I found this rather confusing. I'm not clear what you are trying to do. (1) Have you tried changing your present grub.conf to say eg "root (hd1,0)" ? (2) If you actually want the BIOS to look at hdb (= hd1) it will look at the MBR on that disk, so you would have to install grub there if you want to use grub. What have you got against using grub-install? I'd recommend running "grub-install --recheck" to make sure it sees the hard disks as you do. But I've probably misunderstood what you are trying to do. -- Timothy Murphy e-mail (<80k only): tim /at/ birdsnest.maths.tcd.ie tel: +353-86-2336090, +353-1-2842366 s-mail: School of Mathematics, Trinity College, Dublin 2, Ireland
