    Restrictions and cautions

    Restrictions

    Due to Server restart mechanism optimization, the BIOS firmware will not retain configurations when downgrading to a version below 7.00.25. To restore the original configuration after downgrading, you must export the configuration file of the current version through the HDM interface before downgrading, then perform a forced overwrite downgrade using the target lower version. After the downgrade is completed, re-import the previously backed-up configuration file to complete the configuration recovery.

    Guidelines

    To avoid BIOS boot failures, do not upgrade or reset HDM during BIOS boot.

    In BIOS-7.00.11 and later versions, the options for the PCIE Network Configuration menu cannot be properly configured and retained. This issue is resolved in BIOS-7.00.21 and later versions.

    Update suggestions

    This version is recommended.

    Update restrictions and guidelines

    Make sure the software versions are compatible with each other.

    To update both HDM and the BIOS, update HDM first.

    Make sure the server is running in stable state before the update. That is, the server is powered off or has entered the operating system.

    If the server enters the OS before the update, you must power cycle the server for the new firmware to take effect.

    If you select the Retain or Restore method to update the BIOS, the update occurs during POST after the server is powered on again. During the update, do not disconnect the power source from the server, or forcedly power off or restart the server.

    If you select the Forcedly restore method to update the BIOS, do not disconnect the power source from the server, or power off or restart the server.

    Selecting the Restore or Forcedly restore method will restore the default BIOS settings, including restoring the boot mode in the BIOS to the default (UEFI).

    During BIOS update with Forcedly restore selected, writing BIOS data, such as restarting the system or saving BIOS configuration from the BIOS setup utility, can cause data write errors. This can lead to BIOS ROM integrity check failures and even system starting failures. If the system prompts Flash Image Broken! System Halt!, forcedly power off the server, and then try to update the BIOS with Forcedly restore selected again.

    As a best practice of bulk update, make sure you can update one server successfully before you update the remaining servers.
