Installing 2.6ce in a ver 1.3 xbox. Soldered pin header, and d0, lan and hd wires. Programmed the chip in my 2.3 programmer. I flashed with 5035 for old mobos along with m8 on the other bank. I have even reflashed with flash 3.01 or even cromwell. All flashes work in the programmer and are verified. When I boot up the xbox with the mod chip enabled, the blue internal and all external lights are working, (bank, hd, lan, etc), but it still boots to M$oft screen. I have even customized a bios that removes flubber and changed the xbox logo, but still no matter what bank I use, mod chip on or off, I still get M$oft booting. It is like I am not grounding D0 to force to go to lpc for bios boot. I never get any fragging. I have tried 2 different mod chips (both 2.6ce) along with changing out the switch banks and other cables. I have even checked for continuity along the D0 wire by going to a point above the diagrammed D0 connection point along its trace, with the corresponding point on the mod chip pc board with the 3 wire cable attached to it. The D0 grey wire is making connection! I would appreciate any suggestions from this point.
