Hi,
I used to be able to run OS/2 in 1024x768 mode using the GENGRADD driver
and the -stdvga flag back in October (CVS of October 10). Now I checkout
out the latest version from CVS and OS/2 only does the low resolution
standard VGA mode.
I noticed that the VGA BIOS was updated since October 10 and tried the new
Qemu with the old BIOS and it works fine at 1024x768 again.
Any ideas what went wrong with the BIOS update?
Thanks
Johannes

Hi,
Try to use the VGA BIOS taken directly from Bochs. My patches (see
qemu/pc-bios/vgabios.diff) were intended just to add some high
resolution modes.

Which version of the vga bios are we using in qemu? 0.4c (last release) or
CVS?
I don't really see why your patches should confuse the OS/2 display
driver...
Thanks
