Ram
 

I have 2 GB of physical memory (RAM) and when I run "top" or "free" it always shows total: 905288 only. Can someone tell me why?

Perhaps your kernel isn't configured to handle that much RAM.

You may need to recompile your kernel to have that much ram, or maybe I'm wrong and it's just a software issue.

You should install a "highmem" kernel if your distro supplies one. Otherwise you will probably have to recompile with highmem support. Kernels without highmem support can only access around 950 MB of RAM. This is done for efficiency purposes -- handling more RAM makes the memory manager slightly less efficient, but in your case with that much RAM it would definitely be worth it.

That helped. Thanx!
