Take note as well that the Controller has an ID as well.. typically 7 from what I understand. Also, a handy thing to keep in mind for the future if you use ID 6 and then add another drive later (with a lower ID) is to wire down the drives in the kernel.... See the section in LINT (typically in /usr/src/sys/i386/conf) that begins with # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so # that a given bus, target, and LUN always come on line as the same I did that today on a system... Very handy! For complete details, check the FAQ... The reccomended way seems to be going through /stand/sysinstall and choosing custom/Express... But again, check the FAQ for instructions. ---Mike
