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 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.

data, the parameter resets to
No
.
