Upgrading BIOS to Future Versions of Firmware on Sun Fire X2100 M2 or Sun Fire X2200 M2 Servers May Overwrite User Specified BIOS Settings

To update BIOS firmware, N1 System Manager uses the default native firmware update mechanism provided by the platform service processor. For some rare upgrade paths, this default behavior may result in BIOS settings reverting to optimized defaults. Depending on the operating system and platform configuration, this may require the user to manually re-apply these settings. Refer to the server documentation for additional details on which configurations are affected.
