CPU/Memory 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 that appear in the popup menu vary according to the CPU/PCI
Frequency (MHz). Configuration options: [Auto] [1:1] [3:4] [3:5] [4:5]
(The configuration options vary depending on the CPU frequency.)
CPU Level 2 Cache [Enabled]
This field allows you to choose from the default of [Enabled] or choose
[Disabled] to turn on or off the CPU Level 1 and Level 2 built-in cache.
Configuration options: [Disabled] [Enabled]
CPU Vcore Setting [Auto]
This field sets the option to change the CPU core voltage. The default
setting is designed to maintain the safest voltage for the CPU. Resetting
the field to [Manual] enables precise voltage selection. Configuration
options: [Auto] [Manual]
CPU Vcore [1.750V]
This field is only available when the CPU Vcore Setting is set to [Manual].
The default Vcore is 1.75 volts. Configuration options: [1.750V] [1.775V]
[1.800V] [1.825V] [1.850V]
BIOS Update [Enabled]
This field functions as an update loader integrated into the BIOS to supply
the processor with the required data. When set to [Enabled], the BIOS
loads the update on all processors 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]
