About Hard Drive PCB Components:
BIOS: All of the 8pins (4 pins on each sides) with 25P05VP,25P10VP,25F512,25F1024,25F1024AN,SST25VF512,SST25VF010, etc. are the BIOS. It is easy to be found, because there are not many 8pins chips on the PCB.
Main Controller IC: If there is no matching 8pins BIOS chip on the PCB, it means the BIOS is integrated on the Main Controller IC. It is more complex to exchange the Main Controller IC than exchange the BIOS. If you should do, please do several test on the HDD’s PCBs which don’t have the important data.
About Firmware Transfer Tool & Steps:
HDD PCB Firmware Transfer Tools:
- Hot air rework station;
- T6/T8 Screwdriver(available on HDDZone.com product page);
- Tweezers;
Steps to transfer firmware on the PCB:
