Hi Andrew & Michael,

in addititon, the following i can report:

- disabling lecacy usb results in a totally unusable USB-keyboard (for
menu, another i wasnt able to test).
- with usb-legacy support i can write in ipxe-shell normally, but i.e.
in the "config"-mask there are
  the same problems as in the menu

Another USB-Keyboard works fine (testet with two different types).

This might be right, but seems for me not a good solution for the problem.

We will see! Should i try some uefi-ipxe variant?

Ive seen there is an Bios-update available, will try this.
