I signed my `thou shalt not do nasty things with this box' papers for
the Indy last night, and I have it from a highly reliable source that
it'll be delivered or available for pickup today.

I'm leaving in an hour for San Fran and then Mountain View, but I've
got a friend here setting it up for me with a serial console on my
machine.  I _should_ be able to get it booting with that, once I
figure out what the filesystem bits have to look like.

Many thanks to everyone for the opportunity to work on this, and
especially to Kevin Needham for his tireless efforts to help me get my
hands on this machine.  This is going to be awesome...

Mike

Good!

I talked with the SGI people in Mexico, still no news regarding the
Indy arrival.

I am going to LinuxExpo to talk about the new Linux RAID-1, 4 and 5
(www.linuxexpo.org).  I am leaving tomorrow morning.  I will be back
on sunday evening, I bet my Indy will be here at my return :-)

Cheers,
Miguel.

Assuming you're using a Linux box as TFTP Server here are old versions of

------------------------------------------------------------------------------

/tftpboot/193.98.169.17/ is Mipsy's NFS root, 004095e11dc2 it's 48 bit
Ethernet hardware address.  Note that the kernel makes some assumptions
about where the NFS root is on the server (/tftpboot/<ip>); if you
change that you need to pass some kernel options.  My setup is such
that I don't need to pass any options at all.

Does that help?

This German Computer magazine claims to have seen a prototype
of Linux on N64. I send a msg to confirm the prototype.

Actually (I guess I should have made this clearer...a couple of people
have sent tftp help) I meant tips on what should go in the NFS root
area.  Can I just pull stuff down from davem's private archive and
untar, or have things changed since then?

I assume it's got Irix running at the moment.  If so, try 'hinv'.

Ariel....maybe you should put the tar's on netengr.engr:~/dm/alambie on
ftp://reality.sgi.com/private/dm/ till I get linux.sgi.com sorted out.  There
should be everything you need to get multiuser in there.

So damned close we can taste it.
I can tftp the kernel off neon, the bootp server is up (but not tested
-- anyone have a good way to test without a reboot), and we've got a
serial terminal set up.

We've still got to get the console working on the serial line, but we
should be OK with that.

What's got me confused is this, from the archive (I think it's wje's
message):

     On an Indy, the booted kernel (or other program) must be in MIPS
ECOFF format.  On Moosehead, the kernel must be in ELF format.  The
"-coff" option to the IRIX ld will cause it to create an ECOFF binary
instead of an ELF binary in the final link, even if all the input
binaries are in ELF format.  If you want to boot an ELF kernel on
Indy, you have to boot an indirect loader.  You can use the IRIX sash.
Put sash in the volume header on the Indy, or in a bootp-able place on
the host system.

-----

1) Where's sash?  A find / on my Indy didn't turn up anything by that
name.
2) What exactly does `bootp-able' mean?  If I stick it in
/tftpboot/205.207.220.72/sash, does that count?  (The Indy is my only
IRIX box, and I don't have the installation CDs, so I'm somewhat
loathe to go screwing with the disk.)
3) Once I get it booting (pls, pls) will the Linux kernel know how to
talk to the serial console?
4) I've just got the kernel as /tftpboot/205.207.220.72/vmlinux.  DO I
need to add .IP22 or anything?

Any ideas?

Just in case the real experts on this don't answer.
I'll give my 0.02 ...

Check out the following man pages:

dvhtool (1M)            - modify and obtain disk volume header information
vh (7M)                 - disk volume header

sash is hidden in that volume header. In a normal IRIX system,
The ARC PROM boots sash and sash boots /unix.

/unix is ELF (32 or 64 depending on the platform) in every IRIX
since 6.2 (I think). Used to be ECOFF earlier.

sash is ECOFF on Indys and ELF in newer systems as Bill Earl
said. One of the things we need to give you are the sources
for sash, right ?

I'll see what I can do on the sash thing. (Actually was on my
TODO list for a while.)

     Usually, it is only installed on the volume header, but you can
extract it into a regular file using dvhtool.  Sometimes you can find
it in /stand.  To extract sash:

<tanoak#1> dvhtool /dev/rvh

Command? (read, vd, pt, dp, write, bootfile, or quit): read
Volume? (/dev/rvh) 

Command? (read, vd, pt, dp, write, bootfile, or quit): vd
(d FILE, a UNIX_FILE FILE, c UNIX_FILE FILE, g FILE UNIX_FILE or l)?

