when you press the eject button, the xbox boots with the original bios. since you have the evox dashboard installed, the original bios tries to load it when it runs but it fails (original bios can't load unsigned files). therefore, you get flashing lights and a service error. to boot with the original bios, you need to either get rid of the evox dashboard, or flash your pc-bioxx with a bios that loads the yboxdash.xbe file...that way you can leave the original xboxdash.xbe, and rename the evox dash to yboxdash.xbe.
