When I got my 68040 Cube upgrade kit it came with a motherboard and an
OD of NeXTstep 2.0, and a NeXT SIMM-puller tool. And some instructions
about the sequence in which to change things. All this information is
coming out of my occasionally fallible memory. But I'm sure that I was
using NS 2.0 and 2.1 long before I had a CD reader.

As I recall from experience upgrading a Cube from
a 68030 to a 68040
CPU board, NS 1.0a and earlier would not boot on the 68040. They were
written without knowledge of the future differences between a 68040 and
a 68030, which are significant at the system stack level. Just something
to think about.
Will 2.X boot on an '040? I knew that 1.X and below won't
work on the '040 but thought that it applied to 2.X as well. My main
reason for wanting to archive all the OD distributions that I have is
because it's quite easy to come up with a CD of 3.X but rarely do you
ever hear about someone with the earlier versions and they need to be
archived while there are still a few of the finicky optical drives
still functioning.

Thanks for correcting me on that. Unfortunately, I've still
not gotten NS 3.3 to reformat the DOS-formatted MO disks in my
Pinnacle Sierra, even with the disktab entries that James provided.
It appears to read them fine, as well as writing small text files to
them, but it won't initialize them either from the Worksapce or a
shell.

Ok, I've gotten the Pinnacle Micro Sierra 1.3GB MO drive to work using
the below disktab:
# Pinnacle Micro Sierra optical disk drive
# ECMA 512 byte/sector media
# Disktab generated by Jessica Hayden from SunOS /etc/format.dat entry
# and NextAnswers document 1533
PINNACLEOHD-1200|Pinnacle Sierra 1.2GB OHD|OHD-1200:\
:ty=removable_rw_scsi:nc#5359:nt#7:ns#31:ss#512:rm#3600:\
:fp#320:bp#256:ng#0:gs#0:ga#0:ao#0:\
:os=sdmach:z0#64:z1#192:ro=a:\
:pa#0:sa#1162903:ba#8192:fa#1024:ca#32:da#4096:ra#1:oa-space:\
ia:ta=4.3BSD:aa:
I initialized it with the following commands:
disk -t "OHD-1200" -i /dev/rsd1a
newfs -n -v /dev/rsd1a
I then ejected the disk and reinserted it. NS mounted it and reads
and writes to/from it just fine. It gives me nearly 600MB of space.
My next question would be what is the best way of making a bootable
copy of my internal MO disk to the Pinnacle MO? If I issue the
following command:
dd if=/dev/rod0a of=/dev/rsd1a
I get a read error on rod0a and dd aborts.
If I issue the command:
dd if=/dev/od0a of=/dev/sd1a
dd copies data from the internal MO to the external MO but doesn't
copy the data in the subdirectories. Any suggestions? Would dump be
better for this?
Thanks

Jeff,
I'm not familiar with Next so this is speaking from general unix experience,
but I think you need to copy the "whole disk" parition rather then the
"a"
partition on the OD. Assuming NextStep is using a BSD-style disk lable, which
it looks like it is, "dd if=/dev/od0c of=/dev/od1c" would do it. I use this
technique all the time on my linux machine to make archive copies of OS disks
and it works great; the linux example would be "dd if=/dev/hdc of=<file>",
and
then <file> can be burned back to a CD later...

Actually I got it working with 'dump' piped through
'restore', thanks to the suggestion from another list member. I was
able to dump two of the NeXT optical disks to the Pinnacle, for
archiving, and then dump one of them to an external 1GB hard disk. I
have some fstab issues to work out with the copy though as it insists
on booting into single-user mode looking for the optical disk in the
internal drive. It gave me the same thing when I attempted to boot
from the Pinnacle with it set to SCSI ID#0. I'm
getting there, even
if it is slowly. I still plan on messing with dd some more to
try
and create some images of the disks though. I'm hoping that since it
has the dust filter installed that the optical drive in my Dimension
Cube holds up long enough to finish transferring all of them.
Since it doesn't have an internal boot drive, just a 40MB
swapdrive at SCSI ID#6, I'm doing the test boots on my '030 Cube but
using my extra '040 mainboard. I loaded the '030 mainboard with RAM
and started to boot it and found out that it was set to boot over
ethernet and that it had a hardware password set! Hopefully by the
time I get home the mainboard will have forgotten it's hardware
settings since it's been sitting with the battery out overnight.

Well it worked....I changed the fstab file on the hard disk
that I had copied NextStep 2.0 onto, off of the copy I had made to
the Pinnacle MO, and it booted right up! I also put the '030
mainboard back into the 2nd Cube and booted it off of the NS 2.0 hard
disk install and it worked as well. Even the NeXT 'Guided Tour' was
kind of interesting. Now I'm off to start copying the other distro
disks to the Pinnacle MO.

Most excellent! Congratulations.