    See the tftpd man page.  The default directory for IRIX tftpd is
/var/boot/, so /var/boot/sash and /var/boot/vmlinux would do for boot files.

    If you don't have the installation CD's, I recommend that you back
up the disk, perhaps to a second disk (complete with volume header and
root partitions), so you can recover from any potential failure.  The
"cp" command in the prom can be used to copy disk to disk to recover.

      I believe that David Miller had that working.  How do you tell linux
to use a serial port as the console (in single-user mode)?  For IRIX,
one does

	setenv -p console d

(for "debug" console, as opposed to the usual "g" for "graphics" console).

 > 4) I've just got the kernel as /tftpboot/205.207.220.72/vmlinux.  DO I

      If you put sash and vmlinux in /var/boot, then do

	boot -f bootp()bootphost:sash

from the PROM, where bootphost is the hostname of your IRIX system, and then

	boot -f bootp()bootphost:vmlinux

from sash, all should be well.  Note that you can boot an ELF kernel directly
from the PROM on an Indy with a newer PROM image (such as the PROM for an 
Indy R5000 system), so try that first.  If it works, your Indy has the newer
PROM, and you can forget about sash.

     By the way, it is pretty easy to write a little program to convert
a kernel ELF binary to an ECOFF binary, discarding most of the symbols and
other stuff, assuming you have the header files for the file formats.
(The result would not be acceptable to many of the tools, such as dbx,
but it would be bootable.)

     For a production linux for the Indy, the most reasonable approach,
however, would be to make silo or whatever boot program you are using be
ECOFF, so that old PROMs are supported.

OK, that's what I thought.  I just wanted to make sure I was on the
right track when I read `bootp-able' as `tftpable in the right dir'.

That I will do.
Will that work with differently-sized drives?

Ugh.
On Intel, you have to use a patch.
On the SPARC, you just have to set things up right in /dev.
I shall hope that it's SPARC-ish on the Indy and poke around for good
instructions on that.  (I shall also hedge my bets and copy DaveM on
this message. =) )

I've got an R5K, so that'll make things easier.

I think that's the plan.

I'm having some trouble with the serial console, though.
I did an `nvram console d' and that took, but I fear that I've got to
set something else, since my serial cable is connected to port 2.  The
getty I'm running on ttyd2 works fine, FWIW.

When I reboot, I get nothing on the serial console until the getty
login: prompt.

(I can't think off the top of my head as to why I'm using that port,
but I think it had something to do with the available cabling.  I'm
not physically with the machine until 1400 EST tomorrow, but Josh
should feel free to step forward and explain it. =) )

     Yes, but the drive to which you copy the data will have to be bigger,
but it will then not appear to be any larger than the original drive.
That is, the partition table in the volume header will claim that the
second drive is really the same size as the original drive.  This is of
course ok if you only want the extra drive as a backup.

      Yes, you really need two serial lines, one for the console (port 1,
ttyd1) and one for the debug port (port 2, ttyd2).  At least, that is the
way I control my test system from my host system.  Here, we usually use
an Annex Ethernet-based serial concentrator for serial ports, and connect
via telnet (or the Annex rtelnetd) to the serial ports, which are then
wired to the test machines.

       The PROM talks only to port 1, so you are seeing what I would
expect.

     This appears to be a bug.  The R5000 does have the wait instruction.

Actually, you can do it with
boot -f bootp()server:/vmlinux nfsaddrs=my.ip.ad.dr:nfs.ip.ad.dr

It mounts it now (I have the NFS daemon running with debugging on so
that I can watch) but it just stops after it looks at tty[4123 -- in
that order].

I'm going to see how the SPARC guys did it; I think it's just a matter
of getting the device entries correct.

Yeah, and that's what I'm using for my root filesystem.
It mounts everything and checks out stuff like /var/log/utmp (!), but
then hangs after it looks at the ttys.

Curious...

     Can you pass the information to the kernel via the command line arguments
or the environment variables?  (argc, argv, and environ are passed in $a0, $a1,
and $a2 by the PROM or sash to the kernel on entry, just as they are passed
to a main program in a regular process; you can look for the "netaddr" environment
variable to find your IP address:

	netaddr=192.111.24.24

Set netaddr at the prom this way:

	setenv -p netaddr 192.111.24.24

     On an Indy, the R5000 and R4600 are basically equivalent, except
for the MIPS IV extensions and larger caches (32 KB versus 16 KB) on the R5000.
The R5000 does have built-in secondary cache control, which is used on the O2,
but it is not used on the Indy.  On the Indy, the R5000 uses the same off-chip
secondary cache controller as the R4600.  The wait instruction operates the
same on both processors.  The wait instruction is not really essential in any
case, since its main purpose is to save power, and the R5000 and R4600 don't
use much power anyway.

