Xbox Version: v1.6
Use the X2 bios for the chip, latest as you have already discovered is the X2_5035. Remember to use the correct version for you xbpox version: X2_5035_old for non-1.6 consoles X2_5035_16plus for any 1.6 xbox version
remember you will also need to FTP across the ini file that goes with the bios, in orfer for it to look in the correct partition for the installed dashboard etc.
