When updating a BIOS version either under OS (by using an Update Package (DUP)) or under UEFI Shell (a .efi file), the system may take more time to complete the BIOS update process (in case of a system having 14 TB memory, it takes around 30 minutes to complete the BIOS update process under Windows Server 2016). There are two ways to work around this issue:
- Use an out-of-band BIOS update method--IDRAC GUI or RACADM CLI command.
- Physically reduce the memory capacity by removing a few DIMMs (and thus improve the speed of the BIOS update process), and then try again.
