I bought Xecuter 2.2 Pro and installed that in my XBOX. When I turned that modchiop on, it showed FlashBIOS (Cromwell) and asked for CD with Updated BIOS. I wanted to flash the modchip thru my parallel cable (6ft, 25pin). I downloaded X2BM and several different bioses. When I tried to flash it (only one bios to whole 1MB at one time) it gave me an verification error. So I tried to read it and everything was empty. I tried this several times and I still get verification error. I even tried some dos version of flash and run it thru Command Prompt at WinXP, however nothing helps. So now, when I disable modchip, evrything works well, when I enable it with all the banks off I get XBOX - Xecuter 2 (I have to erase modchip first), when I turn on the banks, it twice boots up, and then it flashes green/red on eject button. I don't know what to do. Is it possible to flash bios thru ISO CD?
