell command like

SHELL=c:\fdos\bin\command.com c:\fdos\bin /e:512 /p=fdauto.
bat

to also make FreeDOS use another file instead of the
normal autoexec. So you can keep all config separate
from your other DOS or Windows operating system.


Note that you will not normally have to do anything
of this manually, as the installer should do it for
you automatically. IF that fails, make sure to have
a boot disk of your other DOS / Windows operating
system around, for the repair described above.

i have used this method of booting since i installed linux which was

Since I already had a small Fat32 partition as hda1 which was not being

Then I opened menu.ls and edited in a menu choice as Eric described:

It worked without my haviing to go back to the Freedos CD and try to

I really appreciate Freedos and the help from this list.

Re: [Freedos-user] freedos installation

[Lester Vedrox]

James, I'm not sure if you really got all your partitions right. The most  
common configuration is as follows.

You can have up to three primary partitions and one logical partition.  
Each primary partition can be made active or bootable (which means the  
same thing). Most operating systems must be installed on a primary  
partition. To avoid conflicts and problems the best idea is to install  
each operating system on a dedicated partition. Before booting you should  
make one primary partition active (eg. the one with FreeDOS) and all  
remaining primary partitions hidden. As far as logical partition is  
concerned (drives D to Z) FreeDOS won't see any NTFS drives.

Here is example of how the hard drive could look before you boot to  
Windows XP:

- Drive C, NTFS,  primary, active, Windows XP
- Drive -, NTFS,  primary, hidden, Windows 2000
- Drive -, FAT32, primary, hidden, FreeDOS
- Drive D, NTFS,  logical, visible to XP  2000, not visible to FreeDOS
- Drive E, NTFS,  logical, visible to XP  2000, not visible to FreeDOS
- Drive F, FAT32, logical, visible to XP, 2000 and FreeDOS

Now, to boot to FreeDOS you would have to use the boot manager and get the  
following:

- Drive -, NTFS,  primary, hidden, Windows XP
- Drive -, NTFS,  primary, hidden, Windows 2000
- Drive C, FAT32, primary, active, FreeDOS
- Drive -, NTFS,  logical, visible to XP  2000, not visible to FreeDOS
- Drive -, NTFS,  logical, visible to XP  2000, not visible to FreeDOS
- Drive D, FAT32, logical, visible to XP, 2000 and FreeDOS

You could consider creating this extra Fat32 logical drive (F under XP, D  
under FreeDOS) to easily transfer files between XP and FreeDOS and also  
for installing DOS applications (you can then defrag them from XP).

Boot Manager: grub4dos is often mentioned on this forum but I don't have  
the link. I use this freebie and it works great:

http://www.boot-us.com/

Once you get everything running in this basic configuration then you can  
try to experiment installing two OSes on the same primary partition but  
that's when things get much more complicated.

Re: [Freedos-user] freedos installation

[James Haley]

Thanks to your tip I was able to capture the error message:

--
C: HD1, Pri[1],CHS=   0-1-1,start=   0 MB,size=   1027 MB
D: HD2, Pri[2],CHS=   0-1-1,start=   0 MB,size=   3380 MB
IO error: cylinder  1023
IO error: cylinder  1023
Press F8 to trace or F5 to skip CONFIG.SYS/AUTOEXEC.BAT
--

Pressing any key at this point causes the invalid opcode error to occur,
although in a different fashion (it happens only twice, and pressing any
key after that does nothing at all).

I'm guessing it doesn't like my hard drive, since it's complaining about
cylinders.  The drive being identified as C: in this case is the drive
called D: if I boot from the CD-ROM. It's a Seagate ST51080a with
1 GB capacity. There was some kind of warning about DOS possibly
requiring it to be configured as 525 cylinders, 64h, 63 sectors instead
of the default 2100 cylinders, resulting in halved disk capacity, but my
BIOS will not allow me to change the disk's configuration. It has
already decided that it has 2100 cylinders and there is no option to
manually configure it.'

I should be able to dual boot, since my BIOS has a built-in boot
manager that lets me choose either the primary hard drive, the
secondary hard drive, the DVD drive, or the network. But since I can't
get this hard drive to configure properly, I guess I'm out of luck?

