In this article about the Hardware Abstraction Layer and SysPrep:

Microsoft makes a number of references to two different subsystems: ACPI and MPS. Both come in uniprocessor and multiprocessor flavors. I understand ACPI means Advanced Configuration and Power Interface).

What does MPS stand for and what is it good at?

    "MPS" in this context actually stands for "MultiProcessor Specification":
    MultiProcessor Specification

    The MPS was developed parallel to APM and PNPBios; ACPI takes care of all of these and moves the responsibility for those formerly BIOS controlled functions to the OS.
    ACPI Component Architecture > Frequently asked questions
    In other words: MPS is outdated.
