How about Windows 2000 SP4?Looking in device manager Win 2k is using generic IDE drivers. There's also two devices (PCI Device & PCI Memory Controller) which are unidentified because I didn't use the nForce drivers. I haven't noticed any problems as yet though, and things look more stable. Well, it's not necessary to recognize them with their exact name, but from what I know for other SATA controllers Windows doesn't start if a driver is not used during Windows install.
