What you have basically bought is a SCSI device with an IDE connector. If you're serious about hacking on ATAPI support for FreeBSD, you will want to grab the relevant specifications documents (I've got most of them at ftp://ftp.smith.net.au/doc/ATAPI,CAM) and Justin Gibbs' CAM work (from ftp://ftp.freebsd.org/pub/FreeBSD/incoming/cam-*). Kenneth Merry and I were discussing this the last week or so; I can send you various excerpts and some useful diagrams that came out of that if you're interested. mike
