Does anyone happen to know the organisation of a SunOS

Looking at the disklabel under Linux, I get the following:
| Disk /dev/sdb (Sun disk label): 15 heads, 131 sectors, 1701
| cylinders Units = cylinders of 1965 * 512 bytes

| Device Flag Start End Blocks Id System
| /dev/sdb1 0 48 47160 0 Empty
| /dev/sdb2 48 152 102180 0 Empty
| /dev/sdb3 0 1701 1671232+ 0 Empty
| /dev/sdb4 152 264 110040 0 Empty
| /dev/sdb7 264 1701 1411852+ 0 Empty
(ignoring the 'empty' - think that must be a bug in Linux fdisk as I
know there's a valid OS on the disk)
The ID of 0 and the "Empty" System label mean that fdisk doesn't
recognize the partition type, or more likely in this case, the ID field
in the partition/slice table at all. It doesn't refer to whether
there's data or filesystem on the slice.
However, obviously some space is taken up by the
partition table itself,
so the first (root) partition can't start at block zero. What I'm trying
to find out is the offset that it does actually start at, so that I can
mount the root partition from Linux.
Given the output of fdisk, I'm going to guess that your Linux kernel
doesn't support the SunOS 4 filesystem type. I've got an email out to a
friend who just installed on a 3/60 yesterday, so mayhap he can shedsome
light on this. Meantime, see if your kernel has "sysv" filesystem
support. I have a glimmer of a memory that that's what you'll need. ;)
