Re: Precompiled 2.1.131 binaries.

Linux on Indy problems.

Cross-posting this one to sgi.engr.linux. Maybe someone here has had succes with Linux on an
R4400 Indy.

Here are some answers:

Probably... could you see what it reports for the SCSI probe?

Yes, I get similar output describing vendor, model and disk sizes. All
are correct. If I get this output
am I OK in this regard. Should I compare this output with mine to look
for discrepencies?

Could you see what it reports for partitioning?

Mine says:

Partition check:
 sda: sda1 sda2 sda3 sda4
 sdb: sdb1 sdb2 sdb3

Yes, I get this feedback.

It says this because it can't find /sbin/init, because it can't find the
root filesystem.

That's what I was afraid of. At least my errors seem to be pointed at filesystem
mounting.

Two reasons: there's no fielsystem that has /dev/console for you, and I
never built in serial console support.  I will, thuogh.

It seems like I had it in the previous vmlinux kernel. I was using my irix-indy's
console port to
connect to the console port of my linux-indy. I never got feedback
on the local linux-indy's gfx
(prom> setenv console d). With this new kernel, the reverse is true
(now behaves like prom>
setenv console g).

Yes it is.

Aside from the config that I performed on the disk from IRIX (below), what else should I look at?

What I did (from my recollection):
irix% mk2efs /dev/dsk/dks0d1s0
irix% installer /dev/dsk/dks0d1s0
   cjwsh> MAKEDEV (What should `ls dev` look like at this point?)
   cjwsh> cpio.....
   cjwsh> exit
irix% e2fsck -fy /dev/linux-disk
cp /dist/linux/mipseb/vmlinux /mnt/vmlinux    (/mnt + /dks0d3s1)

prom> boot vmlinux root=/dev/sdb3 (similar)

Notes:
IRIX 6.5 is installed on an XFS partition dks0d3s0. Linux was cpio'ed onto an ext2 partition
at dks0d1s0. I have an IRIX made efs partition at dks0d1s1.

In this case, I am following the instruction included with "Linux-installer". In these instructions
there is no talk of using bootp/tftp/nfs for anything. Should these instructions work? Are these
better/same/worse than the instructions available on the webpage which call for using bootp to
get the kernel?

BTW I did try the webpage instructions as well. I get errors like cannot open system console.
This happens after the disk discovery completes OK or at least similar to your example.

Is the reason for needing IRIX on the linux-indy?: a) Needs to boot sash from VH? b) Be able
to run installion script which executes under IRIX? c) Some other reason?

Thanks,
Chad
