                ASCENTIA 900N HAYES PCMCIA MODEM NOT FUNCTIONING IN SLOT 1

    PROBLEM:        The Hayes PCMCIA modem does not support VLSI in slot 1 of the
                    Ascentia 900N system.

    CAUSE:          The original drivers provided with the Hayes modem did not
                    support VLSI implementation for slot 1.

    SOLUTION:       The new release of the Hayes enabler supports the VLSI
                    implementation of slot 0 and slot 1.  It is available on the
                    Hayes BBS (404)446-6336 8N1.  The file name is "ENABLR21.EXE"
                    (dated 8-24-94) and it is a self extracting zip file.

                    You can see the VLSI name when you install it:  To install the
                    driver, download the file from the Hayes BBS.

                    1. Copy the file to a blank formatted diskette.
                    2. From the DOS prompt, execute the program ENABLR21.EXE.
                    3. Take out (REM out) the card and socket services in your
                       CONFIG.SYS.
                    4. Run the INSTALL.EXE.  Disable the option to install under
                       Windows.
                       Install point enabler only.  Select the slot you want to
                       use for the modem.
                    5. Wait for the installer to tell you to reboot (3-4 times).
                    6. At the end of the installation, the modem should work in
                       slot 1.

                    NOTE:  To use a different slot, a line that the installation
                    program added to your AUTOEXEC.BAT must be modified -
                    modmactiv /c2 /sB /i3 /pD000.  The switch /sB means slot B
                    (slot 1).  It can be changed to /sA for slot 0 or vice versa.
                    Moving the PCMCIA card from one slot to another does not make
                    it auto sense.  The README.TXT file has better descriptions of
                    the whole process.
