USB keyboard not active during boot....

I think I may have caused myself a bootload of trouble.  I was in my bios to fix a problem with the boot order of my disk drives and I noticed a selection to enable legacy usb support.  Thinking I did not want legacy support I unchecked this item.   I saved the settings and booted up...  I have since come to find out by unchecking that item I was disabling usb support during boot and now I cannot get into my bios since all my keyboards are USB.  In fact, my computer does not even have a ps/2 port so I cannot hook up a ps/2 keyboard.

Is there any program available that will cause the computer to boot into bios setup?

Is there anyway other than jumpering the motherboard to cause the system to enter bios setup during boot?
