2.4.1 Chip Configuration

CPU VCore

When the CPU VCore Setting parameter above is set to [Manual], the
CPU VCore item allows you to select a specific CPU core voltage. This
field is not accessible when the CPU VCore Setting is set to [Auto].

CPU Level 1 Cache, CPU Level 2 Cache [Enabled]

These fields allow you to choose from the default [Enabled] or choose [Disabled] to
turn on or off the CPU Level 1 and Level 2 built-in cache. Configuration options:

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

reserves IRQ12, whether or not a PS/2 mouse is detected at startup. Configuration
options: [Enabled] [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]
