I recently got 2 xbox projects to undertake. Both are 1.6 xboxs with 1.1 spiderchips. I had done a previous pinheader/solder install on my own 1.1 xbox and decided to give both these xboxs pinheader installs as well. I completed one of the xboxs with ease-- rebuilt the LPC, soldered the E wire to the d0 on the back, etc.. booted just fine into the cromwell bios and it's now functional. However, the other xbox turned out to be a different story. I followed the same procedure as before on the 2nd xbox, except this xbox frags. I noticed the spiderchip LED blinks as well (indicating that the d0 wire is fine?). This leaves me to believe that there is a broken connection somewhere on the board itself. Rather than buy a $60 motherboard off ebay, i'm hoping to repair it myself with a multimeter and jumper wire to where ever the problem lies. I should mention that this 1.6 board had a bunch of lacquer filled holes-- does anyone think it's in my best interest to desolder the wires and attempt to clear the holes-- or should I consider this mobo nixed?

Problem solved. Got out the multimeter... was a broken/burnt trace. Ran a jumper and the box boots fine.

Good job , you the first person on here to solve your own problem !
