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. This field is not accessible when the CPU VCore Setting is set to [Auto]. Configuration options:

Pentium 4

(Willamette)

[1.750V] [1.775V]

[1.800V]

[1.825V] [1.850V]

Pentium 4

(Northwood)

[1.500V] [1.525V]

[1.550V]

[1.575V] [1.600V]

 

 

[1.625V] [1.650V]

[1.675V]

[1.700V]

Refer to the CPU documentation before setting this field. A very high core voltage may severely damage the CPU!

CPU Level 1 Cache, 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 set to [Enabled], the BIOS loads the update on all processors 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]
