Legacy USB Support
Legacy USB Support refers to USB mouse and keyboard sup-
port. Normally if this option is not enabled, any attached USB
mouse or USB keyboard will not become available until a USB
compatible operating system is fully booted with all USB driv-
ers loaded. When this option is enabled, any attached USB
mouse or USB keyboard can control the system even when
there are no USB drivers loaded on the system. Set this value
to enable or disable the Legacy USB Support.
X Disabled:
Set this value to prevent the use of any USB
device in DOS or during system boot.
