[Olaf Zaplinski]

Hi all,

can someone please point me to a Howto/FAQ? I'd like to put Linux on my SNI
RM200 machine (R4600, 64MB). Can I use the Hardhat distribution, or does it
run on SGIs only?

The RM200 was supported only in little endian mode with the Windows NT
firmware - Nobody knows (chance is little) if the tree will still work.

You will need the decstation root not the hardhat tarball as that
is strictly big endian.

Where do I find it? I saw the debian-mipsel dist on ftp.rfc822.org, but as
there is no doc at all, this dist is unusuable... perhaps I am lucky with
that, I strongly dislike the Debian dist.

Try searching for 'declinux'.

Btw, what kind of doc do you expect? The MIPS port is, well, everything
but a "customer linux" right now. It's more-or-less working for
people who know what they do. There's no installer comparable to
a regular PC installation (insert boot CDROM, press enter sometimes,
ready). Everything you can expect is a tarball, which can be
mounted via nfsroot. There you can find a kernel inside which you
can boot over bootp/tftp (or via mop, if you have not so much luck).
Then, you can locally fdisk/mkfs/mount your HDDs and copy everything
by hand. That's the installation.

Anything else still needs to be written. I've started an approach
of a clean debian root filesystem (ftp.lug-owl.de) you may want
to try. However, Debian is currently the only distribution supporting
those machines at all. The declinux image is heavily outdated and
ships a totally broken libc with it... It's no fun!

Hm I am still working on the boot floppies for debian, when I have the time.
for mipsel they should work, but I only build them for mips.
the problem on mips was the sgi disklabel, but that isnt used on dec.

Question in charge: Do DECstations really have floppies? Mine do
not... So vor me it's only relevant to have an nfsroot.tgz allowing
me to install further packages...

Well - the Maxine (Personal DECstation) has a floppy controller and it was
possible to order it with a floppy disk drive installed, but I have not
seen one of these in real life yet :-).

Besides Maxines DECstations don't have floppies. Well, there are some with SCSI
floppies but that doesn't count.

Anyway, everything that fit's on a floppy would fit into a ramdisk as well.
Compile this ramdisk image into the kernel, boot with "root=/dev/ram", et
voila...

Working on "boot floppies" *does* make sense, IMHO.

Well, a few Indys were shipped with 3.5" SCSI floptical drives which afaik
have 20mb capacity.

Indeed, I even own such a nifty thing. It's pretty cool, with one problem:
No media ;-) . But it's able to read floppies, I'm altough not sure
if it will boot.

In theory it can.  In practice every machine I've ever is violating the
ARC standard massively, so only trying will show.  For Indys probably the
prefer installation media will stay NFS or CDROM for all times.  Now if the
darn thing would just handle ISO9660 CDROMs ...

I've used an SGI personal-Iris 4D/35 which had a real floppy drive.  Of
course, I guess it's questionable whether the docs will ever surface to
port Linux to it.  It had a 36Mhz R3000 processor in it if I recall.

The package is only called "boot-floppies" - It doesnt have much in common
with "floppy" images on architectures not having floppy drives. It more
or less the debian installer source package. They for example
build kernel/ramdisk images with the installer for architectures
capable of bootp/tftp like Sun SPARC. We will do similar for
Decstations and SGI and forget the "real" disk images. The problem is
that most of the software is more or less custom debian and will require
some work concerning SGI Disklabel, Kernel 2.4 etc - Henning has done
a lot in there and hopefully Decstations are much simpler (DOS Disklabel)

But still - The biggest problems are glibc, gcc + binutils.

Re: FAQ/

[Olaf Zaplinski]

Huh, I don't expect comfort. But I expect a x68 Linux users guide to the
world of MIPS systems. Okay, I know my RM 200 quite well, had compiled
several progs under Sinix, put it in LE mode and installes WinNT 4.0. I use
Linux since the 0.something kernel. The problem is that the Debian WWW site
consists of lots of "404" errors. On the ftp site there is no docu at all
that would tell me how to proceed. For Hardhat, I have found this
information.

What I want: a documentation of the form:

- how to prepare your bootp server
- how to boot the kernel via bootp
- how to start some install script *or* boot your mini-dist/root-fs via NFS,
fdisk, cp and enjoy

That would be enough.

Install bootp (or dhcpd, which can do bootp as well) and read its
documentation.

This is specific to your machine's firmware.

less  ./linux/Documentation/nfsroot.txt

~~VeryShortVersion~~:
- Activate "IP Auto Configuration" in "Networking Options"
- Build NFS directly into your kernel; there, also activate NFS-Root
  support
- "root=/dev/nfs" as one command option when booting the kernel (this
  is the easyest method). Then, the client mounts /tftpboot/<IP-Addr>
  from the server which did the bootp reply. Otoh, you could
  configure your bootp server to provide a different boot server
  or boot path.

fdisk and cp (btw, you should better use tar in a pipe for that...)
should be no problem...

I have a much newer one ready, but I don't have upload permission
anymore on oss.sgi.com. I've asked Quentin and Ralf to arrange this,
but nothing yet... As soon as I can put files on oss again,
I'll upload my new RH6.1 based root image.

hi,


sorry for the missunderstanding. I meant the debian-bootfloppies and
only the initrd which can be transfer with the kernel over tftp. I know
sgi's only have flopticals. wiht the so called bootfloppies you will
be able to install debian as on the other arch's.
