Hi:
I am running Redhat Linux Enterprise version 4 update 4 on a dual-core
4G memory machine.  There are many references on the web talking about
increasing default user address space to 3.5 G however lacking specific
instructions. My questions:

1. What is the specific steps to be done for the kernel to support 3.5 G address space? 2. Do I need to re-compile kernel to make this happen? If so, any specific instruction?

If this is a dual-core box then quite likely it also supports 64-bit, that would be a much safer option than messing with the kernel/user split and reducing the kernel memory available so much.
