The latter, most likely. Otherwise, FreeBSD wouldn't see the individual drives, the RAID controller would show up as a SCSI controller and the array would show up as da[0-9]+. > (Did I just over-pay for a IDE controller?) Since you just want mirrored drives, you don't even need the RAID BIOS to boot, so: yes, you were conned. Provided you leave a little space at the end of the disk, you can set up mirrorring after you're done installing (off the top of my head and totally untested: 'atacontrol create RAID1 ad0' to create a single-disk mirrored volume followed by 'atacontrol addspare ar0 ad2' to add the second disk; you may need to 'atacontrol rebuild' to initialize the second disk; and sos@ will probably kill me for getting the instructions all wrong) > Is there anyway to get FreeBSD to recognize the LSI MegaRaid ATA > 133-2 as a RAID controller? Preferrably as a boot device? Only if its on-disk layout is compatible with the Promise or Highpoint layout. DES --=20 Dag-Erling Sm=F8rgrav - des@des.no
