Subject: Multiprocessor Bug ???
HI, I'm Mirco
and I tried to use dosemu on my linux server but when
I start it on dos prompt appear this message :
division overflow
and the prompt come back.
I've tried it on another server and all works fine,
the only differences that I have is that the first
have 2 processors (PII 350 - Linux 2.2.9 ).
What can I do ????
Thanks
Mirco

Subject: Re: Dosemu-fault (linux-crash)
Hello,
I'm having the same problem as you. I'm running slackware 3.6, kernel
2.2.7, and dosemu 0.98.6. Unfortunately, that's about all I can tell you
because my system isn't logging.
I've used the script setup-bootdir and altered my dosemu.conf to point
to that bootdir.first place and had the script get the necessary files
off a windows 95 bootdisk. I load dosemu, then try to execute a command,
doesn't have to change to the floppy drive, try copying a file from the
floppy drive, and it bombs out. I'm immediately kicked all the way out of
linux and I have to relogin, I'm using a terminal. I've simply copied
dosemu.users.easy to /etc/dosemu.users.
Hope this information helps. Any advice appreciated.
Thank you, and keep up the good work.
Dave.

problem #1 dosemu locks up when using floppy:
the solution to this was posted to the mailing list just yesterday.
Have a look at the mailing list archive at http://www.dosemu.org
problem #2 you can't use Linux once dosemu locks up:
I expect this is because you are running dosemu on the console.
If you run it under X, you should not have this problem.

Hi, thats funny. In my linux 2.2.9 SOL_IPX is declared in
/usr/src/linux/include/linux/socket.h. I don't know why the compiler
doesn't find it.
By the way, dosemu-0.66.7 is rather old. You could look for a new
version at ftp.dosemu.org/dosemu for the latest stable version (0.98.6)
and ftp.dosemu.org/dosemu/Development for the latest developer version
(0.99.11).

I've seen this problem a lot lately -- some package has been archived at
site X for years, and everybody *knows* it can be found there, then for
some reason the maintainer moves it or stops forwarding updates or
whatever, and somehow the word never gets out. (Witness the note from the
Metalab archivist. A *lot* of packages just stopped being sent up to
Metalab, apparently without a word of explanation.)
Please, if you're going to switch primary sites, or de-mirror a site, ask
the site maintainers to clean out the old package and replace it with a
pointer to the new list of canonical sites.

Actually, I am using VP/ix on Interactive Unix (AT&T Unix). We run serial
terminals off the unix box. The serial terminals are actually "stripped down"
PC's booting DOS and running terminal emulation software emulating the Wyse60
terminal in PC TERM personality. The result is, while running a DOS
application, the appearance of the PC console to the user whether on the actual
console or at a serial terminal. For the user, the display and keyboard on the
dumb terminal appear exactly as expected.
As Dosemu cannot properly handle the serial terminal case and as Dosemu has
other limitations in its present state, I have not been able to replace the
Interactive Unix system with Linux.
But the Dosemu developers have produced amazing results when it comes to the
capability of Dosemu to handle a graphic intensive application at the console.
I do not buy support for VP/ix so I do not know about support for it. I believe
that Sunsoft still sells Interactive Unix.
Cheers,
Robert

using xdos graphisc looks strange - almost everything is blue and only
~2 of each 8 vertical columns are displayed. I think there could be
some problem with video ram mapping, I'm using 16 bpp in X. Does anybody
have an idea or a fix ?

This (problem #2) is actually a known problem. It�s basically the main reason I
developed the boot_dir stuff in the first place for.
At the moment booton/-off simply does not work. I�ll fix this in the near
future (unless someone else does, that is :-) ).

