Hi
I have a similar problem, but think my xbox may be a goner. I got an error 13 for a while, and the xbox would intermittently startup, otherwise just crashing with the error. Since i have noticed the change to error 16, it wont start up at all.
I have not changed or removed the dashboard since it worked (about 5 mins before it stopped, and after I had the box open and the chip, an xbit, in and out) , and I am sure the box was not unplugged for more than a few mins...except i get this error, which means it MUST be a clock problem, no? I have tried the D6 bios, with no joy. Also it wont boot up games directly. not good methinks.
I only have a laptop so cant mess with the HDD out of the xbox, and no friends with modded boxes, so I don't know what to do...help please?
cheers
Jan
