Have plans to replace my MB, memory, CPU and video card but keep the current 2 hard drives, CD rom and CR rom rewriter. Will I have to get into bios? If so,,,,how is it done and can some one guide me through it. I have the Asus A7N8X MB and the manual that came with it, but doesn't tell you alot about bios. I have in my current system 2 hard drives. My master and then the slave. On the slave I have alot of pics I don't want to loose.
