    TITLE:  Ascentia, 3C689 Token Ring CardWizard

    ISSUE

       CardWizard may misidentify the 3Com card as an IBM Token Ring
       card. If this occurs, the 3Com NIC (Network Interface Card)
       driver will not be able to assign resources to the card.  This
       may produce an error message indicating that IRQ 0 is assigned to
       the card.

    BACKGROUND

       There are four basic sections of PCMCIA support: the card, the
       socket/adapter, the Card Information Structure (CIS), and the
       system software.

       The PCMCIA card holds data vital to working with the system in
       its CIS. The CIS contains information that indicates the
       characteristics of the card and how it should be accessed. This
       information is passed-on to the system.

    ACTION

       To correct the problem, remark out the IBMTOK.CLB entry located
       in the CARDID.INI file in CardWizard. To do so, follow the steps
       listed below:

       1. Use the text editor to open c:\cardwiz\cardid.ini

       2. Scroll down to the line that reads
             CardLib=IBMTOK.CLB
          and place a semicolon (;) at the beginning of the line
          as follows:
             ;CardLib=IBMTOK.CLB

       3. Save the changes and exit.

       4. If this system is being used as a NetWare ODI client,
          modify the NET.CFG as follows:

          Link Driver 3C689
            Primary
            data rate nn

          ; nn is the speed of the Token Ring.

       5. Reboot the system.

    NOTES

       For further information on configuring the Token Ring adapter or
       for further configuring issues, see TB 1551 on AST's On-Line!
