Nvidia 7900 SLi problem/question

[ferrari24]

I have an SLi-ready Mobo and the 7900 GT KO in my computer. I just purchased the 7900GS and put that in my second PCI-E slot and connected the two cards with my SLi cable. I can not find any options to run them in SLi mode, why is this?

Other PC specs attached to my user profile.

Have you installed all the proper motherboard drivers? Is the second card detected by the OS (operating system) or in the bios?

Well, on startup, there is not display to the monitor on the second graphics card, but once Windows boots up there is.

Yeah, maybe it's not showing up in the BIOS. I'll check that.
