Discrete MTRR Allocation
If enabled, MTRRs (-Memory Type Range Registers) are confi gured as distinct,
separate units and cannot be overlapped. If enabled, the user can achieve better
graphic effects when using a Linux graphic driver that requires the write-combining
confi guration with 4GB or more memory. The options are Enabled and Disabled .

PCI Confi guration
Access the submenu to make changes to the following settings for PCI devices.
Onboard GLAN1/Onboard GLAN2 (Gigabit- LAN) OPROM Confi gure
Select Enabled to boot from GLAN. The options are Disabled and Enabled.
Default Primary Video Adapter
This feature allows the user to specify which video adapter to be used as the
default primary video adapter--the onboard video adapter or others. The options

Emulated IRQ Solutions
When Enabled, the Emulated IRQ Scheme will allow PCI devices to run on legacy
operating systems that use the MSI mechanism to generate INTX compatible
interrupts. The options are Disabled and Enabled.
PCI-Exp. I/O Performance
Some add-on cards perform faster with the coalesce feature, which limits the payload
size to 128 Bytes; while others perform faster with a payload size of 256 Bytes
which inhibits coalesce features. Please refer to your add-on card user guide for the
desired setting. The options are Payload (256 Bytes) and Coalesce (128 Bytes) .
PCI Parity Error Forwarding
The feature allows SERR and PERR errors detected in PCI slots to be sent
(forwarded) to the BIOS DMI Event Log for the user to review. The options are
Enabled and Disabled .
ROM Scan Ordering
This feature allows the user to decide which Option ROM to be activated fi rst. The
options are Onboard fi rst and Add-On fi rst.
PCI Fast Delayed Transaction
Enable this function to improve DMA data transfer rate for a PCI 32-bit multimedia
card. The options are Enable and Disabled .
Reset Confi guration Data
If set to Yes, this setting clears the Extended System Confi guration Data- (ESCD)
area. The options are Yes and No .
