                              Application Note #04
     
     
                     Customizing the MP/M Sign-on Message
                     ------------------------------------
     
     
           The MP/M 1.0 sign-on message can be customized to include an
       ASCII string of your choice which is up to 35 characters.  The
       string must be terminated with an ASCII '$' character.
   
           The following steps can be used to customize the MP/M sign-on
       message:
   
           1.)  Obtain access to CP/M version 1.4 or 2.0.
   
           2.)  Read the XDOS.SPR file into memory using either DDT
       or SID.
   
               A>SID XDOS.SPR
               SID VERS 2.0
               NEXT  PC
               2600 0100
   
           3.)  Store your customized sign-on message beginning at
       location 022AH.  Note that the message should probably begin
       with some <cr> and <lf>'s and that it must be terminate with
       a '$' character.
   
               -S22A
               022A -- 0D
               022B -- 0A
               022C -- "New sign-on message$
               0240 -- .
   
           4.)  Return to the CP/M console command processor (CCP) by
       executing a jump to location zero and then save the updated
       memory image onto a disk file using the CP/M 'SAVE' command.
   
               -G0
   
               A>SAVE 37 XDOS.SPR    ; 37 = 25H
   
           5.)  Run the GENSYS program which will integrate the new
       XDOS.SPR into the MPM.SYS file.
