thx to coolpal and alle the others. tomorrow I`ll play, like a friend of mine said to hacks, "eisenbahn" .. I orded a fresh Transcend Jet Flash and an bottle of wine
it would be usefull to have an config.plist. in the past I run uefi clover with great luck but very poor/little knowledge. often my board sucks in the early bootphase. no usb-keyboard, no F10 or "enter the bios" seems to be a .dsdt problem.
I have to find out the rev of the board. is the a hint on the board for old people like me without a loupe? I will test the patched bios it differs from the mb_bios_ga-z68x-ud3h-b3_u1l and I hope it will be better. any more infos about it?
