same IRQ to two differe nt devices. To disable the

VGA Palette Snoop This parameter permits you to use the palette snooping
feature if you ins talled more than one VG A card in the
system. The VGA p alette snoop function allows the
control palette register (CPR) to manage and update the
VGA RAMDAC (Digital Analog Converter, a color data
storage) of each V GA card installed in t he system. The
snooping process lets the CPR send a signal to all t he
VGA cards so that they can upd ate their individual
RAMDACs. The signal goes through the cards
continuously until all RAMDAC data has been updat ed.
This allows the displa y of multiple images on the scre en.
Note: Some VGA cards have required settings for this
feature. Check yo ur VGA card manual befo re setting this
parameter.
