Oh, it doesn't drop to the prompt. The Wiki said that it should drop to
the prompt if FAI is working (without having the target system config
properly set up).

Instead, the error message appears and then the system immediately boots
from the next boot option (Hard Disk).

unfortunately, the result is the same. System shows the error message,
then proceeds to boot from disk.

I've also activated the --verbose option of tftp on the server and it
gives this output in the logs

So it seems that something weird is happening on the target machine,
before/while the kernel is loaded...


My Google searches showed that this problem has appeared every now and
then in the last 10 years for people trying to boot over pxe. Somewhat
dishearteningly, not a single one of the people asking questions about
it on forums managed to get it fixed...

I'm grateful for any further suggestions.

Best regards,
Daniel
