Here's one serial port ... Dino.

Here's another ... Lasi.

And the third ... Wax.

Umm.. you might want to get that checked out with your HP rep.

This is where we pick up the serial ports. We look for the Lasi first,
and we find it. Then we look for other kinds of serial ports and find
the Dino, then the Wax. I've not seen this behaviour before. Normally,
the unused serial port is the Dino one and it's placed somewhere our
bus walking code deliberately won't find it.
Instead, Dino's serial port is at 8/0/192 which seems wrong, I normally
see it at 8/0/3 (if attached) or 8/63 (if not).
I'm wondering about your firmware at this point. Can you take a look at
ftp://us-ffs.external.hp.com/firmware_patches/hp/cpu/PF_CB1X0061.txt
which tells you how to upgrade your firmware to 6.1 (the latest).
I'd be interested in knowing what your current firmware rev is too
(those instructions tell you how to find your current revision).
Note that you can boot the firmware from the LAN or a CD-ROM, you don't
need to create a tape.
