normally that should not cause any problems as it just tries to read the
flash chip content. flashrom is very careful to not break anything, so
it is very unlikely that the problem was caused by this command.

You have to be very specific.

1. What Linux distribution did your friend use? What version of
flashrom? The packaged one?

2. What did your friend exactly do? Did he see any error messages from
flashrom. I guess he just shut the system down?

A similar board seems to be supported [1]. So the problem is even
stranger.

If it was really deleted/erased or a bad image was flashed, then you
have to reprogram the chip either with a flash chip programmer. One way
is to find a motherboard where the chip fits and reprogram it there by
hot swapping it. If that is not possible ask around in your local hacker
community or find a shop which does it.

I wish you good luck with recovery! You should also join the #flashrom
IRC channel on irc.freenode.net.


Thanks,

Paul
