M S-7133 M -ATX M ainboard
This section describes configuring the PCI bus system and PnP (Plug & Play)
feature. PCI, or Peripheral Component 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.
Graphic Adapter Priority
This setting specifies which VGA card is your primary graphics adapter. Set-
ting options are:
[IGD]
The system initializes the IGD (internal graphic display) first.
(for 915G only)
[PEG/IGD] The system initializes the PEG (PCI Express graphic) first. If a
PCI Express graphic card is not available, it will initialize the
IGD. (for 915G only)
[PEG/PCI]
The system initializes the PEG (PCI Express graphic) first. If a
PCI Express graphic card is not available, it will initialize the PCI
graphic card.
[PCI/PEG]
The system initializes the PCI graphic card first. If a PCI graphic
card is not available, it will initialize the PEG (PCI Express graphic)
card.
[PCI/IGD]
The system initializes the PCI graphic card first. If a PCI graphic
card is not available, it will initialize the IGD. (for 915G only)
