They were put in place to ease the transition away from the old ATA drivers between 8 and 9.

A good thing to try; also why I suggested a distribution kernel: rule out your build process entirely. -- Fuzzy love, -CyberLeo Technical Administrator CyberLeo.Net Webhosting http://www.CyberLeo.Net <CyberLeo@CyberLeo.Net> Furry Peace! - http://www.fur.com/peace/
