Sorry... been working a ton lately. Board is the AAHD2-HY.
I'm not sure if I'm just not searching correctly or what, but I can't find any information on BIOS upgrades or pin settings to disable the chip, or anything on setting up crossfire with an integrated GPU. If anyone has any experience or insight, it'd be super helpful. I'm about an hour away from taking my power supply out and boxing it back up and returning the damn thing... but I'd rather not pay a 15% restocking fee, especially if it's something I can do, but just can't figure out.
