Note

In IMM Server Firmware bundles prior to the 5.2(0.230040) release, X-Series BIOS images had major versions of 5.0 and 5.1.

Beginning with IMM Server Firmware 5.2(0.230040), the IMM and UCSM BIOS images will be common and numbered beginning with 4.3(2).

The resulting IMM BIOS Image major version sequence will follow 5.0 -> 5.1 -> 4.3 -> so on.

Overview
