Module Name:

    spswitch.h

Abstract:

    Macros & Functions to switch between old and 
    new partitioning engine in textmode.

    NEW_PARTITION_ENGINE forces new partition engine
    code to be used for both MBR and GPT disks.

    GPT_PARTITION_ENGINE forces new partition engine
    code to be used for GPT disks and old partition
    engine code for MBR disks.

    OLD_PARTITION_ENGINE forces the old partition
    engine to used for MBR disks. This option cannot
    handle GPT disks.

    Note : 
    If none of the NEW_PARTITION_ENGINE, 
    OLD_PARTITION_ENGINE or GPT_PARTITION_ENGINE macro
    is defined, then by default NEW_PARTITION_ENGINE is
    used.
