Coma Console Won't Boot Successfully
Posted 04 August 2005 - 06:43 AM
I've used this page
to try and bring the box out of coma symptoms. All combinations of A18 and 19 to ground still boot to a coma console. (Oddly, only sending A18 to ground made the XBox FRAG, but it could have been due to something else) I also tried the modchip with each of these combinations and still no boot. Are there any suggestions as to what I can try? If not, what is the cheapest way I can go about getting this box to work? Am I going to need a new motherboard? Can I be sure that a 29-wire chip is going to work? Any help is appreciated, because this is about the 10th time that I've reached my wit's end. Thanks in advance!

I don't understand how you can access the cromwell bios on your chip if your experiencing coma symptoms when the chip is enabled. Please clarify...
If you're sure your modchip is installed correctly and you still get coma symptoms, your best bet is to scrap the mobo and get a new one; there is something else wrong with it besides the onboard bios. A 29wire chip would, most likely, give the same results as your LPC chip.

I get coma symptoms with the chip when it's switched to the first bank, which has had any number of X2 bioses. When I have it switched to the second bank, which is Cromwell, it loads Cromwell without a problem. I can flash the first bank or do anything else that Cromwell can do, but that's it. No matter what BIOS I put on bank 1, I get coma symptoms. The only progress I get is that when I put one of the newest X2 bioses on, I get the "Loading X2 Config Live" message before it goes blank.
Is there any way of having an idea what else could be bad on the motherboard? I'd love to see if that component can be replaced, or if I've missed a broken trace or something. I really don't know how this mod went wrong, as I barely had any problems with it.

I think I'll make it my test/experiment board. Not good for much else.

Your best bet is ebay, the best deals are buying broken xboxes that have DDE's and stuff. I just bought one from ebay a few days ago, it was a coma'ed 1.4. Put in a chip and it has been working great.
