 SYMPTOM:                                                                       
 IBM PC 700 Series 6875, 6885, 6876 or 6886 systems may display                 
 a "Serious disk error writing to drive C:" message in                          
 Windows 3.1 while connected to a server running Banyan Vines                   
 5.53(0) and attempting to save a file to the local hardfile.                   
                                                                                
 PROBLEM ISOLATION AIDS:                                                        
 Systems running DOS 5.02, and Microsoft Windows 3.1 on a                       
 client system using a SCSI hardfile and connected to a server                  
 running Banyan Vines 5.53(0) are affected.                                     
                                                                                
 The failure occurs when accessing Microsoft Windows applications               
 through the network and saving the modified files to the                       
 local hardfile.                                                                
                                                                                
 FIX:                                                                           
 To eliminate this failure, perform the following steps:                        
 1) Edit the CONFIG.SYS and AUTOEXEC.BAT files to remove or "REM"               
    SMARTDRV.EXE from each file if present.                                     
 2) Start Windows at the client end and access the Control Panel                
    in the Main group.                                                          
 3) Click on the "386 Enhanced" icon.                                           
 4) Click on "Virtual Memory."                                                  
 5) Click on "Change", then check the box labeled "32 Bit Disk                  
    Access."                                                                    
 6) Exit and reboot the system.                                                 
                                                                                
 If the failures persist, continue normal problem determination                 
 to isolate the failing application or FRU.
