Probably not using all 4GB of memory.  The 32-bit desktop version only
recognizes 3.5GB, so you lose .5GB.  To fix it, just install the server
kernel after you've loaded the desktop.

The only thing that hacks me off about the 64-bit version is that in C,
the change should have been made to a 64-bit integer instead of 32-bit.
 If you want to have arrays larger than 32-bit, you have to segment
them.  Guess it was not considered important on these toy computers anyway.
