PROBLEM & SYMPTOM: 
While installing or configuring EISA/ISA devices on       
Digital 2100 Server customers or engineers may experience the following      
problems:                                                                    
   - Failure to run the ECU                                                   
                                                                              
   - No timer interrupts reported under the console                           
                                                                              
   - Corruption of data in the NVRAM which will result in loss of environment 
     variables and failure to run the ECU                                     
                                                                              
   - Addition of new EISA/ISA options to systems may cause the system to hang 
     during the power-up script                                              
                                                                             
     While O/S running, " SHOW TIME" and "SET TIME" commands may give wrong  
     results.  These problems may occur in the standard I/O board B2110-AA or
     54-23146-01 with CS Revision at or below "F02".                        


SOLUTION: 
Install B2110-AA part revision "H02" or higher.		    

QUICK CHECK: 
Look for B2110-AA part revision "H02" or higher in backplane 
slot 0 or at console prompt type "show fru" and return. ChecK 
the HW Rev. under I/O (B2110-AA) option.
