Nervous? I downloaded the new bios THREE times to make sure I didn't make a mistake and download the wrong one.
I downloaded the flash tool twice, again, ensuring I didn't screw up.
I printed the manual and saved the old bios, making sure I had the means to rewrite the incorrect or corrupted bios.
I stood for the entire flashing duration, crossing my fingers and ready to sacrifice a farm animal to ensure it went well.

Jokes aside, everything works perfectly... Windows recognizes the new dual core and I didn't have any problems what so ever.
Thanks for the help everyone, I appreciate it.
