I have modded 2 1.6 boxes with the xecuter 3 chip with I dentical results. The chip appears to work properly. The memeory bank chip turns red and boots to MS dash when the power button is held. The Memory banl LED turns blue when Power button is depress and both the red and blue LED light when the power and eject buttons are depressed simultaneously. The issue is there is no sound or video. I believe this is a different problem than posted because I never got the BIOS flash screen. Any suggestions would be greatly appreciated....Chuck
