Andy, My Maxtor 7,200 RPM drive came with an ATA/100 Controller Card, which is what you're asking about here. When I went to install the Win2000 part of my dual boot system (Win98SE/Win2K), I had to have the drivers for the Controller Card handy. Without them, WinXP (like Win2K) won't be able to set itself up to boot from the drive properly. And YES, you'll have to make sure that the card you buy is WinXP compatible (or at least that the manufacturer has since released drivers that are WinXP ready). Even if the card is made for WinXP, check the manufacturer's web site to see if they offer newer drivers than the ones originally included with the unit. If they do, use those instead since they've probably worked out some bugs and possibly will allow the card to run faster than the original driver set. You'll also need to go into the BIOS and let it know that the hard drives are no longer on the regular IDE busses. If it's available, use the Auto-Detect Drives option and the BIOS will do the work for you. Other than that, I had no problems at all with the install or the running of the OS since then. Note that I don't have anything at all attached to the mainboard's IDE busses. The Maxtor and another hard drive is on the first IDE bus and my single CD-R/RW drive is on the other.

I'm running XP Pro, so do I need to look out for one that is XP compatible?
