Ok, here's the deal. I have a modded xbox (xecuter 2) with a flashed bios and evox installed. I don't know what version bios is installed (both evox and avalaunch say unknown). Anyways, the bios is really old, and the EvoX is the older version too. So right now, I have the Slayers 2.6 CD. My question is, should I flash the bios using the Slayers CD? Is there a better/safer way to flash? Also, what are the banks? I've heard people talk about bank 1 and bank 2, but not sure what it means (something to do with modchip?) Please help me out! Thanks!!!
