Linux Not recognizing 2GB of Ram


I just noticed that under slackware 10.2 it isn't recognizing my second Gig stick. My mobo recoginizes it and it also shows up under windows. I typed free

total used free shared buffers cached
Mem: 906108 669688 236420 0 3504 549960
-/+ buffers/cache: 116224 789884
Swap: 2097136 0 2097136
vampirelord@PenguinSlacker:~$

In startup it only shows 884MB. My specs are jetway K8M8MS mobo, 2 x 1Gig ram of OZ memory. Could it be missing some option in the kernel or something I didn't setup somthing or do when I configured my system?

Yup, need to rebuild the kernel to enable highmem support. I had the same trouble but it was easily fixed

I believe for anything over 1GB you have to compile the kernel with HIGHMEM support...

Do you have a 32 bit or 64 bit CPU? If you were running a 64 bit OS this wouldn't be an issue, but with a 32bit OS you will need a kernel recompile to add high mem support (4 gig).

Thanks , yea I have a 64 bit run 32bit. I don't have highmem included because I don't have over 4GB of ram, which I thought it was only for. I guess I was wrong.

With 32 bit OS you have 3 choices, 1 gig, 4 gig and bigger... You need the 4 gig option...

I went to 64bit OS and those options are gone... Not needed any more, which is cool.

when you configure the kernel using the x menu where does it save the config afterwards.
