    OK, but I think you are missing something in what I wrote. Once your tape
    backup is finished shutdown and install the IDE drives. Let it continue to
    boot your SCSI, which I presume also has the FreeBSD boot blocks
    installed. Use sysinstall on your current system to partition, format, and
    write boot blocks on the IDE drive(s). Mount the IDE drive(s) somewhere.
    Then you can use dump(8) piped into restore(8) directly from HD to HD.

    Once you think everything is on the IDE drive you can reboot and use F5
    when the SCSI disk "boots" to transfer the boot to the next drive in the
    BIOS chain. In this way the IDE drive should be able to "boot" off the
    SCSI drive. And once you have done this it will automatically do it again
    the next time. Only thing different is an extra 10 seconds or so waiting
    on the boot blocks on the SCSI drive to time out an "boot" the IDE drive
    where those boot blocks take another 10 seconds before transfering to
    either the next disk or to the selected OS.

    Once everything is working you can remove the SCSI drive but by chaining
    the boot process off the SCSI drive you don't have to remove it until you
    are good and ready.
