RDRAM/FSB 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 VCore Setting [Auto]
This field determines if the CPU Vcore is automatically scaled or set manually
by the user. The default for this field is [Auto], so the CPU vcore voltage is
set for maximum performance without stressing the CPU. Configuration
options: [Manual] [Auto]
CPU VCore [Auto]
When the CPU VCore Setting parameter is set to [Manual], this item allows
you to select a specific CPU core voltage. This field is not accessible when
the CPU VCore Setting parameter is set to [Auto]. Configuration options:
[Manual] [Auto]
CPU Level 1 / 2 Cache [Enabled]
These fields allow 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]
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 [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]
