When I try to flash EFI firmware on Intel Pro/1000 (both single and dual port) I get Error: Flash too small for the image

Hello,

I have downloaded both the 20.7.1 and 22.0.1 version of firmware update and tried to update the ROM from PXE to the EFI ROM.  Under both Linux and a UEFI shell, it fails every time.  This occurs both on a dual port Pro/1000 and a single port.  The Linux output is:

[root@testsystem BootUtil]# Linux_x64/bootutil64e -nic=2 -up=efi

How do I flash an EFI ROM on this cards?  I can flash the PXE ROM on them, but not the EFI ROM.

Thanks in advance,
