Thank you for your time, akcent. If I only use your .exe as reccomended, the BIOS works but it is still Marker 2.0, not 2.1. If I extract the .exe, rename BP4100FR.136_SLIC to BP4100FR.136 and flash the BIOS, the ACPI-Support of the BIOS is broken and i have to reflash it via Fn + Esc Thank you for your help
