Yes, I'll try to do it later today.
Dump must be charged on Medusa ROM, and dumpped on 8MB chip soldered on A4064 adapter.
Medusa cannot process the file directly on its ROM yet.
I suggested this to Harald some time ago. He's planning to add this option in the future.
1) remove bios from board
2) copy bios to bin image using TL866CS reader (via windows or linux)
3) copy clean ME region file for the board to a new file
4) modify new file with sections of the old bios (ie, starting from the "ssn" string)
5) write newly created bin ( clean ME + old data copied across)
6) solder chip to the mainboard
Do you only swap generic clean ME into backup BIOS?
Settings of the new (clean) ME region should be configured according with the actual board you work with.
If you have a known good clean ME BIOS, you can just swap Fsys region from the actual board.
This way you build a new clean ME BIOS with the actual SSN of your board.
If you only change SSN into Fsys region, then fix checksum is required.
And Medusa allows to do all these things onboard.
Please try the first one, it's your original Bios with ME fixed in case it was corrupted.
The second one is a new clean bios with all your FSYS info transfered into.
Both should work, but i prefere always to try the first one in case there is differences I am not aware of. But never had issues for both.
Let me know if it works, unfortunately I didn?t tested them.
