This looks like some good stuff here Michael. I have only memorized certain 0x_____ mean boot from certain places. It seems like you know quite a bit more into it. I was trying to understand what you wrote but I don't get it. Are you saying after the--> 0x like if you had 0x0001 it would = boot field- I don't understand can you explain a little more for the slower ones out here?
