Refer to your manual for technical information
about the PCI card.
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.
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.
