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.
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.
Altos 500 Series User's Guide
If there are no IRQs available to assign for
the remaining device function, we
recommend that you enable this parameter.
Some VGA cards have required settings for this
feature. Check your VGA card manual before
setting this parameter.
