PAE turned on on Slackware 14 32bit SMP?
 
I am trying to definitively find out if Slackware 14.0 has PAE turned on for the 32 bit distribution.

The release says this:
Quote:
On the 32-bit side of things, there
are both SMP (multiple processor capable) and non-SMP (single
processor) kernels. The non-SMP kernel is mostly intended for machines
that can't run the SMP kernel, which is anything older than a Pentium
III, and some models of the Pentium M that don't support PAE. On
32-bit, it is highly recommended to use the SMP kernel if your machine
is able to boot with it (even if you have only a single core) because
the optimization and memory handling options should yield better
performance.
However, I have 8 gb in a motherboard, and only 3.3 gb is showing after boot. Yet running memtest, 8gb shows. I searched /proc but didn't find anything which would indicate PAE, except that kcore had a string which matched, and I don't consider that definitive one way or another.

Alternatively, can someone tell me where I might determine that PAE is on for a given kernel?

Thanks.

The SMP kernel has PAE enabled. If you want to determine the status of PAE for a running kernel try it with
Code:
zcat /proc/config.gz | grep PAE

Thanks, exactly what I was looking for. Didn't realize that the config was there.

had some problems with this when i helped a coworker earlier last week, so installed Slackware 13.37 instead even if its EOL
