The /ELAN qualifier has two values: enable and disable. With
    /ELAN=ENABLE along with the keyword STARTUP, the LAN emulation
    is loaded when LANACP starts. With /ELAN=DISABLE, the same
    parameters used with ENABLE can be invoked.

    The /ELAN qualifier's syntax is as follows:

    DEFINE DEVICE/ELAN =(parent=parent device,
                         name="ELAN NAME to join",
                         size=1516
                         type=CSMACD
                         Enable,
                         Disable,
                         description = "description string,")
