There is a surprising amount of inconsistency in the ANSI escape codes that various terminals will generate for the lower-numbered function keys. For example: try running "cat" in a graphical terminal window, press F1-F12 in turn to see which sequences are generated, then do the same in a text console (i.e. outside of X11).

Only F6-F12 can reliably be recognised without needing to define a concept of terminal type. (F5 was erroneously added to the "reliable" list; it shouldn't really be there.) iPXE deliberately defines only the keys that are likely to work almost all of the time.
