Which one? CPU or BIOS?

The s/n for CPUs are only available on AMD Athlon, Intel P-III and above, and the code can be found at developer.intel.com
The greatest advantage of the CPU s/n is that it is unique for each CPU. It´s not, however, available on most CPUs in the market today (most AMDs, P-I, P-II, etc.. only on P-3 and Athlon).

As of the BIOS s/n, it is not necessarily unique. Two motherboards of the same model that were manufactured by the same company, that have the same BIOS and chipset, WILL have the same serial number. Thus it is not an infalible safety measure. You can download a component that retrieves the BIOS s/n (TASCPUInfo) from my site: www.bhnet.com.br/~simonet

Rakin,

Here's a more accurate URL for the CPU s/n on Intel's site:

http://developer.intel.com/drg/pentiumiii/psnum/index.htm

No. If the CPU is not one of the above (Athlon, P-3 and above), they do not have serial numbers.
