21.3.2
USB Port 64/60 Emulation
This BIOS configurable feature enables emulation of I/O ports 64h and 60h allowing for
full PS/2 legacy support for USB keyboards and mice. It is also useful in providing USB
keyboard and mouse support in operating systems which does not natively support
USB.
When enabled, the BIOS emulates I/O ports 64h and 60h for the USB keyboard and
mouse. This enables PS/2 functionality like keyboard lock, password setting, and scan
code selection. When disabled, the BIOS does not emulate I/O ports 64h and 60h for
the USB keyboard and mouse.
