Shutdown computer in MS-DOS using ACPI

Question

I have MS-DOS 6.22 running on a Pentium based computer (motherboard supports ACPI), and would like to know if there was an assembly language routine I could use to shut down the computer, or is it a little harder than that (i.e. motherboard specific)?
