Additional details

Show All | Hide All
BIOS version A11 and earlier releases are incompatible with Intel Xeon E5-16xx and 26xx-v4 CPUs (Broadwell). It is recommended that you downgrade BIOS to version A11 before downgrading from version A12 and later. This process is due to some significant changes required to enable v4 (Broadwell) CPUs. Also, along with that it enables Xeon E5-16XX and 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.
