Vga Palette Snoop; Graphics Aperture Size - Acer 930 Bios Manual

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 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.

Graphics Aperture Size

This parameter determines the effective size of the graphics aperture.
Graphics aperture is the address range that the AGP video and the CPU use
to manage graphical objects. The lowest setting is 8 MB and the highest is
