A11 and all earlier BIOS releases are incompatible with Intel Xeon E5-16xx/26xx-v4 CPUs (Broadwell) , Customers who wish to downgrade from A12 (minimum revision to support Broadwell) or higher must first go through A11 before going to their target BIOS rev. This is due to some significant changes required to enable v4 (Broadwell) CPUs and at the same time allowing Xeon E5-16XX/26XX v3 (Haswell) CPUs and v4 (Broadwell) CPUs BIOS to stay in one BIOS stream. All versions of the Broadwell CPU enabled BIOS (A12+) understand how to migrate the Haswell settings. There are no upgrade restrictions. To downgrade below A12, a user must flash to A11 first. It is the only V3 (Haswell) BIOS with v4 (Broadwell) downgrade logic in place.
