I have a 166MHZ/MMX NEC Ready 9733 & I'd like to install a video card but I'm not sure I can. Looking at the manual it looks like the original video card is on the motherboard. I asked someone at NEC tech & he said I could install a video card as it would disable the video card on the motherboard. but I don't trust NEC tech. I do have an open PCI slot. Thanks for your help in advance.
