ASUS P4SE Motherboard 2-13
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.
