ACPI is not actually firmware -- ACPI doesn't actually DO anything like
firmware does. Firmware is sort of like "permanent software" (executable code
stored usually in non-volatile RAM or ROM), while
Hello Bret,
My overall point was that you can't turn on the PSU (to boot the computer) with
ACPI because ACPI only starts working after the computer (main part of the
motherboard) already has power and has booted an OS. You can't turn the PSU on
with software (like ACPI) that requires the

No, Bret, *you* are missing the point.
This is not about the _motherboard_ getting power. It is about the
Well, I may as well throw my two cents in here. :)
On computers using a standard ATX power supply, pin #9 on the connector
provides power to the motherboard at all times as long as the PSU itself has AC
wall power power coming in.
Modern motherboards use this "Standby" power to run small

You all are missing the point. As soon as the motherboard gets power, it
starts booting. That is how it has always worked.
The problem is how to get the appropriate

The short answer is no, that is not possible.
The long answer is that what you're talking about really has nothing to do with
ACPI and rather

This feature was nonstandard across various BIOS implementations, so it is
highly likely that if the BIOS does not support it via its built-in interface
(the "Press to enter SETUP" prompt) it is probably entirely unavailable.
Just to be sure, I checked the [CMOS Memory Map
Hello experts here!
I am forwarding you a question abou ACPI interface. Although I am the author
of ACPITOOL I am not able to answer it.
Thanks
