X7DA3 User's Manual
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
Enabling this option provides the capability to boot from GLAN. The options are
Disabled and Enabled.
IPMI 3rd LAN OPROM Confi gure (*Available if the 3rd LAN on an IPMI
card is detected.)
Select Enable to allow the user to boot from the 3rd LAN on an IPMI card. The
options are Enabled and Disabled.
Onboard MASS Storage OPROM Confi gure (*Available if an onboard
MASS Storage Controller is detected.)
Select Enable to allow the user to boot from a onboard mass storage device. The
options are Enabled and Disabled.
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, with a payload size of 256 Bytes which inhibits the
coalesce feature. Please refer to your add-on card user guide for the desired setting.
The options are Payload (256 Bytes) and Coalesce Enabled (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.
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.
