Fixes & Enhancements

Fixes:
- Enabled the PCIe Data Link Feature Exchange option as the default setting for all CPU root ports. This improvement can address lower bandwidth issues observed on certain GPUs, such as the NVIDIA H100 when connected to CPU PE0, PE1, and PE2. Furthermore, it resolves performance failures, such as those encountered during the "Integration PCIe" test in the Intel XPU diagnostics tool.
- The performance issue with the NVIDIA GPU RDMA micro-benchmark has been resolved by disabling the ACS (PCIe Access Control Services) feature when the Virtualization Technology option is set to Disabled.
- Fixed the system randomly shutdown issue during the warm boot cycle test when USB is enabled.
- Corrected Slot Type field in PCIe Slot Details in iDRAC web Graphical User Interface (GUI).

Enhancements:
- Added a new toggle-button option called the IIO PCIe Data Link Feature Exchange in the Integrated Device sub-menu of the BIOS setup. This knob can be set to disabled to support certain legacy PCIe cards, such as PCIe Gen3 Intel FPGA card. For more information see, Intel Arria 10 FPGA PCIe 3.0 Endpoint is not compatible with PCIe 4.0 capable system.
- Added the password customization feature. It enables users with the ability to enforce additional requirements for new system and setup passwords as a mean of improving security for accessing the BIOS setup. Two new BIOS Setup items were introduced under System Security sub-menu:
Strong Password Status
* Options: Enabled | Disabled
* Default: Disabled (so there is no effect on existing users)
Strong Password Minimum Length
* Options: 8 to 32 characters
* Default: 8 characters
- Supported "Optimizer Mode" feature under BIOS setup "Processor Settings page to have better performance for the following platforms. The iDRAC version needs to be v7.00.60.00 or newer version:
* Added R960 with air cooling
- The PowerEdge XR8610t and XR8620t Projects Telco related profile settings have been fine-tuned. For customers who have already applied the "NFVI FP Energy-Balance Turbo Profile" or "NFVI FP Optimized Turbo Profile" setting in the BIOS setup "Workload Profile", please follow these steps: Change the 'Workload Profile' to "Not Configured", exit the page, and save the setting. Then revisit "System Profile Settings" to re-configure it.
- Supported new TPM 2.0 module.
- This product release contains security updates. The information will be made available on Dell Security Advisories and Notices.
- Updated the followings:
* Intel processor and memory reference codes to Post Launch Release version 4 (PLR4).
* Intel processor microcode to version 0x4d0 in the 4th Generation Intel Xeon Scalable Processors Family.
* Intel processor microcode to version 0x290 in the Intel Xeon CPU Max Series.
* Intel Trusted Execution Technology (TXT) BIOS AC Module and SINIT AC Module to version 1.1.7.
* Intel Server Platform Services (SPS) and Manageability Engine (ME) firmware to SPS_E5_6.1.2.048
* Integrated Dell Remote Access Controller (iDRAC) HII settings engine to version 5.00.00.17
- Added the Opportunistic Snoop Broadcast feature. It is a feature within the PCIe protocol that enhances system performance by reducing latency and improving data transfer efficiency. Auto is default and controlled by SI Compatibility and Directory Mode Enable/Disable; same as the previous BIOS 1.5.6. Three new BIOS Setup items were introduced under Processor sub-menu:
Opportunistic Snoop Broadcast
* Options: Enabled | Disabled | Auto
* Default: Auto
- Optimized Power Mode Setup item is not shown for Edge Enhanced (EE) CPU. This BIOS Setup item is under System Profile Settings. Intel CPU formerly Sapphire Rapids Edge Enhanced does not support Optimized Power Mode.

Important Information

- When upgrading the BIOS from version 1.0.1 to 1.2.1 or a newer version, encountering the UEFI0074 message during the initial BIOS POST and in the Lifecycle (LC) log is a normal occurrence.
- Please use DUP file to update BIOS in OS or iDrac GUI if Intel Xeon CPU Max Series is installed on the system. The BIOS update cannot be performed using .efi utility due to a CPU limitation.
