The internal ports can just be disabled in the bios. The risers aren't hard to find, either, but we would need to know the pinout (check the manual). <div class="gmail_quote">On Sep 30, 2012 11:18 PM, "Chick Tower" <<a href="mailto:c.e.tower@gmail.com">c.e.tower@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I wanted to use both a serial and a parallel port on my desktop PC, but it's new enough that it has neither. I found several PCI cards on Newegg that have serial and parallel ports. However, in my motherboard manual it appears there are internal plugs for cables on the motherboard for one of each port. Would a PCI card interfere with the motherboard's ports? Is there any reason it wouldn't work with Linux? Are there cables that can connect to the motherboard and some external ports that are simply mounted on something like those metal covers for the PCI slots? Does anyone know of a cheap, local source for these devices?
