I basically want to have the RAID 5 across ad0, ad1, ad2, ad3 , and the partitions on top of that. and then build my system on top of that (as if it were a hardare RAID controller, and I'd be installing on top of amr0s1, for example). I think this should be doable, right? So, should I 1) Boot up with Disc 1, install minimal config, reboot 2) setup GEOM RAID 5 on all the discs ? 3) edit fstab to point to /dev/[what??]/[what else] instead of /ad0s1[abef] ? or boot up with CD 1, run GEOM, build the raid 5 from here before installing anything, then install on top? thanks for your all help :) Beto
