you bought it. However, under the precondition that you don’t modify Predesktop Area setup in BIOS, HPA is invisible. So it wouldn’t be deleted by mistake. And I had used this method on three T40 laptops: 6BH，19U，G1H, all system hardware drivers would auto install correctly, Access IBM and other IBM preinstalled software are all of Chinese version, and the XP system is also registered. You’d just directly click Windows Update. Really cool, heh….!
