[parisc-linux] PCI card in C160

[Kurt Fitzner]

I am trying to put an Ethernet card into my new (to me) C160 without any
success.  Any time I put a PCI card in, the machine refused to boot and
gives me the message:

   *****
   ***** Disabled the PCI USB card in slot 3.
   *****
   * *   An unsupported PCI I/O configuration has been detected. * *
   * *   Contact your HP service representative for warranty     * *
   * *   service to enable the card(s) listed above.             * *

I had no trouble with putting a card in my B132L, but it seems to be
more forgiving of hardware.  It has a 5v PCI bus where the C160 is 3.3v.

I've tried two different Ethernet cards and also a USB card I had lying
around - every card I have that was keyed for 3.3v.

I've updated to the latest firmware with no change.

I know this is a little off topic for the list, but it's my guess that
not very many other people except Linux users are putting weird hardware
in their PARISC workstations.

Anyways, if anyone knows of ethernet cards that will work on a C160 - if
you have similar hardware and a success story - I would appreciate
hearing about it.

	Kurt.

Errm, I can't say for sure, but IIRC there was a time when HP thought
it is useful to just allow HP certified/supported PCI cards to run in
their workstations.
Perhaps someone else can elaborate on that topic?

Well, many cards are universal, ie. keyed for both 3.3v and 5v.

I can't speak about C160, but in my C240 I was able to use a
DEC tulip and also a Intel EtherExpress PRO 100.
I didn't have so much luck with a noname ne2k and some 3com Vortex,
but it was about 3-4 years ago since I last tried ...
Anyway I think a DEC Tulip card should be your best bet.

I think HP did this due to bugs in the Dino PCI bridge. Certain revisions
have bugs that will quite likely corrupt data on cards that HP haven't
certified as working correctly (i.e. HP cards are known not to exercise
the bugs). Don't remember off the top of my head exactly which revisions
are affected, but if your B132L is actually a B132L+ it could well have
a newer, fixed, Dino rev. compared to the C160.

Yup.

Well.  The old rev. Dino does corrupt data (Actually, the HP errata
note is funny.  It states that Dino will cause corruption but *only*
when you do I/O through it.  Good thing I/O is not something you do on
a regular basis 8).

Anyway.  For a graphics card it's not a big deal whether a pixel on
the display gets corrupted.  And consequently - as far as I remember -
the firmware will reject anything but Visualize cards.

The solution is to find a new I/O daughterboard on ebay.  There's
probably a higher success rate in terms of getting a newer rev. Dino
if you get a board from a scrapped C180/C200/C240.  Join the exclusive
circle of Frankenbox owners!

BTW, are you really sure you don't have any PCI (UHCI/OHCI/EHCI) USB
card installed somewhere? It would be rather strange if it falsly
identifies your ethernet card as a USB card ...
