Need Help Restoring BIOS and MAC Address for HP ProDesk 600 G1 SFF

[ianasystems]

Hello,

I'm currently dealing with a BIOS corruption issue on my HP ProDesk 600 G1 SFF desktop PC.

After the BIOS got corrupted, my PC was showing no display, and I had to take it to a repair shop where the technician removed the BIOS chip from the motherboard and installed a BIOS I provided from a file I downloaded from the official HP website.

While the display issue was fixed and the system is powering up again, there's one major problem: the Ethernet MAC address is now showing as FF:FF:FF:FF:FF:FF, indicating that it's been wiped or corrupted as well.

I downloaded the latest BIOS update from HP's support website, using my PC's serial number to get the correct update file.

I extracted the BIOS bin file from the downloaded .exe using 7-Zip and gave it to the technician.

The technician flashed the BIOS, and while the system is working again, the MAC address is gone, showing the default FF:FF:FF:FF:FF:FF.

The technician mentioned that the BIOS file I gave him was an update file, not a BIOS dump, and that this might be the reason why the MAC address is missing.

PC : HP ProDesk 600 G1 Small Form Factor PC

PC Serial : 2UA5122MMV

PC Product ID : G5R58UT#ABA

Any help or advice would be greatly appreciated!

Thank you in advance!

Hello,

Thank you for your response.

I downloaded the BIOS from the HP website by entering my PC's serial number (HP ProDesk 600 G1 SFF - PC Serial : 2UA5122MMV) to get the correct BIOS version for my system.

I used 7-Zip to extract the contents, and inside, I found the .bin BIOS file.

What hoaca388 wanted you to post was the contents of the bios chip on your motherboard, using an SPI programmer. Try MAC address tools, if they don`t work you will have to buy a programmer.
