- combine filesystem for Sun Microsystems, Inc. computers for creating
bootable compact discs images.
program combines filesystem partitions for Sun Microsystems, Inc. computers into
an image suitable for writing to a compact disc, that will allow the disc
to be booted on the sun3, sun3x, sun4, sun4c, sun4m and sun4u platforms. This
hardware is supported by the
ports. The architecture arguments above must be the bootable filesystem images
for the named architecture.
is typically an iso9660 filesystem, see
for details, but can be any type as long as the first 512 bytes of the image are
not used. This image is modified, and the additional partitions added after this
partition, in order. If any architecture image is missing, that partition is
not used. If a disc with sun4 and sun4m support only was to be created, a dummy
image would need to be in place for sun4c.
If the same boot image maybe used for multiple architectures (as the NetBSD/sparc
ports for sun4, sun4c and sun4m allow), the same bootfile can be listed multiple
times on the command line. The
program will detect this and only write one copy of the boot image.
For the UltraSPARC line of computers, the PROM decodes a file in the first
partition of the CD-ROM, which must be an ISO9660 file-system, called
The format of this file is an
followed by a partition number, starting at offset 0, plus an architecture
identifier, such as
The UltraSPARC uses the
partition as its boot partition. An example file that would be compatible with
older hardware would look like:
m 1 sun4
m 2 sun4c
m 3 sun4m
m 4 sun4d
m 5 sun4u
As such, to enable UltraSPARC booting, such a file must be present on the
