1- Follow E-X-A-C-T-L-Y
this tutorial.
2- Use a recent debug bios as your XDK (i got XDK 5849 and DEBUG Bios 5558. and it works fine. Maybe a too old bios wouldn't work with a more recent XDK so watch out.)
3- Make sure the bios you are using is REALLY a debug bios , AND that it's a 1MB BFM (Bootable from media). Note : Don't ask me where to get all this stuff. If you are ready to install XDK , you should be able to find that yourself. Two days ago i didn't know one single about SDK/XDK and about where this stuff is. And i found it. It's on the net believe me...So don't go telling me "i can't find it". The only hint i'm giving you is :
-Once you found the place where to get it (this place is well known..just think a bit..) the stuff you need is in /XBOX/bios/bootable from media/debug/
4- When you upload the XDK to your xbox , follow the order stated on the 1st post.
QUOTE
5- If you have followed the tutorial exactly like it says, have the good XDK , and uploaded the files correctly, it
WILL work.
6- I would recommend getting XDK 5849 DEC 2003 + 5558_debug bios since that's what i have and it works 100%
