Hello Oliver,

As Michael suggested, I strongly suspect this is a firmware bug in your
UEFI BIOS or specifically in its CSM.  To rule out the keyboard itself,
though, just give any other USB keyboard a try, and see what happens.

There may be other workarounds available to you, too.  Try
unplugging/replugging the keyboard once you reach the iPXE menu.  If you
have multiple keyboards plugged in, disconnect one.  If you have only the
one keyboard plugged in, try adding a second one.

There might be some promise for a UEFI build of iPXE being able to remedy
your issue.  But that's about as much of a shot in the dark as my other
suggestions, and probably more work ;)

Lastly, check for a BIOS update for your motherboard. Personally speaking,
I had a problem with my system being unable to boot when my Yubikey (a OTP
device that presents as a USB keyboard) was plugged in.  Turned out to be a
known bug in my Gigabyte board's BIOS that was fixed in a firmware update
that came out before I even got the thing.

Regards,
Andrew
