You didn't mention an operating system, but I'm pretty sure
`/etc/p6update -nv` works on both OpenServer and UnixWare.  Processor
serial numbers are only reported if they're present, which is true only
on Pentium III CPUs.  Earlier CPUs didn't have PSNs, and Intel dropped
them in the P4 after so many people complained about supposed privacy
concerns.

`/etc/hw -v -r cpu` will report on the presence of the processor serial
number feature.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
