these drivers came out in early Feburary 2005 --> VIA_IDE Accelerator_V120b.zip http://www.viaarena.com/downloads/d...rator_V120b.zip supposed to accelerate the ide controllers. Reported problems / effects: 1. HDtach does not recognise driver 2. Seems more responsive / stable 3. Gives more info on drives. 4. Problems with optical drives, eg. burning (similiar problems as the old nvidia ide drivers) 5. Other benchmarking programs --> unknown Recommendation : install oni if u have chipsets kt400 or newer.
