Two posible problems:
1. disable the busmaster:
  recommended by IBM

2. Wrong sequence in mwave in config.sys. This can lead to very very
wait times for the disks. Default it is installed WRONG!


P.S. Uit is dutch for from.

                   instructions for PC Card Director          
                   This document is for the TP 365X/XD, 560/E,
                   760E/ED/EL/ELD/X/XD, and 765 series.       
      - Place $ICPMOS2.SYS above Mwave device drivers in  
        CONFIG.SYS if Mwave device drivers are installed and
        $ICPMOS2.SYS is located below them.

                  Ring under OS/2               

        The following is a basic guideline from the ThinkPad
        of installation and available resources.                       

        1) Follow instructions for Installing Warp                     

        DO NOT INSTALL NETWORK SUPPORT                                 

        DO NOT INSTALL OS/2'S PCMCIA SUPPORT                           


        2) Install PC Card Director for OS/2. DO NOT CONFIGURE THE     

        TOKEN RING CARD IN AUTOCONFIGURATOR                            

        CD - Rom and other drive letter considerations:                

        PC Card director installation by default adds drive letters for

        Flash and SRAM storage device support with no GUI means of     


        This may change your CD ROM drive letter.                      

        On a Warp Connect preloaded image the necessary drives are     

        already REMmed.                                                

        At minimum - REM out                                           

        BASEDEV=PCM2ATA.ADD /S:2 /]DM /NOBEEP :Storage Driver          

        for OS/2 (ATA)                                                 

        Can also REM out                                               

        BASEDEV=OS2PCARD.DMD : Storage Driver for OS/2                 

        DEVICE=x:\THINKPAD\PCMSSDIF.SYS :Storage Driver for            

        OS/2 (Interface)                                               

        DEVICE=x:\THINKPAD\PCM2SRAM.SYS :Storage Driver for            

        OS/2 (SRAM)                                                    

        DEVICE=x:\THINKPAD\FLSH2MTD.SYS :Storage Driver for            

        OS/2 (FLASH MTD)                                               

        DEVICE=x:\THINKPAD\PCM2FLSH.SYS :Storage Driver for            

        OS/2 (FLASH)                                                   

      6) For Machines with MWAVE                                       
        - Adjust COM.SYS                                               

        At the end of the line \OS2\BOOT\COM.SYS add (2,2F8,3)         

        The (2,2f8,3) is necessary to allow OS/2's COM driver to pick
        the DSP modem,                                                 

        which is normally at COM2. If the DSP modem is set to COM1,    

        then use                                                       


        - Move the following line to the end of Config.sys or MWAVE may

        Install software you are using for network support,            

        The following is for installing Warp Connect but may be used
        any platform.                                                  

        - Go to OS/2 System                                            

        - OS/2 Warp Connect Install/Remove                             

        - Warp Connect Selective Install for Networking                

        - Choose Advanced Installation                                 

        - Pick Protocol                                                

        - Configure the IBM PCMCIA Token Ring Adapter                  

        System Interrupt Level = 9                                     

        PCMCIA mode = YES                                              

        * Shared RAM address = D800                                    

        Default Ring Speed = 16 (if applicable)                        

        Shared RAM Size = 16                                           

        * Memory Mapped IO/ROM address = D000                          

        * These memory addresses SHOULD be used on PCI based           

        machines. Other addresses can be used but these have proven
