AMI BIOS Setup

3-17

PNP/PCI Configurations

This section describes configuring the PCI bus system and PnP (Plug & Play)

feature. PCI, or Personal Computer Interconnect, is a system which allows I/O

devices to operate at speeds nearing the speed the CPU itself uses when

communicating with its special components. This section covers some very

technical items and it is strongly recommended that only experienced users

should make any changes to the default settings.

Clear ESCD

The ESCD (Extended System Configuration Data) NVRAM (Non-volatile Ran-

dom Access Memory) is where the BIOS stores resource information for both

PNP and non-PNP devices in a bit string format. When the item is set to Yes, the

system will reset ESCD NVRAM right after the system is booted up and then

set the setting of the item back to No automatically.

PCI VGA Palette Snoop

When 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:

1 2 ... 53 54 55 56 57 58 59 60 61 62 63 ... 84 85
