Parameter
PCI/VGA Palette Snoop
Chapter 2
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.
