Mine does the same thing except that i have a version 1.0 running the M8 bios, i have the M8 & M7 loaded and i get the same results. The only thing i can think of is that their is some type of key in the original Hard Drive not allowing the games to play (Halo 2). I am going to try the Configdrive 1.6 next, i have tried to copy the drives with Norton Ghost but it doesnt recognize the drives. Can the Xenium v1 os be loaded? i have tried the WD1200JB drive (120gb) and it wouldnt lock, i have a Seagate 40gb and it locked but the games still wouldnt play. can U put the original hd in and slave a second one and run the games from there?
