Before I updated my BIOS to the 0602 version, I had been using two graphics cards. To this, I had the BIOS configured under NB Configuration to use both graphics cards; however, ever since I updated the BIOS the NB Configuration option has been gone. As such, I would like to downgrade the BIOS back to the original version (the one from release), or enable both graphics cards with this BIOS. Thanks in advance for any and all help. My motherboard model is the ASUS F2A85-M2.
