>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:
