implement ACPI (very very hard) or use the power switch (very easy)

flip the switch on the computer? that will shut it off
seriously, if you want to turn it off in software, without using the BIOS calls, you must either write a separate driver for each MB, or implement ACPI

Why not just reverse the going to Pmode method, that's what i do.
Here's demo to do this:

NOTE: This demo goes to realmode to swich vesa mode, but it could just as well shutdown.
