<SiI 3114 SATA150 controller> the proper way to find if RAID is supported.

[Dimiter Ivanov]

Hello, i have a Silicon Image SATA controler, which is identified as:
<SiI 3114 SATA150 controller>

It has 4 ports, and supports RAID.
I configured the RAID trough the BIOS, but FreeBSD 7.1, does not see
the RAID arrays, only 4 separate disks.

I searched the mailing lists, and there are few messages saying that
the RAID setup of this controller is not supported.

Only those messages are 3-5 years old.
I want to know where can I find a definite information, if this
feature is supported now?
