H131259 - Auto 16/4 Token Ring Adapter Fails after Flash Update              
                                                                                
                                                                                
                                                                                
 SYMPTOM:                                                                       
 IBM PC 300 Series 6576 and 6586 systems with an IBM Auto 16/4                  
 ISA Token Ring Adapter installed may fail to connect to the LAN                
 after updating the Flash BIOS level from LPJT56A to LPJT59A.

 None                                                                           
                                                                                
 FIX:                                                                           
 When installing Flash BIOS level LPJT59A, REMOVE the Auto 16/4                 
 ISA Token Ring Adapter from the system.                                        
                                                                                
 The Flash update process is reordering the IRQ choices for the                 
 adapter.  The original IRQ setting for the Token Ring adapter                  
 is no longer valid.                                                            
                                                                                
 If the system has been updated WITH the Auto 16/4 Token Ring                   
 adapter installed, and exhibiting the failing symptom, perform                 
 the following steps in sequence to correct the failure.                        
                                                                                
 1) Access the systems Setup Utility by pressing F1 during the                  
    memory count.                                                               
 2) Select the option to "Load Default Settings."                               
 3) Disable Serial Port B (COM 2).                                              
 4) Disable ROM Shadowing at C8000h-CFFFFh in the Advanced Setup                
    menu.                                                                       
 5) If there are any other adapters in the system, ensure that                  
    the IRQ's for those adapters are set as NOT AVAILABLE in the                
    ISA Legacy Resources menu.                                                  
 6) Reboot the system with the LANAID diskette inserted in                      
    Drive A:.  Press F5 to bypass the CONFIG.SYS and AUTOEXEC.BAT               
    files.                                                                      
 7) Type LANAIDC /PNP=Y and press ENTER.  This will set the                     
     adapter for Plug n Play mode.                                              
 8) Remove the LANAID diskette and reboot the system.                           
 9) Access the Setup Utility by pressing F1 during the memory                   
    count.                                                                      
10) Reenable Serial Port B (COM 2) and the C8000h-CFFFFh range                  
    in the ROM Shadowing menu.  Reset any IRQ's that were set                   
    for NOT AVAILABLE in step #5 to AVAILABLE.                                  
                                                                                
 The Auto 16/4 Token Ring adapter should function normally.  If                 
 the adapter continues to fail, verify that the steps above were                
 followed correctly and continue normal problem determination                   
 to isolate the failing FRU.                                                    
                                                                                
 NOTE - The steps above may need to be modified depending on the                
        adapters co-existing with the IBM Auto 16/4 Token Ring                  
        adapter.  Memory address ranges and IRQ's for other                     
        adapters may need to remain NOT AVAILABLE or DISABLED to                
        allow proper operation.  Consult the Users Guide for the                
        adapter for additional information.
