/*++

Routine Description:

    This function returns the system ID, which consists of an eight byte
    VendorId and an eight byte ProductId (in this case the ethernet address).

Arguments:

    None.

Return Value:

    Returns a pointer to a buffer containing the system id structure.  This
    structure is initialized on each call to prevent programs from changing
    the value.
