Try on one of those spare laptops:-)

you funny man.  :-P  actually, it wouldn't help since all of those
laptops have 64-bit AMD CPUs so PAE doesn't come into play.

AMD-64 is, I think, a superset of PAE, so PAE would br right if you install 32-bit.




My ThinkCentre's CPU (P IV 3.0 Ghz) says it supports PAE, but I
don't have a PAE kernel installed, though they are available.

the actual issue is that, if i have a 32-bit, PAE-enabled system with
<4G of RAM, obviously, PAE won't be relevant and i'll get a regular
kernel installed.  but what if, even though there's <4G *now*, i know
that i'll be putting in several gig next week, so i'll want the PAE
kernel in preparation for that?  better yet, does it hurt to have a
PAE kernel even if you don't need the PAE functionality?

When I replied earlier, I ran dmidecode to see how may RAM slots I have. I can install 4 Gbytes, but as I understand things I don't get to use it all unless I use PAE. But I could be wrong, I might not get to use it all either way.
