                    PREMIUM EXEC SUSPEND/RESUME AND PROTECTED MODE

    The Premium Exec 386SX Suspend/Resume feature will not function when running
    software that requires Protected Mode operation.  This includes applications,
    such as Windows 3.0 and extended memory managers (i.e., QEMM and ASTEMM).

    This problem is caused by the 386SX microprocessor's requirement for
    applications or memory managers using extended memory to run in protected mode
    only.  All 386SX "notebook" type computers, equipped with a Suspend/Resume
    feature, exhibit this anomaly and to date, there are no known resolutions.
