Legacy USB Support
This item determines if the BIOS should provide legacy support for USB devices
like the keyboard, mouse, and USB drive. This is a useful feature when using such
USB devices with operating systems that do not natively support USB (e.g.
Microsoft DOS or Windows NT).
Options: Enabled (Default) / Disabled / Auto
EHCI Hand-Off
This is a workaround for OSes without EHCI hand-off support. The EHCI ownership
change should be claimed by EHCI driver.
Options: Disabled (Default) / Enabled
Port 60/64 Emulation
This items enables I/O port 60h/64h emulation support. This should be enabled for
the complete USB keyboard legacy support for non-USB aware OSes.
Options: Enabled (Default) / Disabled
