Hello,
by the way, I also have Intel RS2BL080 controller and it has been working for several years quite fine (in Windows 7 64 bit and now in Windows 8 Pro 64 bit) on an older Intel desktop board (D975XBX2), so in contrast to the above Intel remark on its compatibility with its desktop boards, it does work also on them, though Intel obviousloy does not officially support it.
