Okay....that's a new one. You will need to attempt to reflash that bios. Go to you mobo manufacturers web site and do a bios update or reflash the bios. MAke sure it is the bios flash for exactly the same mobo model or your mobo becomes a frisbee!!!
BTW. A P3 system? OMG, time to spend some money! Your system resides in the stone ages!!!
