And I worded the queston badly, to boot. *And* as I found out later today it's an irrelevant question anyway.
What I was talking about was partitioning the whole machine - into like Dev and Prod, where Dev might get 1 CPU and Prod might get 3, etc, etc.
Anyway, I found out this arvo that it's an E250, which is an 'entry level' kinda thing that cannot be partitioned in such a way. So I only look like a bit of an idiot, not a lot. I think. Of course, I cold have just blamed it all on the guy who told me to partition the box, but that won't achieve anything.
So. Thanks for yor replies anyway - the disk partitioning stuff could wel come in handy if I get to play with the box that much - a prospet about as scary as it is cool :)
