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
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]

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]

This function is supported only by USB 1.1 ports 1 and 2 (rear panel, and USB
5 and 6 (internal USB 1.1 header).

[Disabled]. Configuration options: [Disabled] [Enabled]