Wierd stuff here.
We've got it mountinng the NFS partition and running /bin/sh, but we
can't type anything to it at that point.
It's kinda weird, because we see the `#' prompt, but stuff I type to
it isn't registering.

stdin in /dev/cua1, FWIW.

I'm going to try to get some better diags, I guess.

The machine we're working on, bogomips, is in Ottawa, Canada.  Mike's on
business in Mountainview, California.  Joshua "boot boy" Lamorie handles
the hardboots, and I offer petty advice from Boston, watching Mike use
minicom in a ytalk session through a serial connection.  Odd, but it
works.

Does anyone know the the status of gcc for sgi-linux?  I understand the
cross compiler between Irix and sgi-linux is operational.  How about a
native compiler?  I'm keen on porting a ton of RPM's...

Linux doesn't really check; instead it has encoded which CPU types
have a wait instruction.  I add the R500 to that list.

 this brings up the question: do we already have drivers for
the textport? Not to speak of an X-Server? How are we (SGI)
going to handle this? As far as I know we never published
the hardware dependent parts on the X11 distribution, did we?

Some better information about my situation, now that I'm not as
rushed:

- I have a serial console on port 1 of the Indy, and I'm talking to it
via minicom on my Linux box.  WOrks great.  Sometimes BRK gets me back
to the PROM, sometimes it just hangs, but I can live with that.
- The boot process goes pretty well, but when I get past the root
mount (using init=/bin/sh), I can't interact with anything.
- I see the `# ' prompt, I get stderr output (!) but the following
commands (which do execute) produce no output:
echo "ttyS0" > /dev/ttyS0
echo "ttyS1" > /dev/ttyS1
echo "cua1" > /dev/cua1
echo "cua0" > /dev/cua0
- If I try to access /dev/console or /dev/tty[1234], I get "can't
create /dev/whatever: Error 19", which seems to be "no such device".

If someone with the appropriate tools could build me a static tail
binary, it'll make the experimentation go a fair bit faster.

I'll be back in Ottawa tomorrow afternoon for a few days, so I'll be
able to work on the console, but since I'll be travelling a _lot_ over
the next few weeks, having the serial stuff work properly is still
important.

I'm still using the dm@neteng 2.0.12 kernel.  Ralf, do you have
anything else built over there you want me to test?

(If it'll help, I can set Miguel and Ralf up with appropriate access
on neon so they can experiment.  It'll take a few days, but if it
keeps those precious geek-cycle from going to waste...)

I also have to deal with ARC machines (the little endian NT stuff).  By
definiton they have to support ECOFF; everything else is optional.  This
brings in the extra issue that the loader needs to be relocatable.
MIPS-ECOFF configurations of GCC can't do that and the linker dies when
loading ELF PIC code into an ECOFF executable.  Unfortunately fixing is
nontrivial.

The {Net,Open}BSD people already have a converter tool which they use to
generate their kernel executable.  It would solve the ld problems.
I did some work on it and I should probably finish it ...

I don't think David ever worked on an R5000.  The only platforms were R4600 &
R4400...soooo, there may be some issues to be resolved.

I used to have that...you probably haven't got a rarp server set up, so it
can't find its address.  One of the things David was going to add was that
ability to read it out of NVRAM...but that wasn't high on the priority list!
 For now, the only way is to have a rarp server.  The other way is to have the
root file system on hard disk....but to do that you need to boot linux and copy
it across.
Kind of the chicken and the egg situation!

Did you get my root filesystem etc off http://reality.sgi.com/ariel/alambie.
This should give you the bits you need to get multiuser (init), set up
networking and mount disks.

Have you set up the 'init' environment, or are you just using the plain 'root'
package.  If the later, I seem to remeber that the kernel looks for init, but
doesn't look in the correct place for the shell.  There is a boot argument that
I used to use to get the shell...can't remeber what now, but it was real easy
to find in the kernel source....

Even if you are using init, you might want to just boot the shell first to
track down what is happening!

Actually in this case Ralf's code for wait instruction detection
happened to work out of the box on my R4XX0 test machines back at SGI,
so it apparently does need to be looked into for the R5k.

