This item lets you enable or disable the USB
keyboard driver within the onboard BIOS. The
keyboard driver simulates legacy keyboard command
and let you use USB keyboard during POST or after
boot if you don't have USB driver in the operating
system.
Caution: You can not use both USB driver
and USB legacy keyboard at the same time.
Disable "USB Legacy Support" if you have
USB driver in the operating system.
USB device is default to use PCI INTD#, the same as
PCI slot4. If you installed PCI card on slot4 and
require to use INTD#, set this item to Yes. The USB
device will then be disabled.
Note: Normally, PCI VGA does not need PCI
interrupt, you may put PCI VGA on slot4.
Setting this parameter to Enabled allows you to
connect your floppy disk drives to the onboard floppy
disk connector instead of a separate controller card.
Change the setting to Disabled if you want to use a
separate controller card.
