Unless you've got an Asus, Compal, Quanta, or Clevo computer, you probably don't know which company originally built your system, since most brands contract out. But the good news is, if you run Linux, there's a tool that will tell you your system's original manufacturer. Just typeinto your command line program (you'll need to useif you're running Ubuntu) and look for the base board information and chassis information. They should tell you which company REALLY built your computer. Enjoy, and post your computer brand name, model and ODM here! My computer is an Asus, which is its own ODM. But so you've got the format, Asus Z71V - ODM: ASUSTek p.s.: thanks to qhn for finding the link that shows this method!
