Discs like that, could be used on more than one model of computer. The software is activated by the presence of "SLIC" info in the Lenovo BIOS. The idea is, if I try to install that disc on my Asus motherboard, then the OS shouldn't activate. Whereas, if a Lenovo BIOS is present on the motherboard, the OS should be activated immediately. Whether that disc works on everything, may depend on drivers. If the BIOS, IDE interfaces are set to Compatible or Enhanced, then the default disk drivers may work immediately. And perhaps you'd need to add video drivers, to make the installation complete (if the computer is different than the one it was intended for). If you were using a newer computer, with the interface jammed into AHCI mode, then maybe it wouldn't boot after installation. I've even heard of a few discs, older ones, where they work with any motherboard (when really, they shouldn't). Undoubtedly, someone out there knows all the ins and outs of those things, where they'll work and won't work. If they're Lenovo branded, then try them on a Lenovo computer. See the "SLIC" section here for more details. SLIC is for "branded OEM" discs.
