Advanced Menu

System Performance [Normal Mode]

The default setting, [Normal Mode], seeks to balance optimal performance
with system stability. To optimize the performance of motherboard circuits
and the CPU, changing the setting to [Turbo Mode] tells the clock generator
to increase the frequency to the DDR RAM memory system. Configuration
options: [Normal Mode] [Turbo Mode]

Spread Spectrum Control [Enabled]

Leave on default setting. Spread spectrum typically reduces system electro-
magnetic interference (EMI) by 8dB to 10dB.

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]

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]

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]
