USB controller:
Enable the on-board Universal Serial Bus (USB V1.1 or V2.0) controller if you want
to connect a USB device to your system. Note that if this setting is disabled, you can
still temporarily use a USB keyboard during boot up so that you can enter BIOS and
enable this setting. If you pass the boot up stage without enabling this function, your
PS/2 keyboard will no longer work.
USB 2.0 Controller:
This entry is for disable/enable EHCI controller only. This BIOS itself may/may not
have high speed USB support. If the BIOS has high speed USB support built in, the
support will automatically be turned on when high speed device were attached.
USB Keyboard Support:
Select Enabled if your system uses an USB keyboard. If there is no USB keyboard,
select Disabled in this field.
Onboard LAN Device
Select Enabled if your system uses an on-board LAN device and vice versa.
