    TITLE:  Ascentia P70/P80, MS-DOS, Token Ring

    ISSUE

       An IBM Token Ring PC card may not function properly or at all
       when installed in an Ascentia P70/P80 system with MS-DOS 6.22.

       This issue affects all Ascentia P70 and P80 systems with the
       following part numbers: 503252 and 503302.

    BACKGROUND

       N/A

    ACTION

       To correct this problem, observe the following points:

       1. The EMM386 line in CONFIG.SYS should include the
          exclusion X=CC00-DFFF and resemble the following
          example:

             DEVICE=C:\DOS\EMM386.EXE NOEMS X=CC00-DFFF

       2. The PCM.INI file, located in the Phoenix subdirectory
          (C:\PCM4\PROGRAM), should resemble the following
          example:

       ; PCM.INI - Initialization File for PCM Version 4
