Seagate pcb's BIOS chip:

Most HDD boards have the unique BIOS(ROM or NVRAM chip) which includes the unique data to access the HDD system area. If the BIOS information is not compatible with your HDD, there is no way to read the HDD's data. Because of this, we should move the original PCB's BIOS to the replacement PCB. BIOS CHIP SWAPPING IS A MUST.
