Video DAC Snoop lets you correct video problems that may occur when you use certain video expansion cards. The default is Off. If you are using a video expansion card and problems such as incorrect colors or blank windows occur, set Video DAC Snoop to On.

Video DAC Snoop Controls how VGA and graphics devices on the PCI or AGP bus respond to palette register accesses.

On — forces VGA and graphics devices to snoop VGA palette register accesses and forward them to the ISA bus.
Off — (the default) forces VGA and graphics devices to respond positively to palette register accesses
