I am under the impression that you sometimes need to upgrade your BIOS before you can install certain hardware items. I am pretty sure this is true for, say, installing the latest hard drives, but is it also sometimes true when installing newer graphics cards, or perhaps USB 2 ports, etc.? If so, how do you find out which hardware items your current BIOS can cope with, where can you obtain upgrades, and is the process straight-forward? (I am only an intermediate-level pc user.)My processor is a 750 Mz Athlon, in case this is relevant.
