CPU Vcore
This field displays the core voltage supplied to
the CPU. If you want to set it manually, always
refer to the CPU documentation. The pictures
shown here provide only examples of possible
Vcore ranges.
SDRAM Frequency (MHz) [Auto]
This feature tells the clock generator what frequency to send to the SDRAM.
The default setting [Auto] seeks to balance optimal performance with sta-
bility. The other options displayed in the popup menu vary according to the
CPU External Frequency. The first value is the external frequency multi-
plied by 3/4 and the second one equals the external frequency.
WARNING!
SDRAM Frequency higher than 100MHz is beyond the system
chipset specification and may cause your system to be unstable/hang up.
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 busi-
ness online or e-commerce. Otherwise, leave it to its default setting of [Dis-
abled] for greater anonymity when surfing the Internet. NOTE: This field
is available only when a Pentium III processor is installed 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. Configu-
ration 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 reserved
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]
