Don't count on that, the 4GB thing is a very very rough and

Just because a machine has under 4GB of ram does not mean that
the PAE kernel won't give you more memory. The bios *CAN*
(some do, some don't) remap something that is covered by a
video card, or otherwise reserved for something to above 4GB
requiring a PAE kernel to use it. And this can start
happening at around 3GB of ram or more, the only way to know
if PAE is correct for a given setup is to either know exactly
what the bios is doing or to test it.
It all depends on exactly what the bios is doing, he would
need to boot a PAE and a non-PAE kernel and check how much
memory is being seen by each, if they are the same or really
close (within 100MB) I would avoid the PAE kernel.
Interesting... I'll make this a keeper and test soon. I build
most of my machines with 4GB of ram now, but that's in Windows
land at work - they tend to filter my way as older ones are
superceded or retired - my current Linux machines all top out at
3GB
I'm am afraid that it is beyond my qualifications to start kernel
management. First I must
know the difference between these kernels, hwich I dont. It seems that
I need to take a course
in advanced Linux to embark upon a venture like that,.
So for now I'd better be happy with the two optional screen resolutions
that I have,
and the 800x600 is not bad at all, I can live vith that without someone
holding a gun to my head.
Now, I happened to find
ftp://download.nvidia.com/XFree86/Linux-x86_64/1.0-8174/README/64bit_html/index.html
NVIDIA Accelerated Linux Driver Set README and Installation Guide
*googlig for the nvidia-xconfig.

*It is a lot of stuff here that I have to spend some time on, and
hopefully I will be
better equipped to handle this.
