I have a xbox v1.5, x2.3b Lite +, X4981.06 , Evox 3935, upgraded to 160 GB HDD. Everything was running fine, until I tried to play Max Payne 2, orginial xbox game. The game freezes during "loading.." of level 1. someone told me this is due to a wrong clock setting in MS dashboard. When I DISABLE my chip, I get Error 21. When I select "MS Dash" from Evox Menu, I get Error 21 ! Is there any easy way to fix this ?
