Symptoms

A 14G PowerEdge server with BIOS 1.5.4 (1.2.2 for the R840/R940xa) installed and with TPM installed, enabled, and configured, may fail to install a Windows BIOS DUP package from within Windows 2016 or 2019.

BIOS updates using iDRAC, EFI, or LifeCycle install successfully.

Resolution

Engineering is aware of this issue.

The permanent fix for this issue is in the newer BIOS versions that is on the support site. 

 

Note: The first BIOS updates attempted (any method) after a failed OS in-band BIOS update, will also fail unless the server is warm rebooted first after the failed update.



With the server running the affected BIOS version, to prevent the in-band Windows BIOS DUP install failure, there are two solutions:

  1. Disable TPM and then install BIOS version 1.5.6 (1.2.4 for R840/R940xa) or newer in-band. Reenable TPM once the BIOS update is complete.
  2. Install BIOS version 1.5.6 (1.2.4 for R840/R940xa) out-of-band using EFI, iDRAC, or Lifecycle Controller.
Note: The first BIOS updates attempted (any method) after a failed OS in-band BIOS update, will also fail unless the server is warm rebooted first after the failed update.
