Default Physical Address Extension (PAE) does not work on vista as expected.

Well, my goal was not to frustrate you more or make you upset with me.

My first post simply pointed out that there may be a difference in reported
memory depending on where you look: e.g. System Property may report 4GB, but
task manager may report less.
I didn't refer to BCEDIT until you replied with: "I suppose I should have
asked "what are the steps required for using PAE to actually remap
addressing to the extended areas?"

To that, I sent you to the instruction manual.
Have a nice day.

I'm amazed that you're bothering to tell me that; my original post (top of
this thread) said that I used BCDEDIT to enable PAE.

As for changing "how memory is reported" I have two conflicting reports.

Report 1) Control Panel\System: 4.0GB (2.75GB before BCDEDIT - PAE)
Report 2) Task manager "performance tab" (Physical Memory) Total 2813MB

If you're saying style-2 (task manager or other) reports won't be changed
by PAE, are you able to cite / reference a specific article? I'm curious
if this is because my signed, WHQL drivers are trying to use the same
address as a large portion of my RAM, or if some entirely unexplained
thing is going on.

As for style 1, I hate to break it to you, but control panel - system
(easily opened using [win] + [break] keys) is reporting a different
(higher) number now that I'm using PAE: it actually says 4.0 GB now!

Thanks, good idea for providing that link explaining BCDEDIT under the new
windows bootloader. I personally found it a bit confusing (was very much
accustom to using boot.ini) Personally, I like the abbreviated info (even
though it isn't official) that I found he

Note: I'm quite confused about the terms "nx" bit and "hot add" memory and
a few other terms in there. I know there was a reference in my bios menu
for something that might have been the "nx" bit... Some kind of security
feature under the same screenfull of settings that had virtualization,
disable core 1 (only use core 0) and CPU throttling.

The point is:
If you don't have more than 4GB of memory, PAE will not change how
memory is reported.

It is supported, but only through BCEDIT:
