For example: This assigns CAM bus 0 to the bus 1 instance on ahc1. Peripheral drivers can be wired to a specific bus, target, and lun as so: hint.da.0.at="scbus0" hint.da.0.target="0" hint.da.0.unit="0" I've never tried this w/ USB disks though. Though I will second the usage of gpt labels or glabels, those are more reliable, and will stay them same even when you move disks around, say in a hot swap enclosure... Hope this helps.. -- John-Mark Gurney Voice: +1 415 225 5579 "All that I will do, has been done, All that I have, has not."
