Restrictions and cautions

Restrictions

The configuration import function is not available for upgrading the BIOS from a lower version to BIOS-6.00.20 and higher on HDM due to compatibility issues, but is available for upgrades from BIOS-6.00.20 and higher.

To avoid server startup errors, do not use the AFU tool to downgrade the BIOS from BIOS-6.10.XX to BIOS-6.00.XX with the user-configured settings retained.

BIOS-6.00.XX does not support EMR processor upgrade or downgrade on dual-processor servers.

Guidelines

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

If the system encounters a black screen and cannot boot after the BIOS firmware upgrade and restart, it may be caused due to the HDM firmware not being compatible. To resolve this issue, upgrade HDM to the version of the corresponding model as shown in Table 4.

Table 4 HDM firmware version for servers

As from the BIOS-6.10.48 for R6700 G6/R6900 G6, the signed firmware version is expanded to 81 M and requires an update in conjunction with HDM2-1.74 or above.

If a server equipped with Intel S4510 & S4520 SATA M.2 SSDs loses drives after a DC cold reboot, update the BIOS firmware to version 6.10.43 or later and perform an AC power cycle.

Update suggestions

This version is optional.

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.
