Dell Update Packages User's Guide

BIOS updates require enough free physical memory to load the entire BIOS image into the physical memory. If there is insufficient free physical memory available on the system to load the BIOS image, the DUP for the BIOS may fail. To resolve, the BIOS can be updated using UEFI-based update utility or Lifecycle Controller Platform Update option, run the DUP after adding more memory or immediately after a reboot.
