There are many references on the web talking about increasing default user address space to 3.5 G however lacking specific instrcutions. 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? thanks in advance. P.S.
