+                       Suppressing the MP/M Loader Display
+                       -----------------------------------
+     
+     
+           When the MP/M 1.0 loader reads in and relocates the MPM.SYS
+       file, a load map is diplayed on console #0.  In some applications
+       it may be desirable to suppress this display.
+   
+           The MP/M loader display can be suppressed as follows:
+   
+           1.)  Edit the LDRBIOS.ASM file, replacing the console output
+       code with a RET instruction.
+   
+           ;Loader BIOS jump vector
+   
+                   ...
+                   jmp     conout
+                   ...
+   
+           conout:
+                   ret
+   
+           2.)  Follow the steps provided in Application Note #01 to
+       integrate the new LDRBIOS into the MPMLDR.COM file.
+   
+           3.)  Follow the steps provided in Application Note #02 to
+       update the cold start loader with the new MPMLDR.COM file.