Hi Mirco,
ara there applications in your autoexec.bat, that do delay-loops and
can't cope
with your fast processor? Turbo Pascal has that problem, if you use the

Subject: Dosemu on Acer 370 - Video problems
Has anyone got Dosemu set up on this Laptop?
I have Dosemu 0.98.6 on this, and am stuck with the settings. In
/etc/dosemu.conf at about line 105, I have the following
$_video = "vga"
$_console = (0)
$_graphics = (1)
The above settings because I need vga to use the programs I am running,
particularly t4040.exe for driving my Analogue Signature Analyser, for
faultfinding on Electronic Hardware, and Megazeux, for keeping my kids
amused. T4040 needs vga, and Megazeux uses enhanced Ansi; both are
otherwise primitive Dos programs which should present no hassle. If I
set $_console = (1), and $_graphics = (0), dosemu runs with no problems,
but T4040 finds no VGA card, and Megazeux looks like a bad trip on
something very strong :)
$_videoportaccess = (0) # Is this right?
$_vbios_seg = ???? #set the Address of your VBIOS (e.g.0xe000)
$_vbios_size = ???? # set the size of your BIOS (e.g. 0x8000)
$_vmemsize = ???? #size of regen buffer.
1. Can anyone tell me how to set these? The system reserves upper
memory, and I have not managed to get a breakdown of what's going on
there. The only thing information I can get is from Norton's SYSINFO,
(v6.1 ) which tells me
"Video Memory - 256K or more (2 Megs, I think)
Video Segment Address - B800 hex
Video Page Size - 4096 Bytes
32 K-Bytes display memory (at B800 - C000 hex)
ROM-BIOS Extensions are found at hex paragraphs: C000"
The BIOS on this are Acer's own, not AMI or Award. They have reserved
scores of Software interrupts, which SYSINFO lists addresses for; most
but not all begin with F000. Here's the ones that mention video:
05 Print Screen F000:FF54 BIOS
10 Video 0638: 0819 BIOS
1D Video parameters F000: F0A4 BIOS
1F Video Graphics Characters C000: 7371 BIOS
42 Relocated Video Handler F000: F065 BIOS
The Bios also have Hardware IRQs 9, & 13; Sysinfo claims 13 is for the
coprocessor, so I presume 9 is for the video.
Under "Device drivers" I get
0638:0000 CON Console keyboard/screen
0071:0006 CON Console keyboard/screen
I probably have the answer to my own questions here, I just can't
make sense of it.
2. The Dosemu-Howto makes reference to a program called "GETROM"
which apparently dumps the video bios to a file, and there are options
for using it in the HOWTO....around line 1400 :-(( . Has anyone a url
for this?

Like you'd do with a normal dos drive: for msdos 7, virtually boot from a
system disk (with system files and sys.com, at least) and sys X: where X:
is the name of the drive you want to transfer your system: for your main
diskimage, C: would be the one to use. You'll probably want to copy the
files in the \windows\command directory if moving to dos7, since that's
where the usual dos applications (xcopy, etc) reside.

Could you just tell wat kind of equipment ? Or is it about those nuclear

JK ...
Well, I have almost the same problem with a controling proggie for a
satellite dish.
That prog is called HRPT.EXE, and it can display all characters but no
numbers, dots or similar.
(No char with an ASCII value less than 0x40)
That is a SuperVGA (VESA) application, so is another kind of problem.
Does your proggie run in VESA too, or in plain text (CRT) mode ?

I fixed this by giving in the $_ports = "" line in dosemu.conf the
access to the io ports for the serial uarts. That is because a lot of
proggies claim to be so genious to fiddle around with the hardware
themselves.
Do "cat /dev/ioports" to see where your serial port are (range of
ioports).
Then add for example $_ports = "range 0x2f8 , 0x2ff" to the dosemu.conf
(the ports will vary dependent on your hardware) .
A fine tool for getting to know the hardware you DOSEMU can "see" is
MSD.EXE by Micro$oft.

That is the one I am using, I tried 0.99_11 development, too.

Subject: DOSEMU 0.98.6 floppy problems/lockups etc...
As this has been asked quite frequently during the last days:
If you have any floppy related problems (eg. dosemu locks up while
accessing it or you cannot boot from it or whatever), please
apply the patch below (will be integrated in 0.98.7).
Note that the patch I posted in the thread
"floppy A: B:, vbootfloppy and 0.98.6"
was broken; use this one instead.
Bye,
Steffen

Hello:
This is my first time to write you, I have a problem with dosemu
clock, I start dosemu and 30 min. later the clock go back for 1 hour,
for example I start at 8:00, at 8:29:50 i execute time and dosemu say
8:29:50, at 8:30:00 say 7:30:00 and if i execute unix date, it say
8:30:xx. If I wait for some hours the dosemu clock doesn't pass 8:30:00.
My kernel is 2.0.36, my dosemu level is 0.98.1.0 and i'm running
MS/DOS 3.3 (and i probe with IBM DOS 6.0, freedos, ... and i had the
same problem)
Thanks for your help.

