just found out there is a bios that works with the 1.6 on xbins pm me and i can tell yoiu how to get it i haven't tried it myself yet
Make SURE that it's M8_16.bin, not just M8.bin. M8_16.bin is the only one that will work on the new 1.6's. Check out my tut on how to resize the new 1.6 BIOS here: http://forums.xbox-scene.com/index.php?showtopic=241479
