Parameter PCI/VGA Palette Snoop Description This parameter permits you to use the palette snooping feature if you installed more than one VGA card in the system. The PVI/VGA palette snoop function allows the control palette register (CPR) to manage and update the VGA RAMDAC (Digital Analog Converter, a color data storage) of each VGA card installed in the system. The snooping process lets the CPR send a signal to all the VGA cards so that they can update their individual RAMDACs. The signal goes through the cards continuously until all RAMDAC data has been updated. This allows the display of multiple images on the screen. NOTE: Some VGA cards have required settings for this feature. Check your VGA card manual before setting this parameter. Disabled Enabled Options Chapter 2 52
