Corey, About all you could do is boot into OF by holding down command option O F. Then set the verbose boot-args flag. setenv boot-args -v then do: mac-boot IF you can get anymore info that would do it.

No spinning disk or anything, just the grey screen. The comp has heavily tweaked HW & SW so I'm not bitching, just downgraded to 10.3.3 and everything is fine. Correct me if I'm wrong but the usual boot sequence is: 1. OF loads the first stage bootloader 2. First stage bootloader initializes the computer then loads the kernel 3. The kernel goes off and does it's thing. Now, I'd imagine the problem is occurring either early in stage 3 or late in stage 2. How do I go about debugging these steps? Is there any pointers to some way I could get OF to spit out more info or anything along that lines?
