Can you tell me where the BIOS is located on Western Digital PCB Board 2060-701537-004 REV A. Your example picture does not represent where the BIOS Chip is located.

The PCB’s BIOS is integrated into the Main Controller IC. You should exchange the Main Controller IC to let the HDD be recognized. Move the Main Controller IC(the biggest chip on the board) is a complex job which need you have certain technique. Some electronics repair shop can do it.
