Restart required Installed This file was automatically installed as part of a recent update. If you are experiencing any issues, you can manually download and reinstall.Fixed an Intel errata reported on IPU 2020.1 and 2020.2 where the system could potentially hang or reboot during POST when "Configuring Memory..." is displayed on the screen. This scenario may be encountered during system boot, where self-heal is attempted. The root cause is a race condition where during the self-heal process, a refresh cycle may not have completed when the CPU issues self-heal related commands to the DRAM.

Fixes & Enhancements
Fixes:
- Fixed an Intel errata reported on IPU 2020.1 and 2020.2 where the system could potentially hang or reboot during POST when "Configuring Memory..." is displayed on the screen. This scenario may be encountered during system boot, where self-heal is attempted. The root cause is a race condition where during the self-heal process, a refresh cycle may not have completed when the CPU issues self-heal related commands to the DRAM.
The Issue is described in Intel Xeon Processor Scalable Family Specification Update, SKX120 and second-generation Intel Xeon Scalable Processors Specification Update, CLX51.
- Fixed an issue where an invalid location was specified for a self-heal request. This results in self-heal not being performed, which could potentially hang or reboot the system during POST when "Configuring Memory..." is displayed on the screen.
Note: The Dell PowerEdge BIOS will automatically schedule DIMM self-healing during POST, based on DIMM health monitoring of correctable and uncorrectable errors from previous system boots.
- Updated Intel processor microcode to address the following issues:
* High Levels of Posted Interrupt Traffic on The PCIe Port May Result in a Machine Check with a TOR Timeout. The Issue is described in the Intel Xeon Processor Scalable Family Specification Update, SKX123 and Second-generation Intel Xeon Scalable Processors Specification Update, CLX52.
* Some Short Loops of Instructions May Cause a 3-Strike Machine Check without a TOR Timeout. The Issue is described in the Second-generation Intel Xeon Scalable Processors Specification Update, CLX53.
Enhancements:
- Updated the Processor Microcode to version 0x3005 for the second-generation Intel Xeon Processor Scalable Family.
- Updated the Processor Microcode to version 0x6A09 for the Intel Xeon Processor Scalable Family.

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.
