Which microprocessors were used on an "SGI Indigo2 Extreme workstation"? I'd
like to verify that NetBSD will run on a free machine before I accept it.

Thanks

MIPS R4x00, it was a RISC Chip.

Indigo2 systems also came with R10000 processors; anything that runs on
a R4000 should run on a R10000. If you can get the model number off the
back, the CPU type and speed can be determined from that.

Yoko Onos' former driver tried to extort $2M from her, threating to
"release embarassing recordings...". What, he has a copy of her album?

Don't forget the R8000

I have never seen a SGI Indigo2 "Extreme" with something other then the
R4x00. My PowerIndigo2 uses the r8000 and the Impact machine the r10000.

Indigo2's could have a MIPS R4x00, R5000, or a R10000 CPU in it. I think
the R5000 is correct. I know the R4x00 & R10000 are correct. I don't believe
R3000 were ever put in Indigo2's. Also nothing after the R10000 was put in
them either.

The R5000 was only used in the Indy and O2.

And while we're at it: There was no R5000 Indigo 2, but there was
one using the R8000 processor.

That's odd, because most R8000 systems were sold with Extreme
graphics. What does your R8K system have?

Btw, though implicitly already mentioned, don't forget Indigo2 can
also use
the R4600SC/133 (I have two of them). Rather rare, but kinda cool as
they
gave better int speed than R4400 (about the same as an R4400SC/175)
though
at the expense of fp.

I have 3 R8K systems (two are dead though) and all did come with
XZ graphics installed. One has even the Power/XZ badge still installed
on it.

An Indigo 2 R4600 sounded like a usenet myth to me for a while
until I managed to hunt one down.

Do you know what's wrong with the dead ones? I have one unit that's
missing parts, so maybe
we could put together a working unit?

I guess they must have been for customers who just wanted the crunch
power,
or only limited visualisation needs.

It's certainly a CPU config that SGI never mentioned much. Can't
imagine why.
Pity really, an R4600SC/250 with 1MB L2 would have been a nice system
for
int performance, general apps. I guess by then the R10K looked like a
better
idea.

Hmm, I wonder if it's possible to clock up an R4600SC/133 in Indigo2?

I'm not really sure and I don't dare swapping parts with the known good
one. I know that I probably pushed one of the CPU modules over the edge
by playing with it / trying to reassemble it.

What is your unit missing? Maybe that is a non-critical part. The
mainboard is probably less failure prone than the CPU module itself.

There were docs on it on techpubs though, I think.

Probably noone ever tried, just like you said... the R10K sounds like
a better idea for all purposes.
