Fixes & Enhancements
Fixes:
- When the Memory Operating Mode option in the Memory Settings menu is set to MultiRankSpareMode, multi-bit memory errors are generated in the System Event Log (SEL) or Lifecycle log.
- The Transport Layer Security (TLS) certificate associated with the HTTPS URL is not effectively applied during the HTTPS boot operation. This issue is observed only when using the IPv6 protocol because it breaks the CVE-2021-21571 fix.
Enhancements:
- Updated the "Processor and Memory Reference Code" for the second-generation Intel Xeon Processor Scalable Family to IPU 2022.2.
- Updated the Processor Microcode to version 0x6E05 for the Intel Xeon Processor Scalable Family
- Updated the Integrate Purley Refresh PV Candidate Reference Code Version 622D07
- Updated the Integrate AEP Release 1.0.0.3534 files to Purley Refresh UEFI Source
- Updated SPS to SPS_E5_04.01.04.804.0 (IPU 22.2) for Purley Refresh.
- Added support for second source AEP persistent memory (DPN: XVY68, X06-QS). It's the minimum version of BIOS required.

Important Information
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.
- Use an out-of-band BIOS update method--IDRAC Graphical User Interface (GUI) or RACADM Command Line Interface (CLI) command.
