It's worth noting that attempting to re-POST many (most?) laptops will fail miserably - the code simply isn't available after boot. Saving/restoring state with VBE code tends to be more reliable, but there are some machines that need POSTing. In the long run, it's the sort of thing that needs a hardware database, which effectively requires it to be in userspace. -- Matthew Garrett | mjg59@srcf.ucam.org - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
