As OtheHill stated, you need to unplug the power cord before you attempt to reset the BIOS. Removing the battery generally isn't necessary. Almost all boards have a clear CMOS jumper that is usually in the general vicinity of the battery. Just unplug the cord, move the jumper to the clear poisition, wait a few seconds, then move it back again. That's all there is to it.
