Whether BIOS will do it depends on implementation. Older systems had fixed boot device; newer ones probably can use next device in a list if first one fails. In both cases BIOS is not aware of Linux MD, so it does not matter whether you have single mirrored filesystem or two independent with the same content. To have full fault tolerance you would need to use hardware or firmware (fake) RAID for it. Actually your motherboard has fake RAID (even two as far as I can believe documentation); although it has its load of issues (starting with whether Linux and GRUB support it). _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
