Reformatting won't change the options in your BIOS. Are you using Catalyst 8.9?

yes ... ccc 8.9

If I am not mistaken, (and I often am at my advanced age

) I just read something that said that you need to install the drivers with just one card in the system, then install the 2nd card before you will see the crossfire option. I don't know if that needs to be done for an upgrade in drivers. I think it's just for the initial install, or like you are doing, a reformat and re-install of the OS

I 'could' be wrong, but it wouldn't take that much time to give it a try.
