Aptio V Bios cant enter setup menu

Hello guys,

i have a SBC but cant enter the Setup menu. Its a bit tricky cuz its something like a Prototype. If i try to enter the Setup than its “freezes”. Im guessing its not fully finished yet. Im using AMIBCP to change some setting. This works but sux in the long run. Is it possible that i need to change a flag or something to enter the Bios setup? There are some coustom Setups like MSI. Can i create my own?
