I am working on someone's HP 510w tower. They had two cd drives in it and wanted me to take out the primary and add a CD-RW in there. I did that and it wouldn't start up, on closer inspection, I figured it had to be a jumper problem. I disconnect the second CD Rom (which by the was was an after market also, and not installed correctly because it wasn't identified in device manager) once i pulled the plug on that one, this one started right up. I need to know the jumper setting for the secondary drive. I know that sounds easy, but I'm not sure with HP
