Slowly upgrading my system....

I'm about to start upgrading my system from a P111 800Mhz to probably an AMD Sempron 2800 64bit processor. I'll obviously be starting with the motherboard, CPU and memory. My plan was to swap the hard drives / DVD / CD devices straight over, then sometime later upgrade the hard drives (bigger capacity) and graphics card. What effect will I see if I take the drives as they are and connect them straight to the new motherboard / processor? I want to avoid a new install at this stage - although later I'd like to go to 64 bit. Phil -- Phil Burness Linux User since 1991 - currently using SuSE 9.3 Warrington - United Kingdom
