Use the Legacy USB Support BIOS option to enable USB mouse and USB keyboard
support. Normally if this option is not enabled, any attached USB mouse or USB keyboard
does not become available until a USB compatible operating system is fully booted with all
USB drivers loaded. When this option is enabled, any attached USB mouse or USB
keyboard can control the system even when there is no USB driver loaded onto the
system.
