[parisc-linux] Re: C110 question

Bryan,
In general, questions like this will get better answers from
the parisc-linux mailing list - see http://lists.parisc-linux.org/.

I'll take a first whack at it though.

The ISO image you downloaded has palo in it. Running palo with the
ISO image is either going to fail (best case, do no harm) or trash
the ISO image (worst case). I would guess the latter.
Make sure the md5sum output for the ISO image matches what's posted
on the website you got the ISO from.

When booting, answer Y to "interact with IPL" question with yes.
You have "manually" boot from the PDC prompt (aka BOOT_ADMIN prompt)
in order to get that question.

Then you can verify "console=ttyS0" parameter is set.
Disconnecting the keyboard should force the console output
to the serial port.

Oh - and several workstations may have issues with serial port numbering.
Ie what's labeled port A on the back may be seen as ttyS1 by parisc-linux.
Some of that has been fixed with newer kernels.
You would need to build a newer kernel and boot it via bootp.
This isn't as simple as it sounds...perhaps wait until a new
ISO is published.

In general the SCSI driver for Zalon works. The problem is with
IO MMU support for devices below anything other than the first IO MMU.

I dunno. I've only looked at the mach sources once for 712 stuff.

It's not secret - search for "console=" in the mail archives.

no. 256MB isn't that much at all. I'm running 2GB in my c3k
and once had as much as 4GB in the c3k.

XF86 is mostly working for B180 and 712's from reports on p-l mailing list.
If you have Vis-EG (normal built-in) graphics, it might work for
C110 as well since it's not using IO MMU (afaik).
