>Description:

  In reviewing:

    http://www.freebsd.org/platforms/amd64/motherboards.html

  I note that the RAID is considered untested.  I've been able to
  install 6.1-R on a mirrored RAID volume.

  The BIOS and RAID utlilties were bit bit obtuse, but I was able
  to get a RAID volume up and bootable.  In the RAID utility in
  particular, you had to expressly set a 'bootable' flag for the
  boot process to see it.

  One item of note: this motherboard supports four SATA drives.  It
  has two pairs of SATA ports, usefully lableled 1-2, 3-4.  I found
  that if I used ports 1+2, FreeBSD could only see one of the two
  drives.  If I used ports 1+3, FreeBSD could see both drives.

  If I tried to build a RAID with ports 1+2, FreeBSD could see the
  volume, but only one drive, and complained a lot.

  My current config: two 250G SATA 2 drives, in ports 1+3, in a
  mirrored volume.  Snippets from dmesg:
