My first question is, the author of a book I'm reading says the 'initial' kernel is stored in this ROM chip. My question is what does he mean when he uses the word initial? Is there more than one kernel?
Anyway, I know there are a couple ways to do this, but I wan't to monitor the I\O pins on the ROM chip because I will eventually need to monitor the North-South bridge BUS, and I think that this would be a good way to prepare for that. Also I don't have a double-solder iron.
How would I get all these pins hooked up to my FPGA dev board? I was thinking I could get a very small conductive wire, and place it through the test-points which are on all the traces leaving the chip, and solder the fine wire to my larger-wire(which goes to the breadboard and eventually the one of the User FPGA I\O pins). How would I keep this neat and stop a short-circuit with such dense pins? Are there specialized wires for this or something? Will this disrupt the signal at all though provided I am just logging all the relevent pins on the ROM? And can I trust the XBox will access all of this memory? Because if it doesn't I won't get a full dump of the ROM chip.
