i discovered that some of my sparc10s are MPs, and as such can use
32meg ram sticks. what else is different, and where does the
difference lie?

32MB ram chips can be used if the OBP is high enough. It doe snot have
anything to do whether they are multi-processor machines or not (in my
experience).

If the OBP is high enough (2.25):

- 32MB RAM
- better CD-ROM support
- better CPU support

that is not what memconf says.

Indeed?

Well, then perhaps MP adds the capability to use 32MB ram. I
dinstinctly remember testing 32MB ram chips with OBP 2.12 and with
2.25.

The only difference is the number of processors installed, i.e. if you
add a CPU to a single processor machine, it is now MP - all SS10s have
two MBUS slots. You can use 64MB ram modules in any SS10, but there's no
mention of 32MB modules here:

well, i am not sure that the handbook is up to date. i am running
32meg ram sticks (lifted from an ultra-1 after i upgraded the memory)
in a recently gifted sparc10 with dual ross hypersparc 125mhz cpus.
work just fine.

since there seems to be some confusion on the subject, i will run
tests on single processor sparc10s with rom revision 2.25. see if that
is the key.


what memconf said is that both MP and SX models could use the 32s.

You need a OBP to even run the hypersparc CPUs which will quite likely
include the support I described.
