Io need. If you have two or more busses, split the disks evenly across two busses. If not, just put them on bus zero. See a previous posting on how to set them up. There is really little point in splitting the boot disks from the rest, except for easier partitioning. > Do I need to configure the drives outside of FreeBSD or does the boot.flp > give options to configure the RAID options/configs? You have to use dptmgr. The boot floppy does not (yet) give you this option. > If you could make some steps on how I should go about setting up the > system, let me know and I'll probably be doing a total conversion > tomorrow > and see how it goes.

I am forwarding a copy to FreeBSD-SCSI. Others may find this useful.
