If there's a write protection in place which blocks the internal programmer, then you could get the external programmer like a USB CH341A (preferably a green PCB) to access a chip with a BIOS firmware - directly. If your BIOS chip is inside the DIP8 socket, then you'd need a DIP8 / PLCC remover to safely extract it from a socket; if it's SOIC8 soldered on the motherboard, you'd need a SOIC8 test clip to connect a programmer directly to this chip without desoldering it.
