    Is that the PDC20270 chipset? What motherboard are you using (i.e., I guess
    you are using two IDE channels on the motherboard, so what chipset are you
    using there)? What kernel? Are you using ide-scsi at the same time? A DVD
    player? If so, how have you connected them? What is the biggest number of
    hard disks you are using? What size?

    I would like to try this out myself. Thank you---this is the first success
    story I have heard!
