I have made some progress here. I imaged the original hard drive and by
searching this image in bvi I found that the
original AIX version in it is AIX 3.1. I found another set of
BOSboot diskettes on the net, but for AIX 3.2, and some
advice about not running the getrootfs script in the maintenance shell
of V3.2 in a V3.1 system. I was able to boot the
maintenance shell off these diskettes (Finally the console came up! My
console cable and my MODU serial connector
kludge were fine). I figured a way to mount the hard drive's partitions
in this ramdisk-based maintenance shell and
get around the very limited commands in this shell (no ed, ex, vi, ls,
or many others) to modify /etc/security/passwd,
/etc/inittab to something basic. I found that there is no /sbin or
/usr/sbin in this hard drive, but then I noticed that
most of the commands that usually reside in those directories were to be
found in /etc . With one major omission: there
is no /etc/mount anywhere to be found. I found that the programs in the
hard drive bomb immediately ("Killed") in
the V3.2 maintenance shell, so I believe that they are
binary-incompatible. After all of this, I was able to boot
(partiallly, see below) the machine and log in the root account. But,
since the mount command is missing,
the file systems in /etc/filesystems were not mounted, so I do not have
access to /usr . I copied the /etc/mount
command in the V3.2 maintenance shell to /etc/mount in the hard drive,
but this command also bombs under V 3.1.
So, I need a copy of the /etc/mount binary from AIX V3.1 . I think that
I can mount a DOS floppy and transfer
this binary that way (this system does not have a network card). Or, I
can copy the /usr/bin/uudecode binary from
the /usr partition to /etc/uudecode in the root partition while in the
maintenance shell and then use that to get the
binary while under V3.1 .
So, does anybody have access to an AIX V3.1 /etc/mount binary?
My inittab generates some errors, all of which seem to be attributable
to the fact that /usr is not mounted.
Eventually, I will probably install AIX 4.3.3, but first I need to get
more SD2SCSI devices, so that will take a while.
