  64. Following are a number of notes about usage, and                                
  65. about potential compatibility problems with the                                 
  66. microcode levels on various adapters and devices.                               
  67.                                                                                 
  68.  Adapter:  All Adaptec adapters                                                 
  69.  Note:     SCSI hard disks must be configured as SCSI target                    
  70.            ID 0 or 1 to be able to start up from that hard                      
  71.            disk.                                                                
  72.                                                                                 
  73.  Drive:    IBM 0661 - 320MB SCSI                                                
  74.  Note:     Adapter BIOS will not recognize the drive as                         
  75.            Target 0 or 1 (Drives 80, 81).  For OS/2 2.0, the                    
  76.            drive can be used as a non-startup drive.                            
  77.                                                                                 
  78.  Adapter:  Adaptec AHA-174x                                                     
  79.  Drive:    IBM WDS-3180 - 80MB SCSI, IBM WDS-3160                               
  80.            - 160MB SCSI                                                         
  81.  Note:     Adapter will not recognize these drives when                         
  82.            configured in 'STANDARD MODE' (AHA-154x                              
  83.            emulation).  Instead, the AHA-174x adapter should                    
  84.            be configured in 'ENHANCED MODE'. This mode is                       
  85.            supported by the OS/2 2.0 drivers, and the                           
  86.            problem does not occur when the adapter is                           
  87.            operating in enhanced mode.

  94.            adapter is controlling the startup diskette.                         
  95.  Note:     Will produce the message, "Disk read error has                       
  96.            occurred" when you attempt to start the

  123.          is VCN:1-02 and works with OS/2 v2.0.                                  
  124.  Resolution:                                                                    
  125.          Upgrade to current BIOS level of VCN:1-02.  Also,                      
  126.          Always IN 2000 SCSI Host Adapters may require an                       
  127.          EPROM upgrade from Always for $20 to operate with

  171.  Problem:                                                                       
  172.          Microcode lower than 2.6 will cause numerous

  182. Some SCSI card have jumper pins which can be set to either                      
  183. Synchronous or Asynchronous mode. There have been noted                         
  184. problems such as no icons appearing or slow hard disk                           
  185. performance. This can be attributed to the SCSI card and                        
  186. hard disk not being set to the same asynch or synch                             
  187. settings. Either way, they must match. Be sure these are set                    
  188. properly.                                                                       
  189.                                                                                 
  190. The early versions of the IBM 16-bit SCSI adapters may                          
  191. experience problems and report erroneously that the device                      
  192. is not functioning.  This can be corrected by replacing the                     
  193. SCSI card with a card with updated microcode.
