I have these bios but what do I do with them. All the tutorials ive been in are for other chips. My xbox is not playing dvds, but I have a 160 drive and play orginal games on it. What is 1.2 or m8,m7. What is newer or which one actually works better? How do I flash it. I thought it was hard, it is kind of easy, if there would actually be a tutorial for thais chip. I think if I ever get any oyher chip I wuold have the instrucional tutorials for those. Just how to set it up, and keep it going. Not any info on where to get it. At first I had no clue what a bioi was, now I now all about bios and linux and write programs. BUT how do I apply all ths knowledge to the chip? Ive read how to flash, what am I going to flash? I have flashed one thing. So where does all this come together? Or is my box suppose to say matrix,executer, or sometimes nothing? I know Im doing something or I wouldn't be able to have upgraded my hdd or not play dvds. Can anyone help? read here read there, installed what i read but how does it apply to this chip?
