Legacy USB A mechanism that makes the computer confirm the USB (Î page 173) device after the
computer’s power is turned on and before Windows starts up. Since MS-DOS was developed
before the origin of USB technology, the ability to recognize USB devices was not included.
However, if the computer is compatible with Legacy USB, it will recognize USB devices.
z In this computer, the Setup Utility includes the item [Legacy USB Support]. If this item is set
to [Enable], the computer will recognize a USB keyboard or USB floppy disk drive before
Windows starts up.
