Thanks for the reply and great info! So, I do have A22 BIOS on it. Wondering if it's possible to downgrade it to A21? I got the box with A02 on it and could not install Snow Leopard until I updated it to A22. Now I wish I would have read this post before starting.
OK, just tried and answered my own question, I reverted to A21 and trying it again. It failed to update BIOS on the frist try, just had to do it a second time and it took.
