Very strange behavior. My Magnavox 286 usually plays all VGA games in color. However: some games sometimes play in B&W. However: within the same boot up some games are color. :mrgreen:

There is a Cirrus Logic VGA on the MOBO. Any suggestions? I tried 2 CRTs: same story.

Update: turns out the VGA wants to confirm the CRT is color. So booting with CRT turned off solves it.

Often for chipsets, there will be a little program to force colour. If you can find the utils for your card, might be worth trying in autoexec.bat and seeing if the problem goes away.

The problem is avoided by first boot without CRT attached. I have the VGA BIOS utility that came with the system manual. It already has color enforced. Excellent suggestion though! Thanks!
