Ok guys, I had enough trying to get contact with that d0 pin. I soldered all pins and believe me, there is 100% contact on every pin. All wires are connected correctly. Im able to flash the bios correctly and to set the dip switches. But the problem is the flashed bios is not working. I tried every fucking bios X2 (256/512), M7, D6(with and without EF). And every format combination. The bios is just not booting. I really need help. I think there has to be something wrong with formatting the chip, it is definately soldered correctly. Thanks in advance
