I am going to be reinstalling XP (done with my test run and want a clean install) on my P4b533-E and am debating about using the onboard raid controller or the regular ide controller for my drive, a few people have said that using the onboard raid (even if you are using a single drive and not actualy running a raid array) is a bit faster then the regular ide ports. Also I have seen people suggest flashing the bios of the promise raid controller to turn it into a full fledged raid controller or just a ultra 133 controller. I am cursious as to what people think about this. Thanks.
