hi there
im tryng to convert my retail xbox to debug (xdk 5933)
i use this guide
http://aideluxe.com/index.php?title=AID_Manual_Appendix_F

my question :
can it launch gamea/apps from hdd?
also can it use larger hdd??

I have never followed this tutoriol, but I know it's possible to create a retail / debug setup on a softmodded xbox. It normally boots into retail mode. You ca launch the phoenix bios loader that comes with the ndure softmod in the ndts folder, and have it launch a BFM debug bios. That bios will launch the debug dashboard. As the debug dash has another name as the retail dash, it can be on the C partition together with that retail dash. The method of how things are done is somewhere described in one of the topics here.

regards.
