Asus P4S333 - Manual (Page 80)

4-16 Chapter 4: BIOS Setup
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]
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]
Refer to the CPU documentation before setting this field. A very high
core voltage may severely damage the CPU!
