Finally booted my C180 with the help of members on this list. The next
problem which i should have expected, but did'nt... now i am presented with

It is to reboot in single user mode, edit the /etc/password file (remove the
password field for 'root' and optionally an other acount will do) and then login
with root or the other account.

If you cannot login with root, use the other account and `su` to root. Now force
a new password (with `password`) and off you go.

Or just install linux on it: http://www.openpa.net/linux.html.

Well, You can boot in single user mode by interrupting the boot process (see
the message like "Booting in xxx seconds. Press any key to interrupt". After
that You're in the PROM (Firmware, somewhat similar to a PC's BIOS). Type
"boot". You'll be asked "interact with IPL (Y/N)?", answer "YES". The
machine boots into the first boot stage, and You'll end up in the IPL
(Initial Program Loader) command line. Enter "hpux -is", and the machine
should boot in single user mode...

My other recommendation would be to get one of the HP-UX CD Sets that are
often listed on ebay, preferrably HP-UX 11i. Makes it easier to reinstall,
and You can be sure to have an installation that isn't messed up somehow...

Or You can install Linux, but then I see no reason to waste such a nice
workstation with an OS that runs best on x86 and doesn't support most
hardware for these machines. And there should be nothing that You miss if
running HP-UX instead of Linux...

I did all that and it worked exactly as you said...but what's the problem?
now i am at the point where it says "warning you are superuser" and a prompt
"#" to enter a command. I aparently gave the impression that I know
something about HP-UX when in fact I know zilk about it. Is there some
website that may have a list of general commands that i can find useful. I
was hoping to edit the /etc/password file to remove the password as another
suggested. I just want to get back into the graphical mode where i will have
some measure of comfort

I do have the CDs for it. I believe it is version 10 point something, but
the unit does not have a CD-ROM drive so i am not ready to explore that
option yet, since i have to search for a compatible drive

I agree with that. It would be a waste since i have several x86 machine
available to run Linux. I definately want to keep HP-UX since it gives me an
opportunity to learn

the command to change the password is passwd, use /sbin/passwd to run the
command. The file format for /etc/passwd is found by doing "man 4 passwd",
of course without the ". A word of caution. If the system was configured
with LVM the filesystems for commands and shared libraries is not mounted
at the superuser prompt in single user mode. Do a /etc/bcheckrc and then
a mountall. Once you fix the password do an init 4 to get back to the
graphical mode.

There a several books out there for HP-UX. Once your system is up and you
can run commands, try uname -a and you will see what version OS you have.
By the way, 10.something is obsolete now. If you can find some 11.x media
you might consider upgrading.

That's good! At least You're in the system...

Understandable...

Ok, to change the root password enter "passwd". Then You'll be asked for a
new password. You also can just slap <enter> to have none password (not a
problem if the machine is not connected to the internet or a big company
LAN). If You've done that enter "reboot" to have the system restarted. It
comes up with the graphical login prompt where You now should be able to
login as "root".

As to the commands, have a loo at http://www.docs.hp.com where You can find
the manuals for HP-UX. For most administrative tasks You only have to
remember the command "sam" (System Administration Manager) which is a
menu-driven tool to do most common administration tasks. It works both under
the graphical environment (CDE) and also on the text-mode command line.

Well, HP-UX 10.20 is obsolete for some time now. It's 32bit only (HP-UX 11.x
is 64bit, and Your C180 is a 64bit system), there is no support (i.e.
patches etc) for it, and it also has some glitches that can drive You crazy.
I'd really recommend to get a HP-UX 11i CD Kit for Your system...

Well, any standard SCSI drive should work.

Good idea. However, even for learning I really recommend to get HP-UX 11i
(or at least 11.0) instead. With that You also can use the software
downloadable from http://www.software.hp.com or http://hp.ux.asknet.de

The only CD drives that will work reliably are the Toshiba's, find an
old 4x SCSI one. Plextors work too, some. You have to have a drive that
has variable block size.

Nope. What You say was valid for some old 700 series machines (AFAIR 715
etc). Even the older C-Class machines boot fine from any modern CDROM drive.
You don't need to set it to 512 byte mode as this is done by the systems'
firmware. If You open a Cxxx or Bxxx with CDROM You'll recognize that there
is no jumper set to switch to 512 byte mode.

I used several CDROMs (from old and new Toshiba, some Panasonic/Matsushita
drives, TEACs, NECs and others) on different Cxxx machines without any
problem. Of course it's possible that a certain CDROM model might refuse the
byte mode switch command but in generall the masses of SCSI drives works
just fine.

Ahhh. didn't know that, all the Cxxx that I have dealt with have
internal CD's so haven't had to deal with it. Must be related to the
C720 SCSI driver in the 7's, probably the same reason 11.x is
unsupported on them, right?

I don't know about the C720 SCSI driver but the issue with the 512byte mode
jumper of older 700 series is (like on most other UNIX workstations of that
time) just a firmware issue. The old firmware was only able to boot from
disk devices which generally have 512bytes/sector. A standard ISO CDROM is
2048bytes/sector so the firmware could not handle them. To resolve this some
CDROMs got a jumper to force them to 512byte sector size so that the
firmware sees the CDROM just as another disk device it can use to boot from.

On more modern workstations (from HP it's the Bxxx/Cxxx/Jxxx and when I
remember right also some of the newer 700's) the firmware is able to set the
512 byte mode via a SCSI command. And the somewhat current systems (i.e.
Bxxxx/C3xxx/Jxxxx) alsow boot from 2048byte devices just fine.

BTW: the only UNIX systems that never required a CDROM with 512byte mode
jumper to boot from are the IBM RS/6000's. Even my old 7012-320H (1990
vintage) boots just fine from any generic SCSI CDROM ;-)
