Partial Success Report

Partial Success Report

[Jeff Coffin]

Hi All, 

I've been reading this list for the past many months as I slowly and
infrequently try to bring a dead Indy R5000 back to life, then get
Linux up on it.  The box had a dead disk and still has a bad graphics
board, but I've managed to get IRIX installed and operational on one
disk, another one installed and fx'd from IRIX; all from the serial
console (minicom) and remote X on my x86 Linux (RedHat 5.1) box.

I think there's something very wrong with the gfx card 'cause when I
try to start X under IRIX it complains about a failed context switch
and loops with the same error message for a few iterations, then
hangs. (Sorry I don't have the message with me, it's at home.  I can
post tonight it if it's relevant)

Last night I got the HardHat kernel to boot via the bootp method
described in the Howto and, as expected from the experiences of
Richard Hartensveld, it hung looking for a console.  I then grabbed
newer kernels (2.1.116 and 2.1.121) from the /pub/test on the ftp
server and attmepted to get them loaded by the same mechanism, but
both of them hang after loading via tftp.

I don't know where to go from here, so I'm looking for ideas.  Hinv
and the boot log from the hardhat kernel boot are below.

I'm thinking about removing the gfx board entirely and seeing if that
has any effect, will that do me any good?

Any help or suggestions would be appreciated.

It *should* find an initial console if you have mounted the root filesystem from
the hardhat CD correctly. 

You can probably install hardhat on a i386 box in your local network if you
want, and boot directly into an already installed hardhat via nfs-root. That
hardhat default installer is _very_ annoying, it crashes all the time.. (signal
11, out of memory etc..), I don't know if this would solve your problems - but
it helped me... :)
Give the --root <rootdir> option to rpm, and install the needed rpms from the cd

It would probably not make much difference, "Warning: unable to open an initial
console" isn't caused by a gfx board neither an old kernel, but from an
incorrect /dev/console.

I'm currently running hardhat diskless, I'm only using the IRIX harddrive when
I boot (the bootp command is loaded from the harddrive).

Maybe that's the problem, it all *looks* right.  Is this the case for
the harthat kernel as well as the 2.1.116 and 2.1.121 versions off the
FTP server?

Let's see if I have this straight:

from the PROM, it I do

boot bootp():/vmlinux

and NFS is configured properly (more or less as per the HowTo) on the
i386 box, the kernel will boot and find the NFS root filesystem as
configured in exports or do I need to pass the kernel the nfsroot
param to get it to properly mount the install root?

That's what I thought.  I was speculating that the hardware trouble
was causing the kerel hangs.

Not from the PROM?  How does that work?  (I'm new to SGI's and getting
IRIX up at all from just a CD and a new hard drive was a "learning
experience") 

I'll play with it some more tonight or tomorrow when i have the time.

Thanks for the suggestions.

Are we sure that the XZ chipset you have is supported? Get a newport one :)

I thought the bootp command was loaded from the IRIX partition, because it
didn't work when I removed the IRIX harddrive, atleast it didn't with my old
PROM.  It claimed that it couldn't find the bootp() command - maybe I'm out of
my mind, I'll check next time I remove the cover...

bootp() is just a ARC filename which is either interpreted by the PROM
command interpreter or by sash where sash afaik is nothing other than the
PROMs compiled with special flags.

Could you please lookup major and minor number of /dev/console on
your root filesystem ? It should be major 5 and minor 2 to work
properly with the serial console.

please try to boot these kernels with bootp()/vmlinux console=ttyS0 (also
try ttyS1) and a terminal hooked up to one of the serial ports (in .116
ttyS0 is port 2 and ttyS1 is port 1; I've changed that in .121, but I'm not
sure if this fix is already in the precompiled kernel). It's possible, 
that I've messed up the card detection so, that it panics, when there is 
no newport installed.

Thomas.

The command 'boot bootp():' requires a harddrive, but I can run 'bootp():'
diskless. Does the 'boot' part of the command tell the PROM to use sash?

       That is, bootp() is part of a path.  There is no bootp command.

       sash, unlike most PROMs, has one or more (read-only) disk file
systems bound into it.  On Indy, older sash versions can read efs volumes,
and newer ones can also read xfs volumes.

      Try

	boot -f bootp():

This avoids trying to load sash.

Nope, didn't work.  The 116 kernel makes the power light blink red to
green ad infinitum and the 121 version appears to load, but the
console is elsewhere.  I'm using port 1 for the serial connection
(it's setup thusly in the PROM)

The default kernel still boots OK and appears to mount the nfsroot:

but then nothing....                                                     

BTW, I'm doing the whole thing from a serial console (minicom).  The
gfx card doesn't work from IRIX either.  One of these days I'll
replace it, but it's not real high on my list of things to buy for
$200+.

no, but I've got major and minor wrong. It's major 5 and minor 1.
