    That's done but "free" shows essentially the same amount of memory?

    $ free
                  total       used       free     shared    buffers    
    cached
    Mem:       3095008

    I have not yet removed the original non-PAE kernels but I am booting
    to the new PAE kernel. It looks like something else is going on.
    Might be something in the bios configuration that needs changing or
    maybe this computer can't handle more than 4 gb?

    I did have, F-13 64 bit installed on it once but decided to stick
    with 32 after that for simplicity, I wanted two set up the same and
    the other box was 32 bit. That has been replaced so 64 is possible
    if I must.

    Thanks,
