works on early versions of xbox. 1.Open xbox... hook up PC power cable to HardDrive..But still have IDE cable going to Xbox and Xbox Harddrive. 2. Start up Xbox and Pc at the same time........Before PC reconizes drives click "pause/break" 3.Use second IDE channel with no drives on IDE cable. 4.Swap xbox IDE cable with PC IDE (second channel) cable......hit enter......harddrive will not appear on diagnoz 5.use "HDD_Driver" if files are missing dl them from web. Will say found Xbox HardDrive......ect... go to tools make backup...will take couple of minutes. 6.Used "Bert_is_Cheating_on_Ernie_-_The_Pheonix_Project.rar" extracted files.. 7.changed "bert.xtf" to "Xbox Book.xtf" then "snuffleupagus.xtf" to "Xbox.xtf" left......."default.xbe" the on that came with rar file the same. 8.changed "Xbox Book.xtf" the one on the xbox to "Xbox Book.old" "Xbox.xtf" to "Xbox.old" 9.since there is no font folder in early version of the xbox....inserted both *.*xtf files , default.xbe, evox.ini file to "System" Folder using "HDD_Driver" one file at the time..Power off pc take off hardDrive add back to Xbox then power off Xbox...reboot Xbox and it should work. Will get error when running HDD_Driver ...........in my case program close alot so i just ran the program again and again untill I got all the files on Drive. Thats all i did to get it running......to back up games will have to use some sort of file manager app. cuz can't see DVD/D: drive when you ftp to xbox.
