kernel compilation for supporting more than 1 GB RAM size

Memory Size

This is the main reason you should know how to compile a kernel. Some default kernels will only allow up to 4GB of RAM. Currently I've only noticed this with Fedora Core, Debian and non-servercd CentOS distros. So be sure to browse to the following section:

Processor type and features --->
(And look for...)
High Memory Support (4GB) --->

Change this to 64MB to allow for 4GB and higher RAM.
