Re: [flashrom] Help: unable to upgrade bios

[Raghuramchary Jallipalli]

Hello Stefan,
Do you have any plans to support the laptops with QM67 chipset and AT25DF321A, AT25DF641A flashchips, to upgrade the bios gracefully? If yes, can you please give us the timeline.

Appreciate your help.

Thanks,
Raghu

Hello Raghu!

The answer to your question can be found in the manpage of flashrom.
The warning is set up for a reason (explained in the warning itself,
the linked webpage and also in the manpage). If you understand and
accept the possible consequences go ahead with the procedure in the
manpage.

Most probably it will not work even then, because the QM67 chipset can
is probably locked down, which we can not unlock yet. We could verify
that with a verbose log (after following the manpage). It would also be
interesting to know which laptop that is (then).

This procedure is not to annoy you, but to ensure that users do not
take the warning lightly and look at it more closely.
