Haven't tried it on factory.bin. Will let you know.

i945 doesn't have ME/AMT, as far as I know.

I remember (very vaguely) reading about the fact that i945 can have AMT,
but that the "BIOS flash" has to be partitioned to allow that.

I'm also unsure where would the AMT run, maybe in the NIC? In that case
it may be able to fetch its firmware from a flash directly connected to
the NIC, and it may have nothing to do with the BIOS flash, I really
can't remember, sorry.

In any case, all the lenovo i945 laptops that we have in coreboot are
not setup for AMT.

I should try to find the datasheets I was talking about, and document
that since that question comes up way too often.

Is it possible that NIC is left on due to Wake on LAN feature?
Is it enabled at all in your case?
