I have re-read all of your posts and I now understand that you want to wire down bus, target and unit. It is my understanding that the device.hints will wire down the device (i.e. /dev/sa# or in my case /dev/da#). I played around with my system with the external firewire drive and as long as I have the lines in device.hints the 0-0-0 is reserved for the drive whether it is plugged in or not. The optical drives remained at 2-0-0 and 2-1-0. I then plugged in a USB thumb drive and rebooted. This forced the optical drives from 2-0-0 and 2-1-0 to 3-0-0 3-1-0 respectively. I then plugged in a USD card reader and rebooted. This forced the optical drives to 4-0-0 and 4-1-0. I thought about this for awhile and looked at dmesg again. I then edited /boot/device.hints as follows ### Wire down external hd to da0### hint.scbus.0.at="sbp0" hint.da.0.at="scbus0" hint.da.0.target="0" hint.da.0.unit="0" hint.scbus.1.at="ata1" #optical drives on the second ata cable. hint.cd.0.at="scbus1" hint.cd.0.target="0" hint.cd.0.unit="0" hint.cd.1.at="scbus1" hint.cd.1.target="1" hint.cd.1.unit="0" this forced the optical drives back to 1-0-0 and 1-1-0 no matter what other devices are plugged in.
