Hello Greg,

as i briefly mentioned in my previous mail, locked regions are a bit
tricky and flashrom can not deal with them (i.e. unlock them). We are
working on understanding how to unlock them, but intel does not provide
us any documentation so please do not expect a solution soon.

Since the SMBIOS information indicates that your company is assembling
the firmware itself, maybe you could arrange that the ME region is not
locked? As far as we know this is not a problem in everyday operation
or for an update with flashrom (contrary to the scaring intel
documentation that tries to convince you from the opposite).

Can you explain why doing a read operation failed? I expected that reads would work and writes would fail.

Thanks,
Greg
