I have a DMS3 that just won't work

It's set up perfectly...but acts as if no mod were installed

edit:

This is a V7 MoBo

umm are u sure umm. N mode works jsut like no chip is installed. Check your bios wires and also check your c wire also check yoru power and ground wire. after u check them and they are good hopefully u did somethign wrong and corrected it. Now your ps2 should have modes and featuers. if it has modes and boots up psx backups but not ps2 cheack the cd dvd points
