A few weeks ago I bought an xbox with a smart xx lt opx chip with no bios. I was too optimistic and thought it would be easy to find the right bios and instructions if I just searched for it. Needless to say it wasn't that easy and after a couple of days of desperate searching for a solution I gave up. I once found a bios that I thought was the right one but then discouvered that my banks were too small. For the bios I had found I needed 512 kb and the banks on my xbox only had room for 256 kb.
So what I wonder is if some kind soul could tell me where I can find the correct bios and give me a good description on how to install it.
I don't think I will ever get my xbox working correctly otherwise.
