2. In the CONFIG.SYS file on OS/2 Installation diskette 1, ensure that the 
   following two statements are present:
   
         BASEDEV=CMD640X.ADD 
         BASEDEV=CMDATAPI.FLT

3. Add the switch /CH2:0 to the end of the BASEDEV=CMD640X.ADD 
   statement, as follows:

         BASEDEV=CMD640X.ADD /CH2:0
