My Team DMS X-B.I.T. modchip installation was a little bumpy, but in the end it worked out. See, the X-Bit is primarily sold as a solderless chip (although you can solder it into place if you want), and installation is supposed to be as simple as opening your Xbox, connecting a couple cables, and screwing the modchip into place so its pins make contact with just the right spots on the motherboard. I followed the instructions on the DMS web site, but when I tried to start up my Xbox it just flashed red and green lights at me. The issue I had was that while the two primary rows of pins on the chip fit very neatly into actual contact holes in the Xbox motherboard, the “xD0″ pin, as it’s called, only presses down on a PCB trace (those light green lines that are all over a motherboard). I didn’t realize how important it was for this to make contact, so after first installing the chip the Xbox wouldn’t boot unless I flipped the switch to bypass the custom BIOS — thus using Microsoft’s regular Xbox BIOS. At first I thought the BIOS hadn’t flashed correctly, so I kept trying different banks for the BIOS. In desperation, and by this time thinking I had a faulty modchip, I took the Xbox apart again, removed the modchip, and wiped down all the contact points on the motherboard. After reinstalling it, it worked great!
