A corrupted ROM has to be followed by a system restore, either manual or automatic, depending on the level of intelligence you want to build into the hardware. I have seen scenarios where restore partition is in an unwritable location and there is a ROM in some safe location whose sole purpose is to restore from the protected partition.

Some MB already have that for last 64k. I think that having a 'you can never write this' bios image would be useful. The power fail scenario is a concern. ron -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios -- linuxbios mailing list [email protected] http://www.openbios.org/mailman/listinfo/linuxbios
