[parisc-linux] _working_ rbootd for redhat

[parisc-linux] _working_ rbootd for redhat

[penfold]

Hi all,

First up, thanks all - I love your work.

after much trawling of the list archive and altavista I was able to get rbootd
to at least boot the kernel on a 720.
CPU(s): 1 x PA7000 (PCX-S) at 50.000000 MHz

Given that finding this was not easy, how can we the patched source .tar.gz
available more easily on parisc-linux.org or puffin.external.hp.com ?

I _really_ hope its not somewhere obvious and I am just a nuff-nuff.

Also, Is there anyway to hard boot this machine form the serial port when
a HPMC has happened?
(eg, control sequence).

thanks,
Damian

*shrug*.  anyone want to do something with the parisc-linux booting
howto that's at oswg.org?

i doubt it.

Hello !

I also have a 720 (9000/720, with 50Mhz) and I often thought
about the idea of using rbootd.

Can you give me some hints, what you have done (what steps)
(I also have RedHat !).

What to do on the 720 machine (with `path lan0.....' I think),
wnat to do on the host, and how to prepare the linux boot image 
(lifimage) ?

By the way, have you booted linux now ?
I had the problem with the trap 18 (perhaps you saw it)
on the 720. It could be fixed by adding the `case 18:'
to that case (15,26, etc), and suddenly the 720 was working !!

With friendly regards

hmmm, not sure what you mean here.

In my case I disconnected all SCSI devices to _ensure_ the box would not
boot from disk.

All I do is let it search (or, _re_search if I had forgotten to start rbootd)
and then select path P0 to boot from.

Does your kernel see the scsi interface on the 720 ?

If so, I am keen to try your kernel - are you able to make it available
for download somewhere?
If convenient for you, you also email it to me.

Hello !

For the SCSI I have nothing fixed !
It works out of the box.

I have not sent any patch. I only tried it and it works.
So to all PA-RISC hackers, add the TRAP 18 there in the main stream !!

Ok, wonderful that your machine is also booting that way...

With friendly regards

Yes, and no.  we need a proper trap 18 handler that checks to see whether
it's a page fault or a misaligned data reference, and calls the right
handler.  This should not be too hard to write, but i don't have time
right now.

Is it not possible to add the entry in the meantime
with the well-known big triple X
	/* XXX hack.... */
for those people doing the first hackings on such old machines ?
Of course, some of these points will be forgotten....

I have not enough skills at the moment. I don't know the PA-RISC
arch here good enough, and I also have to deal with the low level
kernel code around the PA RISC here. 

Cheers
