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

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.
