CPU Serial Number

[Leonardo Custodio]

Has anyone worked or have any hints on how to get the Processor Serial
Number in C?
I've read the material within the Intel(C) webpage, but it only gives me the
CPU ID table, no information on where (memory) to get it.

Thank you,

This is not a manufacturer independent notion. Not all cpus have unique
serial numbers. The closest thing you can get to a manufacturer
independent unique identifier is the ethernet interface MAC address,
if any. Every MAC address is supposed to be unique, but not every machine
has an ethernet interface, and some machines have more than one.

STIDP instruction, but it is privileged.

Oh, for intel CPU's, you should have said so in the first place. Yes,
there is an instruction to get it there, too, on newer CPU's.

Or in MVS+ one can examine the PCCA.

Ask in comp.lang.asm.x86

Wrong group.
