*.efi is "iPXE as an EFI application".  It generates something which you can 
run by typing its name in the EFI shell.

*.efidrv is "iPXE as an EFI driver".  It generates something which you can load 
using the "load" command from within the EFI shell.

*.efirom is "iPXE as an EFI driver, wrapped up in a ROM image".  It generates 
something which you can include within a PCI expansion ROM BAR, and which will 
then be loaded automatically when the system is started in UEFI mode.
