I am installing an Xbit 1.5 on an xbox 1.0. I have alinged the D0 pin perfectly, I even feel it fit in the hole, and I can see it with a flashlight in the correct hole. I can tell I am on the other Pogo pins from the indents I have made in the solder. I have installed a couple different versions of iND Bios 5003 not knowing which is correct. I have verified these installs with the software and it all seems good. I go to start the xbox and all it does is turn on turn off turn on turn off squeek and then turn on but flash red and green. I have read the whole board and have tried reflashing it, I have tried sanding it down on the edge slightly near the write protection and I have repositioned it a few times. I am curious about the power input that comes off of the DVD-rom drive, for it is not pictured anywhere, but the xbit 1.5 I have has an extra header which seems to replace the cable from the dvd-rom, and split off to the xbit bios. When I remove the bios all works fine, but with it in, I cannot get a light on the usb header saying it is in use, and I have tried different banks and even Steath mode, and none work with the chip in. Is my chip bad, or is there something I can do to fix this?
