USB Operation Mode
This field is used to select the USB’s operation mode. The options
are Full/Low Speed and High Speed.
USB Keyboard Support
Due to the limited space of the BIOS ROM, the support for legacy
USB mouse (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 mouse is not available and you need
to use a USB mouse to install Windows (installation is performed in
DOS mode) or run any program under DOS, set this field to
Enabled.
