NP, i just wanted to get sure you have received my last mail and
nothing momentous happened, because your replies were within days or
even hours before.

We have received your other message containing the read out bios image.
It sits in the moderation queue at the moment, because we can't publish
it (it is copyrighted). Thanks for taking the time to test! What we
actually wanted to see is the output that flashrom prints to screen (or
saves to a file when one specifies the log file option -o
But since you were able to read the BIOS file correctly the patch seems
to have worked at least to some extend. This is great news!
Nevertheless please send the verbose output of flashrom too.

The latter would be the last thing i would worry about, but especially
the service processors might interact with the BIOS and if an update
changes the protocol that they talk with each other, then this may lead
to unbootable machines...
It is probably possible to add support for the other device to flashrom
as well, but that would certainly not be a single line change and take
way more time to implement, even if IBM provides some documentation.
Without documentation it would probably be pretty much infeasible.
