  1. TITLE: 941114 Configuring the NEC 260 IDE cdrom under OS2 Warp.     
  2.                                                                     
  3. DESCRIPTION OF SYMPTOMS:                                            
  4.     A NEC 260 IDE cdrom is not being recognized by OS2 Warp.        
  5.                                                                     
  6. SUMMARY OF RESOLUTION:                                              
  7.     Make sure the proper drivers are loading in config.sys and      
  8.     that the necessary files are located in the proper directories. 
  9.                                                                     
  10. DETAILS OF RESOLUTION:                                              
  11.     If you have already installed OS2 Warp, and are trying to get   
  12.                the cdrom recognized, follow these instructions:     
  13.                                                                     
  14.      1. Go to the OS2 Selective Install utility. From the list of   
  15.         cdrom's, select the NEC 260. Click OK. At the System        
  16.         Configuration window, click OK again. At the Setup and      
  17.         Installation window, select the Install button.              
  18.                                                                      
  19.      2. Insert the OS2 diskette when prompted.                       
  20.                                                                      
  21.      3. Edit the OS2 config.sys in the root directory of the hard    
  22.         drive. Find the line:                                        
  23.                                                                      
  24.                           BASEDEV=IBM1S506.ADD                       
  25.                                                                      
  26.         Add switches to this line so that it reads:                  
  27.                                                                      
  28.                           BASEDEV=IBM1S506.ADD /A:x /U:y /ATAPI      
  29.                                                                      
  30.         The /A switch refers to the adapter number that the cdrom    
  31.         is attached to. The /U option references the unit or device  
  32.         number on a particular adapter. The /ATAPI parameter         
  33.         enables ATA Packet Interface protocol for the NEC 260. If the
  34.         cdrom is attached to the second IDE port or adapter in a     
  35.         system and is the only device on the adapter, you would enter
  36.                                                                          
  37.                           BASEDEV=IBM1S506.ADD /A:1 /U:0 /ATAPI          
  38.                                                                          
  39.         in the config.sys. If the cdrom is configured as a slave, or sec 
  40.         device, you would specify /U:1. The config.sys should also conta 
  41.         the statements:                                                  
  42.                                                                          
  43.                            BASEDEV=IBMIDECD.FLT                          
  44.                            DEVICE=C:\OS2\BOOT\OS2CDROM.DMD               
  45.                            IFS=C:\OS2\BOOT\CDFS.IFS                      
  46.                                                                          
  47.          These should have been added by the Selective Install program.  
  48.                                                                          
  49.          If you are trying to install Warp from the NEC 260 cdrom,       
  50.          simply configure the BASEDEV=IBM1S506.ADD  line per above.      
  51.          If you find that OS2 still does not recognize the cdrom,        
  52.          make sure that the /A and /U parameters are specified           
  53.                                                                          
  54.
