Those that have fitted a CoolRunner to an Xbox Slim will be no stranger to the fact that it can take a great deal of trial and error to get the optimized boot times down to less than 5 seconds.
The main issue is the CPU_RST wire which has to be up to 50cm long and then coiled underneath the motherboard. In many cases the positioning of the coil is a factor due to signal interference. Then you have to try different lengths, 40cm,
We believe we have developed a simple yet elegant solution for this problem.
Using the process of serpentining, we have designed a QSB PCB for the 360 slim that fits neatly into place, giving you an optimized solution enabling you to select several different lengths without having to cut any wires and eliminates any guess work and possible signal interference issues.
Since the CoolRunner has been out in the wild, we have collected data from hundreds of testers and implemented the optimum lengths that were reported as giving the most consistently good results.
Simply cut the blue CPU_RST wire to 8cm and then you can select from 50cm, 47cm, 41cm, 38cn, 35cm, 32cm & 29cm.
We have also included all the POST points for the developers out there who wish to use that part of NANDPRO 3 that was implemented by Tiros.
To give you an idea of how the serpentining is used, I've adjusted some values in photoshop so you can get a better idea
