_ DEC-O-LOG for KA47

_ DOL, KA47-F002   SEP 94 

 APPLICABILITY: This "F" coded FCO should be installed in all Microvax 3100   
 Model 30, 40, and 80 which contain part rev. below "M02" or "M03" for FRU    
 54-20654-01 (Model 30 and Model 40) and part rev. below "J02" or "J03" for   
 FRU 54-20652-01 (Model 80).  This FCO incorporates ECO No. 54-20654-TWO007   
 for Model 30 and Model 40 and ECO No. 5420652-TWO006. Please do not make     
 a separate trip to install FCO unless customer is down.  Install the FCO     
 at the next scheduled visit.	          			              

 PROBLEM & SYMPTOM: Previous revision FRU does not see RZ26L and RZ28 drives, 
 if present when booting the system.  This problem is caused by               
 SCSI RESET too short.  This FCO will also correct: 1. MOP SYSID broadcasting 
 alternates MOP3/MOP4 message, 2. SCSI Verify command now with greater than   
 64K block count size, 4. New VMB addresses MOP4 response time issues.        

 SOLUTION: Replace two Firmware ROMS located on FRUs 54-20654-01 and 	      
           54-20652-01.
