You list your BIOS version as "B.11" but that's not the typical=20 nomenclature for BIOS on this board; the current BIOS version is 0050=20 with the full version string being TMIBX10H.86A.0050.2011.1207.1134. I'm wondering if you may need a BIOS update. Also, are you booting in=20 EFI mode or BIOS mode? -hpa --=20 H. Peter Anvin, Intel Open Source Technology Center I work for Intel.
