ASUS P5ND2-SLI bios settings for video card?

My first post yaaaaaay:-)

I've got myself a new system now and the mobo is an asus P5ND2-SLI no it's not the deluxe version. I'm using an evga geforece 7600 GS 256mb pci express/sli video card and I am wondering how do I know if this card is set properly in the bios and also how do I know that it's using sli mode?

Oh yeah also a note to other potential owners of this mobo, update the bios to the latest version if you get some kingston hyperX memory like I did. My board came stock with bios version 0501 and it would not boot normally only in what the bios called "safe mode" so I had to update to the latest bios version which is a beta bios version 0601 I think it was. After that everything went just fine. I'm new to this pci express thing and want to know how to fully benefir from my new card:-) Any help is appreciated thanx.
