Hi Ward,
Hi Philipp,
Out of curiosity, have you managed in-board flashing with flashrom?
well, yes and no => yes we used flashrom but up till now we only flashed the internal ROM of our BIOS Savior. Reading the original ROM image was possible too. But we did not really tested writing yet.
We have a couple of A8N-VM CSM boards, and while reading data with flashrom works, writing doesn't yet.
May it be possible that write-access is turned on and off via a gpio register of your superio? We've already had that case here. In our case we could turn on and off write access via a config option in orig. BIOS. Dumping registers twice with and without write access enabled we were able to track down the right gpio register.
Phil
