or written into L1, L2, L3 cache inside the CPU to speed up CPU operations. Select Uncached to disable this function. Select Write Through to allow data to be cached into the buffer and written into the system memory at the same time. Select Write Protect to prevent data from being written into the extended memory area above 1MB. Select Write Back to allow the CPU to write data back directly from the buffer without writing data to the System Memory for fast CPU data processing and operation. The options are Uncached, Write Through, Write Protect, and Write Back.

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 Configuration

Access the submenu to make changes to the following settings for PCI devices.

Onboard GLAN1/Onboard GLAN2 (Gigabit- LAN) OPROM

Configure

Enabling this option provides the capability to boot from GLAN. The options are Disabled and Enabled.

Onboard SCSI OPROM Configure

Enabling this option provides the capitally to boot from SCSI HDD. The options are Disabled and Enabled.

Default Primary Video Adapter

This item allows the user to select the Primary Video Adapter between two adapters instead of selecting among three or more adapters. The options are Other and

Onboard Video.

PCI Parity Error Forwarding

Enable this item to forward the PCI errors occurring behind P2P bridges to the South Bridge, so NMI can be asserted. The options are Enabled and Disabled.
