I have used rufus 2.11 to create a bootable USB drive from fwj963usa.iso. Then disconnected everything from the device. Attached the USB drive to Port 1, front left. Plugged in the Power.
It still beep, then I removed the USB Stick and it stopped beeping.
Second try: disconnect everything, plugged in the Power connector, attached the USB drive, still beeping
EDIT: Can anybody point me to the hardware maintenance manual of the M900

You need to download the hardware maintenance manual and follow the instructions
As I said, although you have the M900x, the correct steps are in the M900 HMM.

I saw it in the m900 documentation but on my motherboard is for the CMOS Clear Pin's no numbering visible on the PCB there are 4 Pin's. I try to avoid breaking the board completly when I set the Jumpers wrong. I found no schemas for this motherboard.

Here you can see the Pin's (red background): http://i.imgur.com/sG0nwLv.jpg
The Jumper was set by default to 4/6
I set the Jumper to 2/4 as noted on the PCB (didn't saw it first). Then connected the USB Stick, then the Power cable and the M900 boots automatically with the two short beep codes and a blank screen.
Next step: I will test the USB Stick with qemu
EDIT: Also a USB Stick made with "dd" did not help

There I have to buy a USB DVD-Drive and have to take the customers workstations :-(
But if there is no other way. I will report back in about two hours.
In the meantime the M900 changed his beep code.
The CMOS Clear jumper is on 2/4, the USB Stick is plugged into Port 2 (front right). Now it beeps two time short, wait, two times short, and then a long time no sound and then repeat from start

The zip file at the bottom contains instructions for creating a boot flash drive for a M93 Tiny, I have not see the equivalent for the M900, but that may provide the correct method for creating a bootable drive for a ThinkCentre without DVD drive.
