I have a Toshiba Tecra 530CDT that won't boot at all - not from the hard disk or from a floppy. Apparently, one of the other techs had used this machine to swap a customers hard drive into for testing or something. Now that we've put the original hard drive back in, the machine won't boot.

When you press the power button the screen lights up and shows the memory test. After the memory test it just freezes - doesn't try to access the hard drive or floppy drive. Also, I can't get into the BIOS setup by holding down ESC. It just freezes at the same point.

Does anyone know if there's a key combination or other method of clearing the BIOS? I think maybe it's still looking for the other hard drive or something.
