CPU Level 2 Cache [Enabled]

These fields allow you to choose from the default [Enabled] or choose

[Disabled] to turn on or off the CPU Level 1 and Level 2 built-in cache.

Configuration options: [Disabled] [Enabled]

BIOS Update [Enabled]

This field functions as an update loader integrated into the BIOS to supply

the processor with the required data. When [Enabled], the BIOS loads the

update during system bootup. Configuration options: [Disabled] [Enabled]

PS/2 Mouse Function Control [Auto]

The default setting [Auto] allows the system to detect a PS/2 mouse at

startup. If a mouse is detected, the BIOS assigns IRQ12 to the PS/2

mouse. Otherwise, IRQ12 can be used for expansion cards. When you set

this field to [Enabled], BIOS reserves IRQ12, whether or not a PS/2 mouse

is detected at startup. Configuration options: [Enabled] [Auto]

USB Legacy Support [Auto]

This motherboard supports Universal Serial Bus (USB) devices. The

default of [Auto] allows the system to detect a USB device at startup. If

detected, the USB controller legacy mode is enabled. If not detected, the

USB controller legacy mode is disabled. When you set this field to

[Disabled], the USB controller legacy mode is disabled whether or not you

are using a USB device. Configuration options: [Disabled] [Enabled] [Auto]

OS/2 Onboard Memory > 64M [Disabled]

When using OS/2 operating systems with installed DRAM of greater than

64MB, you need to set this option to [Enabled]. Otherwise, leave to the

default setting [Disabled]. Configuration options: [Disabled] [Enabled]

CPU VCore Setting [Auto]

The [Manual] setting allows you to manually select the core voltage

supplied to the CPU(see next item). However, it is recommended that you

keep the default setting [Auto] to allow the system to automatically

determine the appropriate CPU core voltage.

CPU VCore [1.750V] (for Willamette), [1.500V] (for Northwood)

When the CPU VCore Setting parameter above is set to [Manual], the

CPU VCore item allows you to select a specific CPU core voltage.

Configuration options:

Pentium 4 (Willamette) [1.850V] [1.825V] [1.800V] [1.775V] [1.750V]

Pentium 4 (Northwood) [1.700V] [1.675V] [1.650V] [1.625V] [1.600V] [1.575V]

[1.550V] [1.525V] [1.500V]
