Revision 1.0 and 1.1 bios are the same you can try but the best way is to take the modules from apfel-baum firmware and insert them into revision 1.1 firmware I made you a bios mod from apfel-baum mod modules(I am not responsible for a broken motherboard)
Thank you so much! This fixed bootup issues. I always had to disable all the boot entries to be able boot and it had made every time new ones.
