After I pluged off all devices - except CPU and one RAM modul - I just tried another RAM modul to be sure that this curiosity is not caused by the RAMs. I'm using a Samsung SM951 with 512 GB as M.2 with an installed Win10 PRO system Like I said.. with BIOS v1.20 all is working and the OS is booting up. I just tested v2.xx. It causes the same like v7.20 .. freezing with code 99. I cannot do any keyboard actions until I do a hard reset. If I'm quick enough, I can press F2 to enter the BIOS. But dunno what I have to change there to get this working. SATA3_0 and SATA3_1 is not in use. Only CPU, 1 RAM and the SM951. When I remove the SM951, the system will activate the BIOS automatically. I supose that's okay because the board can't find any storage devices.. dunno.

Wait... wait...

Your first picture show the prompt to enter the BIOS, Press F2 or DEL, right? That is the normal prompt seen after updating the UEFI/BIOS. I've seen that screen 100 times.

The 99 code should mean nothing. If you are prompted to enter the UEFI/BIOS, POST completed successfully.

For some reason, your keyboard is not responding after any BIOS update after 1.20. Do you have another keyboard you can use?

What keyboard are you using? I assume it is connected to a USB 3.0 port? Is it wireless? Try putting the keyboard connection into another USB port, such as one at the top of the IO panel.

Yes, when the SM951 is removed, there is no boot device, so it takes you directly into the BIOS.
