But, there are the CAM and CAM-3 specs: http://www.symbios.com/x3t10/io/t10/drafts/cam/cam-r12b.pdf http://www.symbios.com/x3t10/io/t10/drafts/cam3/cam3r02.pdf I think the way to go, if you want to add IDE support to the FreeBSD CAM code, is to write another transport layer to go alongside the current transport layer. Justin can elaborate on it a little more. (I've CCed him..) Ken -- Kenneth Merry ken@plutotech.com
