[parisc-linux] hardware newbie question...

[Stephen J de Vries]

I have a HP 712 that I'd purchased recently.

My question is:

Can I use a PC monitor, keyboard, and mouse to boot the thing up?  If so,
does the monitor have to be a multisync or something special?

In addition, HP-UX is on the hard drive but is locked down.  I was
thinking of buying an external CD drive and attempting to load debian
0.93.  Can anyone recommend a place to buy the CD drive that they have
dealt with?  I also have a network so I could attempt a network install
but I am not sure what minimum requirements I'd need to fulfill for that.
 Is my approach the right one?

Thanks for the advice...

OK for the PC monitor. Use 'Tab' at boot time to switch 712's resolution
NO for the PC keyboard (pc kbd is 75mA iirc, 712 is 500mA)
I don't know for the mouse.

You can unlock HP/UX pretty easily if the box isn't in secure mode.
Just stop the boot sequence and at the BOOT_ADMIN prompt type 'bo pri ipl'

Then answer 'y' to the 'interract with...' question, and then type (i 
don't know if we can say this here ;o)

hpux -iS

If the box is in secure mode there is a workaround:
Open it, unplug the HD, boot it, wait for timeout, and then deactivate 
the secure mode ;)
then reboot again.


You can definitly use network to install.
Check the palinux boot howto.
I recommend you use the latest version (still under review, that's why 
it's not yet available on tldp):

You will find all useful info there.

Hhmm. I have used two different PS/2 keyboards on a 712. So far nothing
unexpected has happened to either the box nor the keyboard... it works just
fine.

I've had a 712 (running HP-UX 10.20) with a multisync monitor (compaq,
before the merger) running verry well.

As I recal, the monitor should do a sync-on-green. If you don't get a proper
picture and have a monitor-cable connection with bnc connectors, try putting
the cable-sync on the monitor-green. This should give a sharp (bad collored)
picture.

For the mouse, the HP mouse that came with the device looks verry much like
a logitech mouse with a black logitech icon. 2 exceptions: the labels differ
and the logitech has a shorter cable. The same logitech with a colored icon
on top does not work. The mouse must be a native ps/2 mouse, not one that
can do serial-mousing too.

For the keyboard: try and see what you get. No experiences with alternates
here. As with the mouse, the keyboard must be native ps/2 since it does not
get any initialize command. An easy test here is that if the bootloader
finds a keyboard, it wil use that keyboard and the video-card for
bootconsole. If the keyboard is not found, the serial-port (9600-8-N) is
used for console.

Any scsi cd-rom that can do a 2K blocksize will do for booting. After boot,
there is no difference. HP-s are relabeled Toshiba's.

I have a 712 with the following peripherals:
- monitor from NCD
- mouse from IBM
- keyboard from Phillips
Works just fine.

What do you mean locked down?  Boot the thing single user and delete
the password.  At the "Press any key to interrupt boot" prompt stop the
boot.  Type BO <enter> interact with ISL? <y> <enter>.  Then at the isl
prompt type <hpux -is> <enter>.  That will get you into single user
mode.  Unless the system is setup in trusted mode you should be able to
get in and modify the /etc/passwd file.  The user name should come
first followed by the password that is encrypted within the colons
(ex:root:VDTGE$8757474:).  Delete the encrypted stuff but leave the
colons and save it.  Reboot it in multiuser mode and root shouldn't
have a password.

And even if those numbers meant something, 712 having 500mA available
and a keyboard pulling 75mA out of it would be perfectly fine. Now if
those were voltages or impedances, then you might want to match.

My SGI Granite says 12V 300mA max kb, 5V 15mA mouse
My HP C1429B says 200mA max, 12V 120mA (Whoa!) mouse
My Sun type4 says 5V 0.35A (sic) max both
ICL PS/2 says 0.3A

JFTR. ICBW, but I don't think so.

OK, just to put an end at this flow of mails, I was completely wrong 
about the keyboard and confused things with another problem we had in 
the past.

Therefore, I do confirm that 712 _can_ use any PC material. ;)

I hope that makes everybody happy :o)
