I don't know, the relevant line from your boot messages is

7. Outfield FW SCSI (10) at 0xf0830000, versions 0x9, 0x0, 0x7c, 0x0, 0x0

anyone like to comment on what that device is?

You probably ought to include CONFIG_SCSI_LASI, CONFIG_SCSI_ZALON, and
CONFIG_SCSI_SYM53C8XX, and see if it makes a diference, but I'm not
expecting it to.

The relevant document is still missing from the linuxcare website,
despite a bug filed against it for over a month now.  Fortunately,
I kept a copy of the old website active, so you can view it at
http://puffin.external.hp.com/parisc/hp9000_models.html

The relevant quote is:

 The PCXS and PCXT models include the NCR 53C700 device at various
SCSI-Clock rates for the built-in Single-Ended (SE) SCSI controller.
These older models use the NCR 53C720 (40 MHz) SCSI controller (where
supported) with the Outfield (O) chip for the built-in SCSI controller
for the Fast-Wide-Differential (FWD) SCSI bus.  The PCXS and PCXT models
do not provide support for an internal PC Floppy drive.

So it seems like we need to find you an Outfield device & docs :-)

Ah, I remember that page from long ago; thanks.

Oh, more h/w to annoy the wife with ;)

So CONFIG_SCSI_ZALON with some tweaks to talk to 53c720 on Outfield
rather than Zalon is needed.

Can you try this patch, compile CONFIG_SCSI_ZALON in, and let me know
what happens?

Re: FW: [parisc-linux] How do I use the FW scsi on 735?

[Matthew van de Werken]

Hi Richard:

I added the patch (I assume I added it correctly - the resulting vmlinux was
different), and ran the new kernel, with no change. The FW scsi is still not
recognised.

I tried the following combinations of drivers, with the same result:

(All of the following were with HP-LASI on and HP-ZALON on):

* No other SCSI drivers;
* NCR53c7,8xx support as well;
* sym53c8xx support as well.

None of these combinations works; any other ideas from anyone on how to get
FW scsi support? I am using the snapshot taken I believe on 9 April, with
the cross-compiler from that date.

If anyone has FW scsi support going (at the same time as the narrow scsi),
if they could mail me their .config file to compile the kernel I'd
appreciate it.

I am of course assuming that the FW scsi isn't working, by the fact that the
FW disks aren't being recognised at boot time, and the fact that I can't
fdisk /dev/sdx, for x != a.

Cheers,
MvdW

Shame :(  The Zalon driver is the one you are interested in.  My B180
with a Bluefish (Zalon based) FWD card runs the sim700, zalon, and
sym53c8xx drivers all at the same time, no problem.

It's possible I got the parameters wrong in my patch; the aim is to
cause drivers/scsi/zalon7xx.c:zalon_scsi_callback() to get called
for your interface.  It could be that is getting called but failing
for some reason.  If it is called, you should at least be getting
a line

        ......: Zalon vers field is ......

output on boot.

If you don't see that, perhaps you can investigate by adding a few
printk()'s to see what I got wrong.

zalon7xx_detect() is surely getting called, and that uses register_driver()
in arch/parisc/kernel/drivers.c to try and match your cards parameters
against one of the entries in zalon_scsi_drivers[].  Try and figure out
why that match is not succeeding for your scsi interface.

[Matthew van de Werken]

Hi Richard:

I'm a little bit of a beginner at all this kernel hacking business (well, a
rank beginner would be more accurate)...

What I'll do is turn on the verbose SCSI error reporting, and the SCSI
logging facility and try again.

I''l have to do a 'man printk' to have a look at what that function's syntax
is, then take it from there.

Cheers,
MvdW [who, despite lack of total success is having a lot of fun...]
