Memory Frequency [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 Frequency
(MHz). Configuration options: [Auto] [200MHz] [266MHz] [333MHz] [400MHz]

turn on or off the CPU Level 2 built-in cache.

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]
[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
