Description
This BIOS feature enables or disables the
motherboard's onboard USB controller.
It is recommend that you enable this feature so
that you can use the onboard USB controller to
communicate with your USB devices.
If you disable this feature, the USB controller will
be disabled and you will not be able to use it to
communicate with any USB device. This frees up
an IRQ for other devices to use. This is useful
when you have many devices that cannot share
IRQs.
This BIOS feature enables or disables the
motherboard's onboard USB 2.0 controller.
This BIOS feature determines if support for the
USB keyboard should be provided by the
operating system or the BIOS. Therefore, it will
only affect those who are using USB keyboards.
If your operating system offers native support for
USB keyboards, you should select the OS
option. This will provide much greater
functionality. However, if you are using DOS or
operating systems that do not offer support for
USB keyboards, then using the OS option will
essentially disable the keyboard as these
operating systems cannot 'detect' or work with
USB keyboards.
