Hi everyone. I got a mod bios EPROM from fleabay (incl. the original bios). I threw the mod bios on the socket, bridged jp1, removed any cf card and fired up the cab. I don't get greeted by any update screen. I just see four vertical color bars and that's it. Any hints on what I am doing wrong? If I start the cab without an eprom installed on the mainboard and have jumper 1 bridged I get an error message (bluescreen) - so the flashing mode triggers. Attached some photos:
