When you try 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 that has 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 Graphical User Interface (GUI) or RACADM Command Line Interface (CLI) command.
- Physically reduce the memory capacity by removing a few memory modules (improves the speed of the BIOS update process), and then try again.

When you try installing one or more PCIe devices on the system and if the cards require more limited legacy I/O resources, then the system may adjust the legacy I/O resources between the stack and the reboot system automatically. If the system fails during the allocation of PCI resources, then a UEFI0256 error message is logged. You can perform one of the following actions and retry the operation:
- Remove unused PCIe card to free up legacy I/O space.
- Go to System Setup and disable unused PCIe card to free up legacy I/O space.

When you try installing one or more PCIe devices on the system and if the cards require more MMIO resources, then the system may adjust the MMIO resources between the stack and the reboot system automatically. If the system fails during the allocation of PCI resources, then a UEFI0134 error message is logged. You can perform one of the following actions and retry the operation:
- Remove unused PCIe card to free up MMIO space.
- Go to System Setup and enable the "Memory Mapped I/O above 4GB" option

Resolves intermittent random CPU errors such as:
- PWR2270 - The Intel Management Engine has encountered a Health Event
- PWR2271 - The Intel Management Engine has encountered a Health Event
- CPU0000 - Internal error has occurred check for additional logs
