  With difficulty. Many parts of the installation process assume that
  you're installing IRIX onto your system disk (SCSI ID 1). Just fiddle
  with SCSI ID switches and/or move disks around to make the disk onto
  which you want to install IRIX the system disk for the duration of
  the installation.

  Furthermore, IRIX has many hardware dependencies, so you should only
  move system disks between absolutely identical machines. If you want
  to make a system disk for a machine without a network connection,
  CD-ROM or tape drive, the easiest and safest way is to borrow another
  CD-ROM or tape drive.

  If you want to try anyway, Justin Mason <> reports that
  the following works under IRIX 5.1.1:

  Set up the disk, e.g. with SCSI id 4, fx a generic "[bo]otable"
  partition setup onto it, and mkfs the partitions. Copy sash, etc.
  from your system disk to the new disk with dvhtool. Boot up the
  miniroot as usual, go into inst, choose "admin" from the menu and do
  the following, replacing SCSI IDs and partition numbers as

    umount /root
    umount /root/usr
    mount /dev/dsk/dks0d4s0 /root
    mount /dev/dsk/dks0d4s6 /root/usr
    mount				# Just to check
    return				# Go back to main inst menu

  Then install as you like.
