There are two types of OEM activation schemes. One is called System Locked
activation and is tied to the BIOS. This type of OEM cd's have the BIOS
code and do not generate an activation hardware hash. These systems never
activate over the internet because they are already activated by the
manufacturer by virtue of the BIOS code. A replacement of the same model
motherboard with an identical BIOS is a match with the BIOS code on the cd
and the system remains activated. You could change everything else on the
computer and it would not matter. No activation is required. If the BIOS
does not match, however, a call to the activation center is required.
Your OEM cd is of the other type. Activation does rely on the same hardware
hash scheme retail products do. These are the cd's that sell on eBay.
