This will work for you
You need a hacked bios I would suggest you use M8plus_16.bin
as this bios is 256k
, the bios will be too small for your modchip
as the bios for your modchip has to be 512k in size
so download evtool
from here http://www.xbox-scene.com/tools/tools.php?page=bios
install it on you PC, and open evtool.exe
in the bottom left of the screen click open and select the M8plus_16.bin bios
wait for it to open
to the left of the open button is a file size option
now click save as and put the file name as bios (Case Sensitive)
check the file size and make sure that it is 512k when saved
Now you have the bios needed
get Eurasia Generic Pro Flash Disc 1.3
The zip file includes eurasia_pro_generic_flash_disc_1_2.iso, burn the iso using nero, by
selecting file then open from the menu and then selecting the above iso
make sure you tick the box to finalize disc before burning.
open the folder bios_disc
and put the bios.bin
you created into this folder
Now open nero again and create a DVD iso disc
copy the four files from bios_disc folder to the dvd you are creating, not the folder
so you should have a disc with just the following files:bios.txt
switch your chip to bank 0 and boot to the cromwell bios screen, place the first disc in
that you burned and push the A button on the controller this will now load, when requested
and the xbox dvd drive opens insert the second disc in, this will flash your new hacked bios
to the chip.
do not turn off the xbox manually during this process as you may damage your modchip
allow the xbox to turn itself off.
when the xbox turns itself off the bios has been flashed
now turn the xbox back on
and your finished.
