Once again, seconding... in this case the acceptance of Johan's generous 
offer.  As to questions of memory/slot maximums, I add another potential 
consideration.  I have several 512M PC100 SDRAM DIMMS to give away.  A 
downgrade in speed from the memory that comes with Romel's machines, but 
I have more than enough to max out a couple of servers.  Obviously the 
same goes for Johan's machines too(except  that machine may currently 
use 100s too?).

Anyways, there is that question about the machines supported maximums.  
My experience with IBMs over the years has been pleasant: many of their 
server lines(and Thinkpads too) had BIOS updates that jacked up the max 
on their old machines.  Like the old dual P2 Xeon that I currently use 
some of this memory in.  But a quick search didn't reveal any such 
updates for these machines(I was less than thorough) and I heed Jeff's 
experience with Dell. 

But I'll bring them(the memory) anyway this Saturday -- unless we 
determine that there's no way these will work before then.  Any chance 
we can arrange transport of your gear on/before that day too, Johan?

BTW, thanks all for the reading/viewing material about multi-machines 
hook-ups and edubuntu.  Let me also second the solicitations from those 
of you with more of this experience.
