I am not able to see my boot up BIOS, only when I get to windows do I see video start.
I am running in SLI with one monitor - DVI
Any suggestions?  Or is this a known problem?

    You need to post all your system specs .....
     
    Also try it w/ just 1 videocard in first
    & make sure your Mainboard BIOS is the latest version. ...

    I have the same problem.  I foud out that the post screen and all that stuff like to show up on one video card and when it finally boots up into windows, it goes into the other.  I have 2 monitors and I have it both connected to the bottom video card.  I do that for heat issues when running games.  When i need to reboot and go into bios, I just remove one monitor cable and plug it into the the top video card.    Hope this helps you

    Yup, that is exactly what happens to me.  One video card will show the post screen and not windows...and the other card will show windows and not the post screens.  so there is no fix?  Others have this same issue?

    As far as I know, there is not.  It is a pain in the arse but I only have to use the bios every now and then.  You can just switch both connectors to the other card and call it a day.  I have to have mine connected to the bottom card because of heat issues.  For some reason it runs cooler when I use the bottom card instead of the top card.

    Thank you - Does this apply to other SLI configurations or only the 780?  This is a real bug that EVGA needs to address - How can I submit this?  Thanks again-

    Think this has more to do with the MB than the video card.  I would guess that sli is not supported for video in bios.  The bios sees a gpu in the primary slot and outputs video to it by default.  If a display or multiple displays are only plugged into the second card no video would result until getting into windows.
