I'm having trouble figuring out where to putting this thing onto my motherboard. Can't find anything that fits into it. I did try jamming it in and then it fit just perfect but didn't work. Any one know where it goes?
To quickly sum it up, the problem is the board doesn't support that connector.
You have a socket for a 1394a connector on the motherboard (which is probably what you're plugging the serial connector into) but that's for a Firewire port not a serial port.
Without knowing anything about the rest of your system it'd be impossible to give a recommendation. I'd need to know your CPU model, whether you have SATA or IDE hard drives, what kind of ram you have, etc
Most new motherboards do not have any onboard serial ports. If you need serial ports I'd recommend a PCI Express x1 to serial port card. I got a $30 one from Rosewill that works nicely on Windows 7 and Ubuntu Linux and it has 2 ports. I don't think Newegg has it anymore though.
