I am writing a Video Display Driver and trying to support RGB 332 mode in
8bit color depth. I am using my device as an additional display card on a
system. So there are two cards on the system. One is the default device and
the other is mine. My device works fine on RGB 332 when it is attached as a
secondary device. Whenever I make my device primary on 8bit color depth then
system crashes and after doing !analyze -v the following trace is generated:

Thanks in Advance.
