Greetings;
New mobo, 4 core AMD Phenom cpu & 4 GB of dram. I cannot find the switch in a
make xconfig that will allow use of all of it, I am only seeing 3GB.
Am I going blind in my dotage?
Thanks.

Maybe post your .config file?

Are you using 32bit? if so, are you use PAE?

Does it all appear in the e820 map? If not, then the chipset is
probably masking it; check to see if there's any likely-looking BIOS
options to make it appear.
I assume you're compiling for either 32-bit PAE or 64-bit. If you're
compiling 32-bit without PAE (HIGHMEM64G) then the remaining Gbyte may
simply be above 4G and out of the kernel's reach.

HIGHMEM64G. Or better yet, use a 64-bit kernel.

It may be a little odd, but I have a 64-bit x86 that I'm running 32-bit
kernel. Mostly because I had some odd problems with various programs I was
using. But was what more odd was the fact that I had a little less memory
(~100mb) with a 64-bit kernel than with a 32-bit PAE kernel.
