Still, no luck making the console work; the 320H does

2) I cleaned the floppy drive (it wasn't that dirty), re-wrote the
four aix diagnostics floppies and tried them once more in service
mode.? The same thing happened: it reads the complete first disk
(apparently without error), but then it goes again to read the hard
drive and stalls in the same spot.? Does anybody have images of
diagnostics floppies that would be known to work in a 320H?
3) I now have AIX 4.3.3 install CDs.? Does the 320H expect a CDROM
drive to be at a specific SCSI ID?

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.
