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.
EHCI Hand-Off
Enable this field when using operating systems without the EHCI hand-off
support.
