This package contains the Dell system BIOS update for Dell Precision Tower 7910. BIOS is a firmware that is embedded on a small memory chip on the computer's system board. It controls the keyboard, monitor, disk drives and other devices.
BIOS version A11 and earlier releases are incompatible with Intel Xeon E5-16xx and 26xx-v4 CPUs (Broadwell). To downgrade the BIOS from version A12 or later versions, you must first downgrade it to version A11. 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.
Note 1: Before updating the BIOS, ensure that you suspend BitLocker encryption on a BitLocker-enabled system. If BitLocker is not enabled on your system, you can ignore this step. Note 2: Do not turn off the power or interrupt the BIOS update process during the update.
