Fixes & Enhancements
Fixes:
- Fix an issue where System and Setup password marked as 'invalid' when special characters are used.
- Fix an issue of UEFI0457 to UEFI0461 log shows incomplete strings.
- For PowerEdge R660, R760, and R760xa servers, fix an issue that PCI bus number shifts in BIOS v2.5.4.
Enhancements:
- Updated the followings:
* Intel processor and memory reference codes to IPU 2025.2.
* Intel processor microcode to version 0x639 in the 4th Generation Intel Xeon Scalable Processors Family.
* Intel processor microcode to version 0x3F7 in the Intel Xeon CPU Max Series.
* Intel processor microcode to version 0x2A9 in the 5th Generation Intel Xeon Scalable Processors Family.
- Enhance ACPI FPDT help string to indicate enabling this feature may increase boot time.
- This product release contains security update DSA-2025-156. Any security fix information will be accessible on the Dell Security Advisories and Notices website.
Important Information
- For PowerEdge R660, R760, and R760xa servers, if you update BIOS from v2.4.4 or earlier to v2.5.4, you could experience a PCI bus number shifts symptom. If your applications/script requires a fixed PCI bus number, please skip BIOS version v2.5.4.
- For PowerEdge R760 running BIOS v2.4.4 or later, if you are using the 24 x 2.5" NVMe BP, it is necessary to update BP firmware to versions 3.32 or newer. For more information, refer to this link: PowerEdge 16G: 24x2.5" NVMe switch backplane upstream link showing PCIe Gen4 | Dell US
- BIOS v2.3.5 optimizes the naming of certain PCIe cards (e.g., some NIC, channel card) to display partition number. Due to the naming change, it's expected to observe one-time PR7/PR8 message in LC log on system containing these PCIe cards, after updating BIOS to this version. (Note: PR7 - New device detected / PR8 - Device not detected)
- 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.
