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 default setting is Disabled.
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. 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 256 MB. The
default setting is 64 MB .
Plug and Play OS
When this parameter is set to Yes, BIOS initializes only PnP boot devices such as
SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices
such as sound cards. The default setting is No.
Reset Resource Assignments
Set this parameter to Yes to avoid IRQ conflict when installing non-PnP or PnP ISA
cards. This clears all resource assignments and allows BIOS to reassign resources
to all installed PnP devices the next time the system boots. After clearing the
resource data, the parameter resets to No.
