There is no elegant way to do this on Irix, so you need a blank disk with
nothing important on it. Note, this overwrites the *whole* disk, so
use wisely.
# dd if=image.iso of=/dev/rdsk/dks0d2vol bs=16384
/dev/rdsk/dks0d2vol is obviously replaced with the drive you want to
overwrite. Once written, the partitions can be mounted with normal
tools.
EFS images are a normal disk image, including partitions written to a CD.
