[parisc-linux] [REQUEST] PS/2 keyboard pinouts?

[Bob Radvanovsky]

I recently picked up about 30+ 712 workstations, some of which will be
converted to the Debian PA/Linux operating system.  I plan on importing
the clusting software, Eddie, over to Debian and turning about 12+ of
these 712 workstations into a gigantic Linux cluster.

Unfortunately, I don't have 30+ keyboards for all of these workstations. 
Having noticed that there was one gent (Andrew Shugg) who mentioned about
a PS/2 loopback connector, I have tried in desparation to find one premade
at several computer specialty shops, including Radio Shack.  I used to
remember when Radio Shack *did* have connectors that you could make your
own style or pinout connector.	Nowadays, you just get a snot-nosed kid
who states "Whatever we have is whatever we have, dude.......whatever."
(or something like that).  I *CANNOT* seem to find any PS/2 connectors
ONLY, and for that matter, cannot seem to find documentation on the
712/60, 712/80 and 712/100 workstations keyboard connector pinout, and
which pins will enable me to bypass the IPL problem of "no keyboard, no
bootup" problem.

Anyone got any ideas on where I can get (1) pin descriptions as to how to
bypass the "no keyboard, no bootup" problem on most of the HP
workstations, and (2) where I might be able to get some PS/2 connector to
make my own "headless" Linux cluster configuration.

Thanks in advance.

-ad nauseum: Also... anyone know of a *good* and *FREE* Linux clustering
software that is efficient enough to run?  So far, the best one that I can
find that is fairly configurable, and robust enough is "Eddie".  But the
only drawback is that it's interpretted and runs on a language called
"Erlang".  If anyone has had experience in this matter with HP
workstations, running Debian PA/Linux, under a clustering environment (in
a house that Jack built), I'd be very interested in hearing more...  ;)))

Well, we had the same problem here, when we wanted to 'clusterize' a=20
bunch of 712.

You can find a solution by switching your 712 to serial console,=20
following the instructions found at:
http://lists.parisc-linux.org/hypermail/parisc-linux/0423.html

You need HP/UX ISL for that.

If you don't have it, you can download the following lifimage:
http://cvs.parisc-linux.org/build-tools/uxbootlf

and then using bootp with it...

Here is the original posting for serial console on 712.

We should probably add this as a "How-To" someplace. Ideas on where?

I'll add this into the Console section of my HOWTO!

By the way, at this moment, you can read:


          How can I change the boot console to serial on a 712?

Unfortunately, you can't. Although 712s are configured for in-house HP 
development to use serial console, this configuration isn't supported in 
the field. You have to use a graphics console for 712s but if you really 
want it, you have a tip in the PA/Linux mailing list archive 
<http://lists.parisc-linux.org/pipermail/parisc-linux/1999-December/008117.html>. 
In fact, why will we use this beautiful 712 with serial console when you 
can have X!

( That part is from Debbie, I'll fix it )
