Claude, Thanks for digging into this a bit. I just added some code to make it easier for applications to detect at runtime if ATA_CAM has been configured in the kernel: http://lists.freebsd.org/pipermail/svn-src-stable-9/2011-October/000114.html I am not 100% sure how the CD driver works with ATA_CAM. I think you might need to look at: src/sys/cam/scsi/scsi_cd.c and also read the cd(4) man page. We may need to extend scsi_cd.c, but I'm not sure. -- Craig Rodrigues [email protected] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[email protected]"
