On 2000 Pro and XP Home/Pro, the option is there, but either grayed out or there's popup screen informing you that it works only on Server and up (don't remember anymore). You need to have at least Server version of Windows in order to use it. Unless of course you managed to hack something in the registry to enable it (in which case you violated licencing agreement, and sure, I'd like to know how you did it ;-). Currently, the only software RAID option for 2000 Pro and XP Home/Pro are those fake RAID controllers with their specialized drivers (I'm not aware of any 3rd party general purpuse software RAID drivers for Windows). Of course, all this holds only if Microsoft hasn't decided to unlock the feature in one of the service packs (which I doubt).