If you use 0.98.6 or above, the easiest way is the following:
- create a directory, say /dos
- move io.sys, msdos.sys, command.com to /dos
- add your favorite config.sys/autoexec.bat
- put a symlink in /var/lib/dosemu pointing to /dos, say
ln -s /dos /var/lib/dosemu/dos
- change the $_hdimge line in /etc/dosemu.conf to
$_hdimage = "dos"
That�s it. Works with MS-DOS up to (at least) version 7.
If you want to try a different flavor of DOS, you�ll need an additional
step:
- put this DOS�s boot block into /dos/boot.blk
dd if=/dev/xxxx of=/dos/boot.blk bs=1b count=1
(if your DOS is on /dev/xxxx (xxxx may be hda1 of fd0 or whatever))

Which version of dosemu are you using? I�ve been using up to 0.99.9
on Dual-PII/350 machines without problems (up to kernel 2.2.5).

Subject: Re: xdos and VGA graphics
Hi Samuel,
I looked into this about a year ago, as I also have a 640x480x16
legacy DOS app I wanted to run under xdos. Unfortunately, the X
interface for DOSEMU does not bother to implement the 16-color
graphics modes of the VGA - just 256 color modes or better. When you
get down to it I guess, those 16-color modes haven't been used by many
people since the late 1980's for doing graphics mode stuff, so I can
understand the DOSEMU developers not putting any effort into it.
Having done most of my graphics related programming under DOS in the
late 1980's, I can tell you that the 16-color mode of the EGA/VGA is a
LOT more complicated than the 256 color modes. 256-color modes are
organized simply as a large array of bytes, with one byte per pixel,
along with a 256 entry palette table, saying what 24-bit color each of
the values 0-255 map to. Nice and easy to implement. The 16-color
modes of the EGA/VGA are implemented as 4 planes, with 1 bit per
plane, per pixel. You have to do a lot of AND/OR bit level operations
across the planes to get the output color 0-15 for a specific pixel on
the output display. This is just so much more complicated than
256-color and better VGA modes that it is ridiculous.
The only solution a year ago was to run those 16-color graphics apps
under DOSEMU in console mode, and it appears to still be the only
solution available under DOSEMU - unless someone want's to jump in and
implement it! I am capable of doing it, and am very familiar with how
the 16-bit graphics hardware is implemented - but I sure don't have
the time to mess with it...

You may or may not get better results using a recent development
version, eg. dosemu 0.99.9 or better.
This will eventually get fixed. Not in the near future, AFAIK.

Lredir isn't yet supported by freedos. (This is actually documented in

freedos still does not support lredir yet (it is mentioned in the HOWTO
and the READMEs - perhaps it would not be a bad idea to put a message
in lredir saying "warning, as of 27 May 1999 lredir does not work under
FreeDOS" for people who don't read the documentation)

This (problem #2) is actually a known problem. It�s basically the main reason I
developed the boot_dir stuff in the first place for.
At the moment booton/-off simply does not work. I�ll fix this in the near
future (unless someone else does, that is :-) ).

The following will make /mnt/floppy available as drive F: in DOSEMU
lredir f: linux\fs/mnt/floppy
Put this into autoexec.bat or as an "install="-line into config.sys.
To undo the assignment enter
lredir del f:
And, if you run out of drive letters, don't forget the "lastdrive=z"-line
in config.sys.

We did. The canonical site for DOSEMU *was* tsx-11. We placed a note on
the TSX-11 site quoting www.dosemu.org & the ftp address when we could no
longer reliably upload and we got the dosemu.org domain. The LSM entry was
also updated to list ftp.dosemu.org as the primary site.
The problem is with sites mirroring others and not paying attention. We
are not responsible for notifying the mirrors of a mirror site (or even
the mirrors of a site we don't adminster) *IF* people registered their
mirror sites with us then we would notify them of any changes. We have
only a few *registered* sites, although we know (and list) a few others on
the FTP/WWW site.
