really?!?

what about windows instrumentation?
what about apic/acpi standard interfaces?
what about user-land/mode driver modules?

None of these methods (which are standardized) permit setting BIOS options.
They are mostly read-only, or edit the Plug-and-Play database.

ps
suggesting somebody to reverse the bios is one of the boldest things
i've heard in the last 15 years (you should copyright it and publish
it! it really made my day here! :-)

Dear All,

Is it possible to change BIOS using a C/C++ programm? For example I
must activate Hyperthreading in BIOS for all machine. It would be
nice to have a script or program, which will do it automatically.

For all practical purposes, the answer to your question is no,
there's no way to do that.

With sufficient work (which would probably entail
reverse-engineering parts of the BIOS), I'm sure it could be done,
but the solution would almost certainly be hardware and BIOS
specific. There's simply no standard for how BIOS settings are
stored or manipulated.
