[Resolved] DOS session does not work. Motherboard Asrock B85
« on: November 19, 2020, 10:31:02 pm »
After starting a full-screen DOS session, a screen with "C:\" appears as in the picture (see attachment).
After pressing any key, the screen closes and the popuplog.os2 is formed.
Code: [Select]
19.11.2020  22:58:30  SYS   0  PID 0038  TID 0001  Slot 00A7
C:\OS2\PMSHELL.EXE

EBP=00000A6A  FLG=000A6212

What can be done?
Motherboard Asrock B85. Bios UEFI and compatible.

Are you running AOS? If so, you should open an issue. I don't remember anyone having that failure.
If not, buying AOS 5.1 might help as UEFI DOS support seems better then BIOS based systems.

Hi Igor.

Are you with UEFI support enabled and with a latest ArcaOS on this machine. As far as I understood there were some changes/updated on the drivers to run VDM (Virtual DOS) on UEFI mode. Maybe the issue goes on that side.

If the issue is happening on ArcaOS 5.0.6 with UEFI mode, I think it will be good to open a ticket.

Not in a released version. It's an announced feature. As Dave wrote, it's planned for 5.1.

Okay, I'll update the system to ArcaOS in the future. Hope there will be Christmas discounts.
Or is it better to wait for version 5.1?

Version 5.1 might be 6 months away. (Always hard to predict)

What can be done?

Try to disable dos=umb

set
DOS=HIGH,NOUMB
in config.sys

and check in vdm settings of each dos session shotcut , incl win/os2 sessions

Ps dos+emm386 runs on this motherboard with
device=c:\dos\emm386.exe  /nomovexbda noems ram

Many big thanks!
Indeed, after disabling the UMB, everything worked!
Problem solved!

Greetings,

I have followed all of these tips on a thinkpad t430s with 1080 screen.  I have it mostly working, however once in DOS session I can get BBS started but for some reason if I do a simple "dir" command it closes DOS completely

Any thoughts

Regards,

Rick

Modify config.sys
DEVICE=D:\OS2\MDOS\VSVGA.SYS  /int10textgrfxsafe
And to autoexec.bat
mode co80
cls

See if that helps... works on my W530,
