Yeah, after reading several posts and links provided in these newsgroups,
I realized there was no advantage (might even be disadvantageous) and
no problem, so I just removed the /PAE switch and moved on. HAD to
give it a go though.

| memory represents real ram addresses and performance improves by not having
| to translate addresses. Now that this address space is in real ram, this
| ram must be made inaccessible to user programs to prevent user programs from
| corrupting the system by writing there. Thus the system addresses are
| hidden from the user.
| I know I am not getting the description quite right, but I hope you get the
| idea. The bottom line is that just because the user cannot see all of the
| 4GB does not mean that all 4GB is not in use.
