I installed with the 2 disks connected to the controller that was found
by Freebsd. Then I added siis_load="YES" to /boot/loader.conf.
Power down the machine and connected 4 drives to the 3124 controller.
Upon restart I created a RAID5 set with the 4 drives in the controllers
bios. Booted into FreeBSD but the RAID5 was not detected only the
This controller obviously does not work as expected. I need a suggestion
on a not to expensive RAID controller that is supported by FreeBSD so
that I can get the RAID5 set to work.
