I thought I said that I already tried setting CONFIG_HIGHMEM64G. I didn't
upload that config, but I did try it. That config did have PAE set.
Sorry I was incomplete in my answer.

Hello Bruce,
PAE is a hack for i686 and >3GB. I'm not sure if it also means that the
hardware could limit it.
I ran across this:
https://cl4ssic4l.wordpress.com/2011/05/24/linus-torvalds-about-pae/
Even with PAE enabled with my kernel the Dual P3, with external video, has this:
Mem: 3112888 121440 2991448 556 15348 74956
I think that is because the CPU doesn't have the PAT flag.
Perhaps this is also the issue. Is there a PAE flag as well, or just PAT for
i686 processors?
Interesting article by Linus.
My processor has both pat and pae flags. My memory total is 3112844K,
which is only 44K less than yours. That's easily explained by
differences in motherboards.
I may need to break down and get a new motherboard with a 64-bit CPU.
Might be tricky though. My system is so old it still has serial,
parallel, and PS2 connectors as well as a floppy drive and PATA disks.
The logical thing is to upgrade the whole system, but that's a lot of
work that I'm reluctant to do right now.
