Yamaha has new drivers out for their DS-XG products which are based on these chips: YMF724, YMF740, YMF744, YMF754. The version number is 5.12.01.5244. These drivers reportedly also work under Win2K. Uncertain is the support of 3DSound and EAX as Yamaha has been known to lack those features in previous Win2K drivers. Yamaha based soundcards are syndicated by Hoontech, Aopen, Guillemots Fortissimo (Hercules) and Addonics. These reference drivers can be downloaded here: Yamaha WinXP Drivers 5.12.01.5244 5,068 KB.
