VGA Palette Snoop

This parameter permits you to use the palette snooping feature if you
installed more than one VGA card in the system.
The VGA palette snoop function allows the control palette
register (CPR) to manage and update the VGA RAM DAC (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 RAM DACs.
The signal go through the cards continuously until all RAM DAC data
have been updated. This allows display of multiple images on the
screen.
Some VGA cards have required settings for
this feature. Check your VGA card manual
before setting this parameter.
