I'm not sure what is going on. Halo 2 will not play on my moded xbox. There are a few other games as well that will not play. When my son tries to play Halo 2 or the other games, the box reboots right after starting the game, either from the disk, or from the harddrive. My only guess is a bios issue. I got the xbox moded, It has an xecutor chip, but I don't have any idea what bios version it has, or what the best bios should be.
Any suggestions on what I should do to solve this problem?
