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 goes through the cards continuously until all RAM DAC data
has been updated and allows the 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.
