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.