Try 'init=/bin/sh </dev/cua1 >/dev/cua1'.  I seem to remember you need that.
Sorry all this seems to be coming piece meal, but it's been a long time since I

reminded!

BTW, if you use the init package it will take care of all this stuff...you
should be able to just lay it over the top of the root package on your nfs
disk.

You will need to edit inittab for the serial devices...it's set up for the vc's
on a 'headed' Indy.

    With management authorization, I provided the technical details
for the graphics hardware (and all the other Indy hardware) to David
Miller, who I believe got a textport driver working.

     As far as I know, all QED processors have the "wait" instruction.
All the 0x2???  processor ID values are QED processors.  Here are the current
values:

#define C0_IMP_NEVADA	0x28
#define C0_IMP_RM7000	0x27
#define C0_IMP_MAGIC	0x25
#define C0_IMP_SONIC	0x24
#define	C0_IMP_R5000 	0x23
#define	C0_IMP_R4650 	0x22 
#define	C0_IMP_R4700 	0x21
#define	C0_IMP_R4600 	0x20

I don't know which processors are SONIC, MAGIC, or NEVADA, but I think NEVADA
is the new RM5260 (a low-cost R5000).

This is one of the things that weren't done and we want to get done
by the Linux/SGI developers.  I believe that Miguel is one of the
best people to make this happen.  If we can just get his Indy R5000
out of the bureaucratic mess.  Miguel's Indy was shipped three weeks
ago to Mexico and requires a "special permit for used equipment" by
the Mexican customs to be provided by the SGI Mexico City office)

I hope Miguel will send us some good news soon.

We already have drivers for 'textport'....well actually it takes over the whole
screen with a font that allows something like 132x80 from what I remeber.  This
has VC support so you can do the usual Alt-F1 etc like on a PC based linux box.
 No work has been done on the X-Server yet.

How are we going to do this source tree thing?
I'm kinda green when it comes to CVS, but I can be taught simple
tricks.

I'd like to start mucking with things like the PROM netaddr
autodetection and such, but I don't want to make anyone's life more
difficult than necessary.

Looks like I may be getting a machine here to see if we can migrate
some of our non-Oracle machines to Linux/SPARC.

Anyone know if the emulation is up to hosting the Linux/Indy
cross-compiler?

In related news, we'll then have Linux running on 5 architectures in
the same room (Intel, Alpha, SPARC, ELKS, Indy).  Maybe I'll steal the
PowerMac too... =)

It should be straight forward, 32-bit to 32-bit crosses under gcc work
flawlessly right out of the box for everything I've ever tried.  It's
when you cross from 32-bit to 64-bit that you may hit a bug or two.

   In related news, we'll then have Linux running on 5 architectures
   in the same room (Intel, Alpha, SPARC, ELKS, Indy).  Maybe I'll

ELKS, that is cheating ;-)

I've got the necessary patches to make the binutils and GCC work as
Linux/Alpha -> Linux/MIPS crosscompiler.  Mike, if you need them remind
me to send them if you need them.

Why do you need the emulation for on Linux/SPARC?   You just need to
run configure on Linux/SPARC with the proper --target option and you
will get your native cross-compiler in a second.

You need to configure both binutils and gcc like this.

(I think you're confusing host and target.  If you want IRIX to generate
code for Linux the IRIX is the host and Linux the target os).

GCC does that as well as the binutils.  Truely pervert people can even
build GCC / binutils on a host of type a to run on type b and generate
code for type c.  I did that once or twice to build the first native
compiler for Linux/MIPS.

Try something like:

  ./configure --prefix=/usr --target=mips-linux

to configure binutils and GCC.

I was under the impression that building GCC for the Linux/SGI target
was non-trivial.  Ralf made mention of some patches, and since there
are binaries available for Solaris...

If GCC can support it with a --target choice, that'll be great.

:As promised, here is Miguel's answer.

:  Ralf
:

Miguel's answer is excellent. For the non-SGI'ers on the list
I just would like to add:

1) IRIX has many features that important customers require
   (e.g. trusted IRIX capabilities, real time scheduling
    and many more) that actually make it slower than Linux
   (in general). As a vendor SGI is committed to support
   these features from low end to high end for a long time
   to come. IRIX is big. Linux is smaller and faster.
   Once we have Linux running and we'll start running simple
   benchmarks you'll see this very clearly. Another big feature
   for our customers is XFS. Linux doesn't support a safe file
   system, IRIX does (try to turn off your Linux box and you
   lost a lot of stuff, unlike on IRIX with XFS.

