I agree. 2.4 runs like a charm on 4/300 and 4/400 systems.

That sounds wonderful. Although, I'm a big fan of 2.6 myself so... :-)

What do you mean by the old Ross' CPU modules? From the webpage on
false.net it says clearly:
"It can be made to work but only if it is an MP system (not the older
CPU's)."

My memory reminds me of a discussion here some months ago about older
and newer revisions of the SM100 Ross CPU modules. The older ones (rev
7?) didn't support MP, but the newer ones (rev 8?) do. We currently have
a 4/600MP system with dual-SM100 rev8 CPU modules, runs SMP fine, so
should I rely on the text in that matter?
Although, the example on the webpage was a 4/600MP with dual-SM51's, so
that should be a good reason to rely on the fact that SM100's isn't
supported at all.
But then again, why should Sun drop support for CPU-modules?

I guess that makes sense in what people say that "the SS600 is
considered a rackmounted SS10"...


BTW, is there anyone out there with 4/330 Memory Boards leftover? You
know those small, 6U VME boards that couldn't be fit anywhere else?
Since the 4/330 is lacking VME-slots, I'd be happy to expand my 4/330
past the 32MB RAM.
