1) write down all your scsi device numbers in a column, starting
with scsi id 0, e.g.
SCSI ID Partition type Device Name
0 MacOS sd0
1 A/UX sd1
4 MacBSD sd2
5 A/UX sd3
2) starting with the first device in the list, number it sd0. The
next sd1, the next sd2, and so on. Note that sd3 is scsi id 4..
3) for any scsi id with an A/UX filesystem (even MacBSD), if it has
Root or just root, that partition is "a". If it has a separate Usr
partition, it's "g".
4) now, assuming from the list above I am booting into MacBSD on
scsi id 4, and the first A/UX partition has a separate Root and Usr
partition (sd1a and sd1g), I could mount the partitions like this:
mount -u / (in case you booted single-user or fstab isn't setup)
mount /dev/sd1a /mnt
mount /dev/sd1g /mnt2
I've only ever mounted an A/UX filesystem with a single Root&Usr
partition (for A/UX 2.0.1 and 3.0). But if A/UX has a separate Usr
partition, the above should work.
Try it, and let us know what you find out.
Oh, if there are no entries in /dev for the partion you want to mount
(e.g. sd3a doesn't exist), you will have to:
MAKEDEV /dev/sd3a 4 24
MAKEDEV /dev/sd3b 4 25
MAKEDEV /dev/sd3h 4 31
MAKEDEV /dev/rsd3a 13 24
MAKEDEV /dev/rsd3b 13 25
Corrections to the above example are welcome.
