Re: [parisc-linux] C180 netbooting

[Richard Hirst <rhirst@linuxcare.com>]

I don't recall any reports that C180 works, so it might just not be
supported.  

I can tell from your log that the scsi chip is basically working, it
has executed a few script instructions, but in each case it has hung
on a SELECT instruction.  If there is no device on a given ID the
chip should interrupt and say so; in this case there is no interrupt,
so the higher level code times out and resets.  From the log it appears
that the chip hasn't tried to generate an interrupt, so it is not just
an interrupt routing problem.

Do you have terminators on your scsi bus?

What devices are present, on which scsi IDs?

If you let it run on beyond this point does it continue to generate
errors for scsi IDs up to ID 6?

I guess the C180 has more than one scsi bus, these errors relate to the
narrow scsi bus, probably used for the CDROM.  If your disks are on
another scsi bus, and you can install va the network, you could perhaps
get going that way.

Feel free to send me a complete log of the boot msgs.
