I just upgraded my laptop to 4gb of RAM, but Ubuntu only recognizes ~3.1gb, so I compiled the kernel with PAE support enabled (should support a max of 64gb).
The build went fine, as did installation, but my new kernel still only recognizes the same ~3.1gb when I run 'free'. Is there anything else I have to do so that the rest of my RAM is recognized? I am on a 32-bit architecture, so running the 64 bit Kernel is not an option (alas, it would have been the easiest solution).
I followed the build instructions here and used menuconfig to enable the PAE compile options.
Is there some bios level block on the memory? My BIOS only recognizes ~3.1gb. I am running a Dell XPS m1210 laptop, with an Intel Core Duo T2600 processor (it is pae capable).
