4. BIOS SETUP

Advanced Menu

CPU Vcore

In JumperFree mode, this field displays the core voltage sup-

plied to the CPU. If you want to set it manually, always refer

to the CPU documentation. The picture shown here provides

only an example of possible Vcore ranges.

CPU Level 1 Cache, CPU Level 2 Cache [Enabled]

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

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

Configuration options: [Disabled] [Enabled]

CPU Level 2 Cache ECC Check [Disabled]

This function controls the ECC capability in the CPU level 2 cache. Con-

figuration options: [Disabled] [Enabled]

Processor Serial Number [Disabled]

The Processor Serial Number is a unique number that is added to every

Pentium III processor to help verify the identity of the user across the

Internet. Set this field to [Enabled] when you need increased security for

doing business online or e-commerce. Otherwise, leave it to its default

setting of [Disabled] for greater anonymity when surfing the Internet.

NOTE: This field is available only when a Pentium III processor is in-

stalled in your system.

BIOS Update [Enabled]

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

processor with the required data. In the default position of [Enabled], the

BIOS will load the update on all processors during system bootup. Con-

figuration options: [Disabled] [Enabled]

PS/2 Mouse Function Control [Auto]

The default of [Auto] allows the system to detect a PS/2 mouse on startup.

If detected, IRQ12 will be used for the PS/2 mouse. IRQ12 will be re-

served for expansion cards only if a PS/2 mouse is not detected. [Enabled]

will always reserve IRQ12, whether on startup a PS/2 mouse is detected or

not. Configuration options: [Enabled] [Auto]

USB Legacy Support [Auto]

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

fault of [Auto] allows the system to detect a USB device on startup. If

detected, USB controller legacy mode will be enabled. If not detected, USB

controller legacy mode will be disabled. When this field is set to [Dis-

abled], USB controller legacy mode is disabled no matter whether you are

using a USB device or not. 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 this on

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