USB Operation Mode

This field is used to select the USB’s operation mode. The options

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.
