Dealing with d0:problem: its hard to get that big pogo to connect solidly with d0 becuase d0 is really small.
solution: enlarge d0.
how? it's easy.
1) Call local auto supply store. Ask for the conductive paint used to repair rear window defroster wires.
2) Go there.
3) Buy it for about $8-10.
4) Go home.
4.5)if you didn't already, take out the IDE cable from the mobo. It's worth it so you can see stuff better.
5) Screw your xbit into place, making sure that all the pogo pins snap into their holes on the LPC port. Wiggle it around and make sure its where it wants to be.
6) Find the pogo pin that is closest to d0, and using a pencil or fine marker, mark the approximate location of the d0 pogo on the mobo (this step is not neccessary if the pogo pin is on d0 already)
7) Remove the xbit and set aside.
Gently scrape d0 with something small and sharp. You dont need to get all the plastic, just remove enough so that some shiny, scratched metal is showing. While you're scraping stuff, you might as well scrape the rings that make up the LPC port. Just insert a knife tip into the hole and spin it. The places that get shiny are the only ones where the pogos will make contact anyway. As long as your preparing stuff, might as well clean or scrape the pogos on the chip.
9) Get some bright light on your exposed mobo. Now, using something really thin (I used a little jeweler's screwdriver) paint some paint onto d0.
10) Start by putting a little drop right down into the d0's ring.
11) Now, making sure not to get paint on any other little rings, apply a little bit of paint to the board. Draw a little line of paint over to and beyond the point where the pogo that was intended to contact d0 touched down on the board.
12) inspect your work. If you got paint where you didn't want it, dont panic. To remove unwanted paint, simply let it dry just until the glossiness dissapears (20 seconds?) and then scrape it away. (A long wedge cut from a disused credit card works well) Be careful if using a metal scraper, if you scrape away to coating and expose the traces, shorts could occur.
13) about 2 minutes from the first application of paint, reapply (It'll be easier to control where the paint goes this time, it'll kinda stick to the dried paint).
14) let it dry. I decided that the best way to dry the chip was to blow some hot dry air across the paint while gently raising its surface temperature, so I reassembled the xbox and played some games for about half an hour. Maybe you should wait longer, like 24 hours or whatever, but I didn't.
15) Reinstall your xbit. Put your yellow and black wires in first, and get them all threaded to the exterior, and get of the slack taken out of the wires.
16) Position the xbit and spacer. Thread the mounting screw into the screw thingy the absolute minimun distance to not come out.
17) Line up the XBit so that all the Pogos are above the LPC as they should be and that the d0 pogo is above or touching the paint. Avoid scraping the pogo across the paint from side to side, as it is possible for the paint to flake off. With the xbit in what looks like a good position, press it down with your hand, compressing the pogo pins. Gently wiggle the chip and feel as all the pogos snap into place. When it is in what looks like a good place, while still holding it down, tighten the screw. Place the chip where you want it and then use the screw to hold it there. Dont use the screw to move the chip.
18) Get your eyes down low and see that d0 is making good contact with the paint. If you want make damn sure the connection is made, you can apply a little more paint which will stick to the pogo and to the paint trace. When you see the paint form that nice fillet between the paint and the metal, you know contact is made. Might as well be soldered, you say to yourself.
19) put xbox back together.
20) Use XBTOOL to change your bios .bin so that the power LED is changed color. Also, I like to change to colors of the xbox logo. Make it something drastically different. Be aware that the power led will be green immediately following power on, and then will turn red about the time the xbox logo is displayed.
21) Flash your xbit. Be sure to put 256k bios' in 256k slots. I used m7 and placed it in slot 5 in memory configuration 5.
If it works, you're done. If it doesn't work, the contact between the pin and d0 was not your (only) problem.
