[comp.windows.ms] Generic 800x600 VGA driver

gavras@fokus.berlin.gmd.dbp.de (A. Gavras) (03/14/91)

Hi,
I have some problems here and would like to hear your suggestions.

I have a SVGA board installed in my 386SX. The VGA is an 8-bit, 256K
OAK Tech. board, the 386SX is an IT (Informtech, Hong Kong) board, with
4Mbytes installed.
The system was purchased about 2 years ago, so there is no driver for Win3
on the utility disk. I use the generic SVGA driver from cica.cica.indiane.edu
in the sv800.arc archive.
In the 800x600 mode all windows applications work fine too.
If I try to run a command.com session in a window in the 386-mode,
the system crashes immediately. Only the reset button brings the
system up again. I can run a command.com session in the fullscreen mode,
but the system crashes in the same way upon exiting the session.
I tried to find out if there is an incompatibility with any TSR programms,
without any success. I tried also an EMMexlude line in the system.ini file.
In the standard VGA mode with the standard VGA driver everything works fine.

Can it be a software bug in the generic VGA driver?
Can it be a hardware bug?
Can it be a software bug in the BIOS of the VGA board?

In the next few days I will try to install another VGA board and run it
with the same generic VGA driver to see what happens.
Until now I could not find a Win3 driver for this board. There is one on
cica.cica.indiana.edu (named OAK_800.DRV, that I suppose is for this board)
but it seems to be truncated. It has a size of about 2.5KBytes.
All other display drivers for Win3 have a size of about 72KBytes.

I would appreciate any responses and I thank you in advance.
