Legacy USB Support
Due to the limited space of the BIOS ROM, the support for legacy USB
keyboard (in DOS mode) is by default set to Disabled. With more BIOS ROM
space available, it will be able to support more advanced features as well as
provide compatibility to a wide variety of peripheral devices.
If a PS/2 keyboard is not available and you need to use a USB keyboard to
install Windows (installation is performed in DOS mode) or run any program
under DOS, set this field to Enabled.
Port 64/60 Emulation
Enables I/O port 60h/64h emulation support. This should be enabled for the
complete USB keyboard legacy support for non-USB aware OSes.
USB 2.0 Controller Mode
Sets the USB 2.0 controller mode to HiSpeed (480 Mbps) or FullSpeed
(12 Mbps).
BIOS EHCI Hand-Off
Enable this field when using operating systems without the EHCI handoff
support.
Hotplug USB FDD Support
Enables support for USB FDD hot plug.
USB Mass Storage Device Configuration
Configuration for USB mass storage class devices.
