I broke the 9227 board away from the 922x configuration because the codec changed functionally between the 9221/2/3 (found on Intel D945 boards) and 9227 (found on D965 3 stack boards). But the functionality between the 9227 and the 927x was similar enough to keep together (I only had 3 days with a 5 stack board before my contract ended). So if the 927x is being split from the 9227 code, the D965-5stack configuration needs to follow, as that is what will be detected by the preset function. I wish I had access to the new codec specs. It would have made my last week at Intel much easier. -- Tobin Davis <tdavis@xxxxxxxxxxxx> ------------------------------------------------------------------------- Using Tomcat but need to do more?
