Thanks, committed in r591.

Just to be really sure exerything works ok...

Please do './flashrom -r empty.dd' and them 'hexdump -C empty.dd', which
should return only 0xff bytes.

And here, please try to write an image consisting of random bytes
(if you can recover in case things go wrong), then verify it with -v:

dd if=/dev/urandom of=rnd.dd bs=1024c count=512
./flashrom -w rnd.dd
./flashrom -v rnd.dd

If this verifies OK we can be sure that all works fine. You can then
write your proper BIOS image back to the chip.


Thanks, Uwe.
