4. BIOS SETUP
System/SDRAM Frequency Ratio [Auto]
This field determines whether the memory clock frequency is set to be in
synchronous or asynchronous mode with respect to the system frequency.
The options displayed in the popup menu vary according to the System/
PCI Frequency (MHz).
CPU Vcore
In JumperFree mode, this field displays the core voltage
supplied to the CPU. If you want to set it manually, refer
to the CPU documentation. The picture shown here pro-
vides only an example of 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
[Disabled] for greater anonymity when surfing the Internet.
NOTE: This field is available only when a Pentium III processor is installed
in the 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]
