PnP/PCI Options
The PnP/PCI Options menu allows you to specify the settings for your PCI devices. Selecting this option
displays the following screen:
The following table describes the parameters found in this sub-menu.
Parameter Description Options
PCI IRQ Setting Select Auto to let BIOS automatically configure the plug-
and-play (PnP) devices installed in your system.
Otherwise, select Manual.
Note: Refer to your PCI card manual for technical
information.
Auto
or Manual
PCI Slot 1 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.
User input
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.
Note: If there are no IRQs available to assign for the
remaining device function, we recommend that you
enable this parameter.
Yes
or 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 RAMDAC (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
RAMDACs. The signal goes through the cards
continuously until all RAMDAC data has been updated.
This allows the display of multiple images on the screen.
Note:
Some VGA cards have required settings for this
feature. Check your VGA card manual before setting this
parameter.
