Windows 2000 doesn't come with an ASPI layer like the Win9x series does. The only reason NERO works is because 'ahead' released their own ASPI manager with NERO. Try Yamaha's website for an ASPI manager. If that doesn't work, try downloading an ASPI manager from Adaptec. I'm not sure, but you may need an Adaptec controller for it to work though....
You may want to try looking for a third party ASPI manager on the web... I can't remember where to find it, but I know there is one out there.
Good Luck!
