Please HELP me windows freezes

[harry-parate]

I have flashed my ms28 with xtreme5.2a using a via-6421a now I am trying to put it in enable800 mode like the textbook says (page 72) burned iso to dl and put it in the 360 and when i boot up my computer it freezes or the computer will boot up but the 360 flashes two red lights

i updated my drivers for my via6421 and now windows doesnt freeze when booting up and it recognizes my 360 drive as a cd drive but before i can do much the two red lights start flashing and the drive is no longer recognized under window so i still need a little help