2) IRIX needs to run on machines that are incredibly different:
   from uniprocessors through SMP (which Linux is now getting at)
   to the S2MP model (no shared bus: Origin family) every feature
   added to support S2MP (the Origin line) may potentially complicate
   and slow down the uP desktop case. SGI customers demand
   one source base. They want to compile on O2 and run on Origin.
   Linux is just starting to get a feel for how complex is SMP
   vs. uP so it'll naturally run great on a uP but wouldn't be
   able to take advantage of the most scalable architecture of
   the Origins. As we've learned this requires rewriting large
   parts of your kernel from scratch. Which is why SGI is doing
   Cellular IRIX
   http://www.sgi.com/Technology/Irix6.4/cellular_irix6.4tr.html

3) IRIX runs only on SGIs and to get upgrades you need to
   pay for support. Linux runs on many platforms. It is free
   The common source base gives it a great advantage for people
   who have mixed envs. It is affordable and ideal for hackers.
   it has a big and fast growing following.

4) IRIX has no chance of beating M$oft. Linux doesn't either
   but it has a bit more. Just kidding.

The guy who said "SGI has hundreds of highly paid engineers
tuning IRIX to run fast on MIPS" simply misses the issues.
They are much more complex than that.

Both Linux and IRIX have their place. Each of them is good
at different things. People should have a choice between SGI
taking care of all their needs and the alternative to have
full control of their software.

Linux on SGI should prosper.

Btw, Linux/MIPS errno values are (almost) the same as IRIX.

This is the fun part.  You probably need to cheat to make textutils'
autoconf work for crosscompilation.  It's usually ok to run configure on
a Linux/Intel system (Using a glibc system is a good idea) and then
crosscompile with a command like

  make CC=mips-linux-gcc CFLAGS="-O2 -pipe" LDFLAGS="-static -s"

Autoconf is *nice* in almost all cases but it's often a bitch when
crosscompiling, so feel free to use every dirty trick in the book ...

Thanks, would be useful.

I understand that the EFS and XFS file systems are proprietary to
SGI.  I don't really understand why SGI would care if the EFS file
system were divulged but I can understand the XFS file system.

What I wanted to suggest is that SGI provide a library (.a file) that
can be linked with Linux to provide EFS and XFS file support.  If
necessary, we could charge some nominal fee and require some kind of
non-disclosure or promise that the objects won't be reverse engineered
or something.

As a minimum, provide these drivers only to employees.  It would sure
make development easier if we could mount SGI file systems.  My
biggest reason for wanting them supported is to access SGI CD ROMs.

Anyway, just thought I'd add my $.02.

I thought that there was a program available for Linux that would read EFS
file systems, although I can't for the life of me remember the name.

I think the better question is when will we start distributing CDs in a
standard format...  Yeah, yeah, backward compatibility, I know ;->

   do we already have drivers for the textport?

I wrote the text console driver for 24-bit Newport INDY frame buffers,
and it is in the SGI/Linux code.  I was never able to get around to
doing the 8-bit frame buffer card driver though, so if you've got one
of those in the INDY you are a out of luck for now.  (hinv -v from the
firmware prompt will tell you if you have the 24-bit or 8-bit card)

     Does the textport driver run in color-index mode?  If so, it will
probably work on the 8-bit card.  The cards are largely identical, except
for the depth of the frame buffer.

  Could someone tell me how big the kernel is for the MIPS chip? I
need a rough estimate of the size of a minimal kernel with networking
support, probably no file systems nor disks. A project I'm working on
is currently using VxWorks. We're suppose to add a bunch of large, off
the shelf software components to it and I'm worried about running
everything in one unprotected address space. (All it takes is the web
browser to hickup and the box will crash. But hey, no one has ever
heard of a web browser crashing!) Does anyone have an estimate of the
process switching time? That's one of the things the hardware types
harp about for their multimedia apps.

Maybe I should have added:

That's less than half the size of IRIX (6.3 on my Indy)
and about a quarter of the size of IRIX64 (6.4 on info.engr)

Of course, IRIX has much more in it, like XFS, Trusted IRIX,
Real Time and priority-classes scheduling, MPP (in 6.4), digital
media device drivers ..., but I thought you may want to know the numbers.

