Chapter 3 BIOS Utility 3-37
PCI Slots
When you set the PCI IRQ Setting parameter to
Auto
, these
parameters specify the auto-assigned interrupt for each of the PCI
devices. If you set the PCI IRQ Setting parameter to
Manual
, you need
to specify the interrupt that you want to assign for each PCI device
installed in your system.
AGP
This item shows the assigned interrupt for the onboard accelerated
graphics port (AGP) controller.
PCI IRQ Sharing
Setting this parameter to
Yes
allows you to assign the same IRQ to
two different devices. To disable the feature, select
No
.
If there are no IRQs available to assign for the
remaining device function, we recommend that you
enable this parameter.
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 has
been updated. This allows the display of multiple images on the
screen.
