    In the SPARC architecture it is possible, and very often used, to have
    several boot disks. A sun server can boot from different disks on
    different SCSI channels. This is utilised in the large servers , the
    D240 boot-box for 3800-6800 servers has two disks on two SCSI channels
    that are SW-mirrored and provide redundant boot capability for this
    class of servers. The standard PC BIOS can only Boot from the first disk
    in the system, this is not the case for Sparc-servers.