Hi James,
as far as I understand, your XP is still fine, but the
problem is that dos installed itself into the first DOS
partition, which happens to be your recovery partition?
The strange thing here is that your recovery partition
was supposed to be invisible - neither windows nor dos
should have a drive letter for it.
You can hit the pause / break key on the upper right
of your keyboard to read that io error message.
How big is your disk and does your bios detect the
disk size correctly?
You cannot boot DOS from what DOS calls D:, but you can
install packages to any drive which is visible for DOS.
From which operating system did you run sys d: ?
About the error messages - it is just a crash, and it
does not make any difference that you get 1000 identical
error messages about it. Windows would just have silently
rebooted or frozen in such a situation.
About installation again: Either hide the recovery partition
(if Windows has no interface for this, use Linux to set the
partition type from fat32lba to hiddenfat32lba). Then DOS
will call your slave drive c:, or install most of the stuff
to d: and leave the actual DOS kernel on your recovery
partition (as well as config sys or fdconfig sys). Everything
else can be on any drive letter...
You will have to use some sort of boot menu in either case,
as I assume that you want to keep both DOS and Windows on
the same computer. Windows includes one, configurable via
boot.ini... Please send your reply to this mail to the
mailing list again. Thanks!

Eric

PS: If you used beta9sr2 - that one is far too automatic
and a bit outdated. Sorry about that.

Re: [Freedos-user] FreeDOS installation gone wrong

[16 BIT]

Let us hope the MBR is not screwed up and it doesn't sound like it is.

Next time save the MBR before doing OS installs if you have a boot loader
which I think you do.

If you reinstall Windows, it will overwrite the MBR and you might have a
hard time booting to Linux.

Having said all the above ...

I think this will fix your problem. 

Make a Windows (MS-DOS) boot disk with SYS.COM on the disk. If you can't
boot this could be hard. If you don't have a boot disk, you can usually
download one from the Internet. Also you could make one from some other
computer.

Please don't tell me you have ME because I don't want to know about ME and
its DOS. If you do have ME you may want to disregard my advice.

Boot from the MS boot disk and then type:

SYS A: C:

This will not affect the MBR but will write a new boot sector on drive C.

It will also transfer IO.SYS and COMMAND.COM from A: to C:. I forgot if it
transfers MSDOS.SYS, but I think so. Be sure to *backup C:\MSDOS.SYS* as
you WILL want it in the event SYS causes it to be overwritten.

Also, you can put the FreeDOS utilities on D:, but you can't boot from D:
without some kind of special boot loader that I know nothing about.

16BIT, you're completely correct.
create  a Win98 bootdisk (or whatever Windows version you are using),
with SYS.COM on it.
then boot from it,
backup MSDOS.SYS ( COPY C:\MSDOS.SYS C:\MSDOS.BAK)
then copy over the system files from A: to C:,
then restore msdos.sys
a reference msdos.sys can be found at http://www.mdgx.com/msdos.htm
no idea what caused your problem (no c:\kernel.sys file present???),
but it will be corrected when a new FreeDOS release is out.

Re: [Freedos-user] FreeDOS installation gone wrong

[Rakhesh Sasidharan]

Hi,

In addition to what others have said about restoring the Win 98
bootsectors, I'll suggest one more thing. Restoring those bootsectors
will allow you to boot into Win 98 fine from LILO, but you still have to
do things to be able to boot into FreeDOS. 

For that, what I'd suggest is to re-install FreeDOS and when it asks if
you want to install the bootsectors, choose NO. Then, when it drops you
into the command prompt, type SYS D: to install the FreeDOS
bootsectors onto D:. It might give an error about KERNEL.SYS not being
found (it gave for me), but you can solve that by changing to C: and
then doing SYS D: (this is coz the KERNEL.SYS file is installed onto
C: for some reason). 

Now you can add an entry into LILO for booting this D: partition. And
FreeDOS should boot fine. :)

By the way, I said to re-install above coz I don't remeber the exact
installation steps and so am not sure if there's some option to simply
get to the FreeDOS command prompt (in case of Win98 you had the startup
disk, in case of FreeDOS I dunno). Once you get to the command prompt,
you can simply do SYS D: (and the rest of the steps) like I said above
... and you are done! 

Hope that helps. Welcome to FreeDOS! :)

Thanks,
Rakhesh
