I installed a prebuilt NuCore system, but am having trouble with a split image (Here's a post I made about it, if interested: viewtopic.php?f=18&t=1065).
I bought an Ultimarc ArcadeVGA card and just plugged in the video cable to see if anything happened, but as I suspected there's no image, so I'm guessing I need to disable onboard video as a first step. I'm not well versed in this kind of thing, but neither the boot menu nor system menu gave me options on how do do this. Is it a jumper setting? If anyone can step me through the process, or offer any advice on installing the card, I'd appreciate it.
