Don't have a jumper (must have lost it), shorting those pins with such methods can be risky...

its the same thing as a jumper, they both basically just short out to clear the cmos.

well only other way is buy a p/s2 keyboard or adapter from usb to p/s2.

I use a screwdriver to short pins in order to turn on my computer that is on a test bench.

I'll try that tomorrow, thanks. Does it usually work? I hear Gigabyte motherboards can be finicky and reload the last known BIOS settings.

Already did that. BIOS just loads last known settings - incidentally, the setting which has USB ports disabled.

It's almost impossible to reload settings when you reset it via jumpers or the battery. If there's no power going to BIOS chips then I can't see how they can retain their memory.

Reset them by shorting the pins while EVERY source of power is unconnected.

Odd thing is, when I reseat the battery and reboot the computer, the BIOS would tell me that the CMOS is corrupted and presents me with a menu with the last known settings. Unfortunately, I can't seem to use my USB keyboard to select the "set to Default settings" option. After thirty seconds, it defaults to the last known settings.

I've heard that Gigabyte also stores BIOS settings inside hidden partitions on hard drives and loads them when necessary - is that true?

I'm guessing it reads the settings from the other BIOS and reloads them.

I'll do the shorting the pins trick with a screwdriver tomorrow, but I'm not terrible optimistic. Granted, this was my fault to begin with. I might need to purchase a USB to PS/2 adapter, but I hear that not all such adapters are compatible with all USB keyboards (mine being a Logitech K800).

USB to PS2 adapters do not usually work with wireless keyboards.

I have a couple and the K800 on another system. I'll give it a try for you and see if it works. The K800 uses a wireless unifying reciever that does not play nice through a PS/2 port.

You would almost be better off buying a $5 or $6 crappy ps/2 keyboard. I keep one as a backup when strange things happen (and for old systems).
