If you boot undionly.kpxe then it is BIOS Legacy mode not EFI and my best guess then is a broken keyboard

There is no embeded script, and you still see "Press Ctrl-B for the iPXE command line" message?

You can test if Ctrl-B is working from the iPXE shell by using prompt

Code:

prompt --key 0x02 --timeout 5000 Test Ctrl-B && echo OK || echo timeout

So I guess, it's the typical EFI problem?

If you where running in EFI mode (which you are not) then The fact that Ctrl+ combinations is working would be enough to show that it is not The same firmware problem we have seen before.
