I recently tried to install a mod chip but gave up soldering the bios. I finally cleared the links between the terminals on the bios chip. Now when the ps2 starts, the sound is very muffled and digital sounding and it cannot load any DVDs/Games. When I put a DVD in, it starts to read it and then says "DVD Player is not Configured". When I put a game in it trys to read and then says "No Data". The only thing I can think of is I got the bios chip too hot when i was soldering and fried it. Let me know if anyone else has had this problem and any ideas of how to fix it.
