Z170-a with i5 9400f

So it was first time flashing with an programmer
i have an Z170-A board and trying to put an 9400f into it
I used Coffelake mod to mod the bios
i rushed a bit and didnt backup the original bios
whats happening now is everything is spinning on the board it doesnt restart or anything but there is no video from the gpu, i think thats because it doesnt detect the bios because when i took the bios memory out its behaving the same
I put the s/n and mac into the bios using coffetime since it wouldnt work before and still doesnt

b
also i found all the information: serial, mac and uuid, will be testing a new bios chip today or tomorrow maybe this one had issues
