[Anton Yuzhaninov]

Gigabyte i-RAM acts like a regular SATA hard drive at theoretically shuld work under FreeBSD:
http://www.gigabyte.com.tw/Products/Storage/Products_Overview.aspx?ClassValue=Storage&ProductID=2180&ProductName=GC-RAMDISK
 But it does not.

i-RAM detected as SATA by BIOS, but not by FreeBSD.

atacontrol list don't show this disk.
