Mr_Biggle_sworth Posted April 6, 2023 Report Share Posted April 6, 2023 Hi all, dug out my old xbox original which was last booted up around 15 years or more ago to find it not working as I left it. It's an xbox original with a Xenium modchip in it (one of the ones that you push in and then have a wire that sits in one of the solder holes - picture attached). As an additional problem I can't remember a thing about how it is set up or where the wire should be or what the extension cable (which currently not connected) even does and can't find any of my old notes on it. So any/ all help very much appreciated as to how to proceed on this. Basically, when you switch it on, it currently flashes green three times then goes to a green, red, green, red repeating colour change. If I move the wire out of the hole that it was located in, then it boots into normal mode and I can set the time etc. As soon as I put the wire back to where it was, then it does the not booting and colour sequence as above. Pic attached of modchip. If more information is helpful on something specific please let me know!. Quote Link to comment Share on other sites More sharing options...
KaosEngineer Posted April 7, 2023 Report Share Posted April 7, 2023 The spring wire from the solderless adapter goes in the D0 via for your motherboard version.

KaosEngineer Posted April 7, 2023 Report Share Posted April 7, 2023 To solve the FRAG problem, I suggest reseating the solderless adapter. It may not be making a good connection to all of the pins of the LPC debug port to load the BIOS from the modchip. 1 Quote Link to comment Share on other sites More sharing options...
Bowlsnapper Posted April 7, 2023 Report Share Posted April 7, 2023 To avoid future problems, if you are comfortable soldering, just seat the modchip onto the board using a pin header and solder the d0 wire. Solderless connections are going to be unreliable over long periods of time due to oxidation and corrosion, etc... 1 Quote Link to comment Share on other sites More sharing options...
Mr_Biggle_sworth Posted April 7, 2023 Author Report Share Posted April 7, 2023 (edited) Thanks for the replies. So having checked D0 was in the right place. (I used to be comfortable soldering, but it's been 20 years so don't feel comfortable any more in response to Bowlsnapper). It was to do with the seating of the adapter. Basically, if I press down in the bottom right hand corner lightly, it seems to engage properly and load up ok. Otherwise it does the same light pattern as below. What are my options to try and get this seated better without having to hold it down (I can't see anything that is physically blocking it from seating down)?

KaosEngineer Posted April 7, 2023 Report Share Posted April 7, 2023 Add some solder to the pads on the far end that are not making a good connection. Doing so will raise the contact point so the pogo pin can make a better connection to them. 1 Quote Link to comment Share on other sites More sharing options...
