Well I have gone over the connections with a multimeter and even resoldier a few that I thought may have been suspect, but still no joy. Should I be getting a red screen of death when trying to boot my originals without disabling the chip? Should I not be getting the red screen of death when trying to boot my back up as well? I am using a soldering shematic that I found off of modchip.com (V4 no gap bios). From what I am explaining can anyone tell me which connections sound like they may be wrong. It seems like I can disable the chip well enough so the pwr, gnd and rst are probably working. The only ones that I have questions about are the S connection which appears to be made between two componets maybe a capacitor and a resistor, the A connection which appears to be made off of a leg of a resistor. I have been able to track the continuty of the A,B, and I connections back to legs of the big chip that they are made in front of. I am starting to loose hope about getting this to work. Maybe the chip is working fine and I have a bad back up. What would this scenaro look like on a working version of a modded ps2?
