.Sh DESCRIPTION
|
|
|
|
|
The
|
|
|
|
|
.Nm
|
|
|
|
|
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
|
|
|
|
|
.Nx
|
|
|
|
|
.Em sparc ,
|
|
|
|
|
.Em sparc64
|
|
|
|
|
and
|
|
|
|
|
.Em sun3
|
|
|
|
|
ports. The architecture arguments above must be the bootable filesystem images
|
|
|
|
|
for the named architecture.
|
|
|
|
|
.Ar filesystem
|
|
|
|
|
is typically an iso9660 filesystem, see
|
|
|
|
|
.Xr mount_cd9660 8
|
|
|
|
|
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.
|
|
|
|
|
.Pp
|
|
|
|
|
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
|
|
|
|
|
.Nm
|
|
|
|
|
program will detect this and only write one copy of the boot image.
|
|
|
|
|
.Sh NOTES
|
|
|
|
|
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
|
|
|
|
|
.Pa .slicemapfile .
|
|
|
|
|
The format of this file is an
|
|
|
|
|
.Dq m
|
|
|
|
|
followed by a partition number, starting at offset 0, plus an architecture
|
|
|
|
|
identifier, such as
|
|
|
|
|
.Dq sun4c
|
|
|
|
|
or
|
|
|
|
|
.Dq sun4u .
|
|
|
|
|
The UltraSPARC uses the
|
|
|
|
|
.Dq sun4u
|
|
|
|
|
partition as it's boot partition. An example file that would be compatible with
|
|
|
|
|
older hardware would look like:
|
|
|
|
|
.Bd -literal
|
|
|
|
|
m 1 sun4
|
|
|
|
|
m 2 sun4c
|
|
|
|
|
m 3 sun4m
|
|
|
|
|
m 4 sun4d
|
|
|
|
|
m 5 sun4u
|
|
|
|
|
.Ed
|
|
|
|
|
.Pp
|
|
|
|
|
As such, to enable UltraSPARC booting, such a file must be present on the
|
|
|
|
|
image before
|
|
|
|
|
.Nm
|
|
|
|
|
adds bootable partitions to the image.
|
|
|
|
|
.Sh OPTIONS

|
|
which must be a multiple of 4. The default cylinder size is 640.
