With my BIOS version, I can select the internal, AGP or the PCI as the 
primary card. For capabilities of your BIOS, running dmidecode reveals 
the capabilitied that your BIOS has. For mine, the excerpt from 
dmidecode shows the following. you migh look at the output on your 
computer to check on its capabilities.
