AST RESEARCH, INC.        TECHNICAL BULLETIN # 1559          08/27/96 
 
 
 
TITLE:  Ascentia P, IBM Token Ring Card, Win95
 
 
SUMMARY 
 
   After adding RAM to the Ascentia P mobile computer, it may not be
   possible to configure an IBM token ring PC Card. 
   
   This issue applies to all Ascentia P systems.    


ISSUE 
 
   After adding RAM to the Ascentia P mobile computer, it may not be 
   possible to configure an IBM Token Ring PC card due to lack of 
   available resources. This may cause Windows 95 to generate an 
   error message that indicates the IBM token ring card is not 
   functioning properly.    

 
BACKGROUND 
 
   The IBM Token Ring PC card requires that two memory addresses be 
   reserved. The default driver included with Windows 95 for the IBM 
   token ring PC card requires that the second memory address range
   be 64KB. After adding memory to the Ascentia P, Windows 95 may 
   report a conflict with PCMCIA Card Services and the card may 
   no longer function.    

 
ACTION 
 
   1. Download version 1.07 or higher of the IBM Token Ring drivers. 
      The current file name is TRDRV107.EXE.
     
      IBM's current ftp site address is as follows:
      (http://www.raleigh.ibm.com/nes/nestoken.htm#trmisc).
   
   2. For installation instructions, follow the directions
      in the README file. For further assistance with the 
      IBM PC card, please contact IBM's Technical Support.    

 
NOTES 
 
   After this driver is installed, Window 95 will only
   require a 16KB address range for the second memory block.
