    TITLE:  PCMCIA, 3Com 3C589B, Ascentia P and J

    ISSUE

       The Ascentia P or J systems may not recognize the 3Com 3C589B PC
       card. The system may hang when "Net Start" is run in the
       AUTOEXEC.BAT when using Windows 3.1x with NDIS 2 Drivers.

    BACKGROUND

       The PCMCIA 3Com 3C589B card needs to be configured with the same
       settings as referred to in the PROTOCOL.INI file that is located
       in the Windows directory . The card may also need to be
       configured using the configuration utility supplied.

       When using the default installation of a 3Com PCMCIA card, the
       interrupt setting and the I/O address setting are not added to
       the PROTOCOL.INI file.

    ACTION

       To resolve the issue in the Ascentia P, edit the PROTOCOL.INI
       file. Before attempting to edit this file it is recommended that
       a backup copy of the file be made. After doing so, edit the file
       as follows:

          [ELPC3]
          DriverName=ELPC3$
          ioaddress=0x300
          interrupt=0x3

       To resolve the issue in the Ascentia J, edit the PROTOCOL.INI
       file as follows:

          [ELPC3]
          DriverName=ELPC3$
          ioaddress=0x300
          interrupt=11

    NOTES

       The top settings are the default settings of the 3Com board. To
       change these settings, the user can run the Install program from
       the diskette supplied with the 3C589 card. Change the
       configuration to reflect the changes in the PROTOCOL.INI file.
       The latest 3C589 configuration utility can be downloaded from the
       3COM's web site at http://www.3com.com or ftp.3com.com. The file
       name is 3C589N.EXE.
