Unfortunately, flashing the modified image back to the board fails
during the verify step. The same thing happens when I attempt to write
the original BIOS back to the board, so I'm stuck with a presumably
bricked board. Below is (I hope) all the relevant information you need.
I've also attached the original and modified BIOS images.
please don't attach proprietary software images, you are probably not
allowed to. (And we actually have a 256KiB limit on the mailing list,
I guess your message was forwarded by accident.)

That chip is a 1.8V part, I hope you are using a voltage shifter?

Directly attaching a programmer via a Pomona clip is often done, though
generally not a good idea unless you know the board design. It's hard
to tell what is really going on on the board, what other chips are
involved, etc. You can even harm the board if you attach voltage via

It could be something on the mainboard interfering, but it could also
just be a flaky connection. First step is always to test the reliability
of the connection, e.g. dump the whole chip once and then verify the
result multiple times.
A little brute force might also help, generally discouraged but as you
have started anyway: You can try again and again and see if the "failed
byte count" decreases. If it does, you can try again until everything
Hope that helps,
