In your kernel config file, you can specify the controller that sd0, sd1, etc attach to. Look at the scsi.4. You'll have to temporarily disconnect the second bus of disks so you can boot and recompile your kernel. > Stephen >-- >The views expressed above are not those of the Worker's Compensation Board of >Queensland, Australia. > > -- Justin T.
