The reset will force a reset, thats true (I am not sure it even goes
through the bios).

Thats mostly false for most machines (at least intels) still alive today
(probably at least somewhere around pentium III 450 and up).  The power
button is usually soft off, where it sends a shutdown message to the
system (sometime needs the option set in the bios), and it sends an apm
or acpi message to the system.

Pressing the button for at least 4-5 seconds will usually force a hard
shutdown.