IRIX64:	2992844 (text) + 967960 (data) + 405460 (bss) = 4366264  (6.4)
IRIX:   2224072 (text) + 202752 (data) + 196560 (bss) = 2623384  (6.3)

	Does the textport driver run in color-index mode?  If so, it
   will probably work on the 8-bit card.  The cards are largely
   identical, except for the depth of the frame buffer.

If memory serves, I left the chip in the exact mode the firmware has
set it to.  So if the firmware sets up the card to use color-index
mode, then I do as well in the driver.  (I think I did this so I did
not have to deal with monitor frequencies, and resolutions, and that
sort of thing)

But my text rendering code may make assumptions about frame buffer
depth, I draw them using the various simpler raster operation commands
the Newport has, so someone who knows would have to look at my code.

There was a bug in the linker/assembler/gcc that I don't recall if I
fixed for the kernel build tools.  What it would do is leave the
symbol information for all local compiler generated symbols in the
kernel image (the problem was gcc was generating local symbols using
one convention and the linker/assembler were expecting them to be in
another format, so they just got left in the symbol table).

This would cut down the size of the Linux kernel quite a bit.  I know
I fixed it in the userland gcc because this bug prevented some
important programs (lat_ctx ;-) from compiling due to ELF symbol table
overflows.

 Isn't there something calles "efslook"? I found it mentioned
somewhere in the SGI FAQs. Probably does not really "mount"
the EFS volumes, but you should be able to read them.

  Definitely. Do away with EFS as soon as manageable.

Assuming it's all cleared with everyone, and we get a source
repository somewhere to play with, I might give it a shot.  Does
anyone know if the efslook stuff is GPL'd?

Hey, I'd love to switch to iso9660.  Unfortunately, how do we read all
the CDs that have already been generated?  For example all the free
source code that has been generated on the Developer's Toolbox and
stuff.  Also, after a linux kernel has been booted, it would be nice
to mount SGI file systems.

At this point, since we are moving away from EFS, it is possible that we would 
be willing to donate a version of the EFS code to Linux.  I can probably get 
that cleared.  But someone else would have to do the port, I'm too busy.
If you find someone to do the port, let me know.

If you can get it cleared, I'll do the port.

Initially, I'll port it to my system at home and create an EFS
filesystem on a Zip drive and see if I can read it here in the office.

If that all works, then I'll pass my source to one of the other guys
who actually has a linux SGI box.

Adding 9660 does not require us to remove EFS.

I think the issue may have more to do with PROMs and sash and stuff like that
than the OS proper.

Hello,

    I was reading a very nice paper on the design of XFS and found a
mention to a volume manager.  According to the illustration, it seems
like the volume manager sits between the buffer cache and the disks,
which led me to believe that it is implemented as a device driver. 

   Where can I get more information on the design of IRIX's volume
manager?  Is there any nice paper like the XFS one published?

Cheers,
Miguel.

Hi all,

due to problems with the current bootloader Milo for the little endian
machines when recompiling I finally took myself the time to fix the
ELF to ECOFF converter.  This should also solve the problems with
older ECOFF-only firmware in Indyies.  The code will be in Milo 0.28
to be released as soon as it has been tested on Magnums/Olivetties.

I've been away for a few days, so sorry about the late reply :-)

It definitely works on an 8 bit machine.  That is what I have used in the past.

Hi all,

I've uploaded Linux/MIPS 2.1.36 to ftp.fnet.fr and kernel.panic.julia.de.
The file will appear at FNet later today when one of the admins has
moved it online.

The number of changes compared to my last real release 2.1.14 is too
large to be enumerated and people still having patches against this
release will probably have their fun with them ...

This release integrates all of Linus' kernel patches and most of the
MIPS specific patches I still had on hold.

Because I don't have a Indy for testing this release is completly
untested on SGI machines.

  Ralf

I'll take care of that when I get in to the office today (home sick
this morning).

Ok.  Please send patches and bug reports to ralf@uni-koblenz.de.  I'll
be off for one week in the Silicon Valley and my other folders will
probably be hopeless overflowed when I return.

I've installed Ralf's mips-linux-targetted gcc and binutils, and I'm
getting _real_ close.

It's getting to the linking stage, but it's looking for a file called
crti.o, which I can't find.  I've got crt[1n] from my Indy's /usr/lib,
but there's no crti.o to be found on there.

Is this a configuration problem?

Mike

Turns out that the crti.o stuff was on the Linux/Indy root, so I'm in
business now.  I just compiled a (static) binary with the xcompiler,
and now I'm just waiting for the kernel to transfer.

Next: dynamic binaries!
