With which IRST driver and Option ROM?

I tested with different IRST drivers and OROMs and found that Trim for RAID0 is only working on Windows 7 (despite what the Intel Download Centre seems to suggest).

Here are some screenies from my testing.

Windows 7 + Intel RST Driver 11.2.0.1006 + OROM 11.2.0.1527 = TRIM in RAID0 works

Windows 7 + Intel RST Driver 11.6.1.1002 + OROM 11.6.0.1702 = TRIM in RAID0 works



Windows 8 + Intel RST Driver 11.2.0.1006 + OROM 11.2.0.1527 = TRIM in RAID0 not supported

Windows 8 + Intel RST Driver 11.6.1.1002 + OROM 11.6.0.1702 = TRIM in RAID0 not supported



Windows 8 + Intel RST Driver 11.2.0.1006 + OROM 11.2.0.1527 + Toolbox v3.1.1 in Windows 7 Compatibility Mode = Error

Windows 8 + Intel RST Driver 11.6.1.1002 + OROM 11.6.0.1702 + Toolbox v3.1.1 in Windows 7 Compatibility Mode = Error
