Hi, everyone.

I recently installed OS/2 on another computer and I just discovered that DOS and Win-OS/2 is not working. The window comes up and freezes, gives me a popup error and leaves. According to POPUPLOG.OS2:

02-03-2005 16:23:42 SYS3170 PID 0042 TID 0001 Slot 0069
C:\OS2\PMSHELL.EXE

SS:ESP=ffff:000008f2 SSACC=**** SSLIM=********
EBP=00000314 FLG=000a2206

I'm running Scitech SNAP/PE for the Intel AGP chip... other than that, I can't think of anything that would cause any problems. I did install DANIS506.ADD, but no other major modifications to the system.

Ideas or suggestions?

Thanks,
Sean

Was WinOS2 and DOS support installed when you instaleld OS/2? Perhaps they did not install completely?

OS/2 Warp-ed/eComStation-ed to the very end.

No, DOS subsystem is fine most likely. I have experienced the same problem as well. The "Chernobyl screen" says "trap 0E in VVGA" (trap 0E is the page fault). The crash happens everytime you try a windowed DOS or WIN-OS2 session or start a seamless WIN-OS2 session. Full screen sessions work.

This happens with some video cards under eCS. If it is the case, then you need the viotbl.dcp file from Warp 4 before FP5 or so. Get the file, rename viotbl.dcp in your \OS2\BOOT to something else and copy the old viotbl.dcp there. Reboot. For some unknown reason, all your problems will be gone, DOS and WIN-OS2 sessions will work, and you won't lose any functionality of the operating system.

Okay, I'll do that... I have my original Warp 4 CD around here somewhere. As for the questions:

1) Yes, DOS and Win-OS/2 were installed and working upon installation.

2) I suspect Scitech SNAP/PE is to blame for this-I will go back to VGA and try it...

Thanks to both of you for your responses! I appreciate them and will write this down in my "OS/2 Notes" book.

Thanks again,
Sean
