Chapter 4: BIOS Setup
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 [1.850V]
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:
[1.100V] ...[1.850V]
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 Level 1 and Level 2 built-in cache.
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]
CAUTION! Refer to the CPU documentation before setting this field.
A very high core voltage may severely damage the CPU.
