Section 5 PCI/PnP Setup
Choose PCI/PnP Setup from the AMIBIOS Setup main
menu. All PCI/PnP Setup options are described in this
section.
AMI RAID Express Installed Set this option to Yes if the AMI RAID
Express is installed. The settings are Yes or No. The
Optimal and Fail-Safe settings are No.

this computer follows the Plug and Play specification.
Windows 95 is PnP-aware. The settings are Yes or No.

PCI VGA Palette Snoop When this option is set to Enabled, multiple VGA
devices operating on different buses can handle data from
the CPU on each set of palette registers on every video
device. Bit 5 of the command register in the PCI device
configuration space is the VGA Palette Snoop bit (0 is
disabled). For example: if there are two VGA devices in
the computer (one PCI and one ISA) and the VGA Palette
Snoop bit is:
Snoop Bit Action
Disabled
Data read and written by the CPU is only directed to the PCI
VGA device's palette registers.
Enabled
Data read and written by the CPU is directed to the both the PCI
VGA device palette registers and the ISA VGA device palette
registers, and the palette registers of both devices can be
identical.
This option must be set to Enabled if an ISA adapter card
installed in the system uses VGA palette snooping. The
Optimal and Fail-Safe default settings are Disabled.
Allocate IRQ to PCI VGA Set this option to Yes to allocate an IRQ to a VGA
adapter card that uses the PCI local bus. The settings are Yes
or No. The Optimal and Fail-Safe default settings are Yes.
