I picked up a Challenge DM as well. When I'm done with this box it will have 12*R10000 w. 2MB L2 and 2GB RAM. So this is a work in progress. I rearranged the RAM a bit to improve interleaving, and to get some confidence wanted to run the diagnostics. I get:

Is it possible to use more than 4 cpus (1 nodeboard) in a Challenge DM? :shock:

I think jan-jaap was talking about getting the Challenge L up to 12 cpus. A Challenge DM can only go up to four cpus.

I think jan-jaap was talking about getting the Challenge L up to 12 cpus. A Challenge DM can only go up to four cpus.

Indeed. My intention is to transform the 'L' into the ultimate build system for old IRIX versions: running IRIX 5.3 with 12 R4400's or IRIX 6.2 with 12 * R10K's (with 2MB L2!). I already had two quad R10K IP25's, one in my Onyx, one as a spare. Now, with the 'DM' I got number three. In the 'L' was a quad 250MHz IP19, and again I had one already plus a quad 200MHz.

I'm currently just taking inventory of what I picked up, what works and what not, board revisions etc. Tonight I'll pull the 'downrev' IP19 and run diagnostics on this system, them I'll move on to the DM.

I'm kind of curious where the built-in limitation (single CPU board) of the DM is hiding -- backplane? system controller?

I have no intention to keep both systems around. If someone wants the Challenge DM, I can probably create a working system from the dual CPU board. Otherwise I'll dismantle it and keep all the power bricks, system controller and boards as spares / donors.

Next, I'm going to install a second IP25. This should fail on a genuine DM, but I cannot find any difference between the system controllers of the DM and the L The L booted fine with the system controller of the DM, with 8 CPUs installed ...

Booted the 'DM' with a second IP25 this evening, and got:

Code: Select all


   >> hinv -b
   

   

   System Bus Information:
   

   Slot 1: MC3 memory board with 512 megabytes of memory (Enabled)
   

   Slot 2: IP25 processor board with 4 cpus (Enabled)
   

   Slot 3: IP25 processor board with 0 cpus (Enabled)
   

   Slot 4: IO4 I/O peripheral controller board (Enabled)
   

   Slot 5: IO4 I/O peripheral controller board (Enabled)

The '0 cpus' raised my blood pressure for a moment (as did the B+++ text on the LCD), but it turns out both IP25's work fine as long as they are in slot 2.

Guess I have to look again at what limits the DM ... but I have many other things to do so this project will be suspended for a short while.

Oh, and I tried again with the system controller of the Challenge L -- same result. Will have to inspect the backplane ...

Not possible, at least not in a deskside. Only 5 E-bus slots, and you need at least one for memory, and one for I/O. So max is 3 CPU boards. I'll have to settle for 12 * R10K 8-)

But they will be the 2MB L2 model.

Yep, you need a Challenge XL refrigerator, um, rack, to go past 12 cpus.

rumors are, that there is a screw on the backplane present on the DM that disables all but one ebus slot for CPU boards...
That said, I do have a DM running with more than one CPU board. I just can't say why it works, because I got it in that configuration.

Don't suffer from insanity...

OK, my bad, I've had 12 proc system on my mind

According to lunatic it's possible so I'm really excited how it could be done.

Me too. It's just a curiosity thing; I have both the L and the DM sitting here so this is the perfect occasion.

I could simply install the R10K boards in the Challenge L and call it quits but that wouldn't be satisfying. I need to know how things work and how to hack them
