Erich, I am planning on trying to use the Promise Ultra66 tonight (want to beef up performance). I currently have RAID5 running with a Promise EIDE-MaxII card quite nicely. I know about the 2.2.14-B1 patch for RAID, but which promise patch are you referring to? I see that Promise has a beta driver on their website, and this list pointed to: http://www.csie.ntu.edu.tw/~b6506063/hpt366/ which references a patch by Andre Hedrick for Ultra66 support. Which I assume is the same as you reference below. Have you or anyone looked at the beta driver on the promise site?
