UEFI 2.9 defines new event EFI_EVENT_GROUP_BEFORE_EXIT_BOOT_SERVICES, which serves the same purpose and has the timing you've described: "after the time that the timer is disabled and before the MemoryMap is finalized". Here is event description from the spec (refer to EFI_BOOT_SERVICES.CreateEventEx() section of the UEFI 2.9): "This event group is notified by the system when ExitBootServices() is invoked right before notifying EFI_EVENT_GROUP_EXIT_BOOT_SERVICES event group. The event presents the last opportunity to use firmware interfaces in the boot environment." -The information contained in this message may be confidential and proprietary to American Megatrends (AMI).
