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.
Some VGA cards have required settings for this
feature. Check your VGA card manual before
setting this parameter.
