So now i tested moded 1704. But i havent SPI. I have tested flashback.. I renamed bin to creative.rom. Flashback flashed it but 00 code. So i switched to bios2 and board have serious problems to start. Must click power button on fornt panel more than 10 times and board jumps to bios2 and run. Onboard power button not responds. So then i flashback it with 1602 and board started and started twice again with "flashing bios......" text. Then started and boot. So flashback 1704 not working for me. I tested this twice with different flash drive so file may be corrupted,.. But no, it just doesnt work,... Yes i read it "Use SPI", but its just an test,..
