(USB 2.0).
USB 1.0 Controller
This field is used to enable or disable the Universal Host Controller Interface
(USB 1.0).
USB Operation Mode
This field is used to select the USB’s operation mode.
High Speed
If the USB device is a high speed device, it will operate in high speed mode.
If it is a full/low speed device, it will operate in full/low speed mode.
Full/Low Speed
Regardless of the speed of the USB device, it will always operate in full/low
speed mode.
USB Keyboard Function
Due to the limited space of the BIOS ROM, the support for legacy USB key-
board (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.
