Hi,

the transaction error comes from the chipset configuration which
read-protects the ME region and has nothing to do with the flash
chip/your patch. Please search the mailing list archive and take a look
at the Documentation directory of flashrom regarding problems with the
locked ME region. Short answer: if you need to access the whole chip,
use an external programmer.
There is a hard coded override in some HP firmwares that might be worth
a try before that, try win, left arrow, right arrow (all at once i
think) as you turn on the laptop.

Thanks very much for showing your patch. No need to clean it up and
submit it again though, because we are working on our own version
already, see also

Sorry for not having it integrated already :)
