oops sorry that should be
"mount /dev/sda /mnt/a -o offset=622592,ro -t hfsplus"
I left off the equals sign
So I've got a macintosh SCSI drive that has an apple hfsplus partition I'd like to mount.
Let's say it's on /dev/sda
so I run "hexdump -C /dev/sda | less" and look at the output

what you're looking for is the apple_HFS part, and zero in on the PM line

^^^^^^^
This is the starting block of the partition = 04C0
so drop out of less and run "bc"
type "ibase=16" and hit enter (this will set you up in hexadecimal)
type "4C0*200" which is multiplying 4C0 by 200 (ie multiply by 512 bytes)
bc will tell you the result 622592
type "quit" to drop out of bc
before you proceed, "modprobe hfsplus" (works for me on knoppix 5.1)
now "mkdir /mnt/a"
then "mount /dev/sda /mnt/a -o offset 622592,ro -t hfsplus"
(I added the ro to make it read only)
and you should have the apple partition mounted.
Man do I love knoppix!

(my arrows didn't come through very well, I'll try underlines)
with regards to apple partitions
the start block of this partition is 00 00 04 c0
and the length of this partition is 00 61 6b 4f
but all you really need is the start block number to calculate the offset
