I know that you are waiting for this information on whether this card will work with other boards. Basically during the installation of the card, the K8NXP-SLI is configured to run in NORMAL mode and not SLI mode (since we are only using one card with 2 GPUs). In the windows xp properties, two instances of 6600GT is detected. The graphics driver detects that a SLI card (2 GPU) is installed and prompt you to enable the SLI link. Once that is enabled, you would need to reboot the system and it is done.

After completing the tests, I did try to test the card on two other PCI-E boards, e.g. MSI ATi K8 and EPoX 5EPA+ but it just couldn't POST at all. With the EPoX 5EPA+, the DEBUG leds shows "FF" and it wouldn't continue. I suspect that the graphics card has some form of detection algorithm within the BIOS that detects which board it is used on. Well, that is again my guess and I find that is highly possible as NVIDIA will come knocking on Gigabyte's door as it might affect the sales of SLI boards if the card can be used on any PCI-E board.
