As of a few days ago I would have spouted the usual, "you don't need the 4-in-'s with XP" line. However, upon loading everything (including WinXP Pro) on a new AK31 rev3.1, I found some difficulties with driver issues on a new Radeon 8500LE and the onboard sound. After loading the new 4-in-1's I was able to clear these up in no time. Coincidence? Maybe. But for now I'd say soon after loading XP you should install the 4-in-1's. As to the BIOS, I do not agree that you should update everytime a new BIOS is released. The school of thought always has been if you have an issue that a new BIOS would address OR if there is a definate performance increase, then yes, update the BIOS. However, if you cannot say at least one of those is true then there is no good reason to do so. I think most would agree, especially given the (even minimal) chance of possible screwups that could happen when doing so.
