Thanks for all the tips, but I did it, and I don't know why it worked. Basically here's what I did tonight:
Cleaned and resoldered AGAIN.
Nothing. Damn.
So, I tried booting up without either drive hooked up, power or otherwise. And then, WTF!! it booted to the logo screen! Ok, so in a fit a joy, I hooked up the dvd from my box with the original hd from this box, loaded my 007 memcard, flashed, reboot with new bios with no hitch. Again, WTF. So, I hook up the original DVD drive, and now all of a sudden it works fine. So I put in the new HD, etc etc, and all is well.
In conclusion, I have decided to blame spongebob squarepants. When I finally got the drive to work, I opened it up and there was a spongebob disc in it. So I politely removed the disc, and decided that old SBSP must have been screwing with me.
Well, I showed his a$$.
REPREZENT DEEZ NUTZ, b17ch!!!
