I 3704/3705 Control Proqram CAftOn 0 corresponds to -0 following the subchannel address on
the ADDRESS operand of the tIRE macro in Stage 1 of the EP
system qeneration. (0 may have been coded or defaulted on the
LINE macro; you must specify it on the CAKOD option.) CAftOn 1 corresponds to -1 following the subchannel address on
the operand of the LIRE macro in Stage 1 of the EP
system qeneration. EXECUTION OF THE SAVENCP PROGRA" The DIAGNOSE X'50' instruction invokes the CP module DKKSRC to: • Interpret the parameter list (CCPARM) built by SAVENCP. • Check the parameter specifications against the RAKERCP macro for the 3104/3705 control proqram. • Write tbe paqe-format image of
appropriate CP-owned volume.
the control proqram onto the
The parameter list for the DIAGNOSE instruction must start on a boundary. When tbe DIAGNOSE X'50' instruction is executed, the module DKKSNC searches the D"KSNT module for a NAftENCP macro of the same ncpname as
the one in the CCPARft parameter list. The values specified in the
parameter list are compared to tbose specified in the NA!ENCP macro. If
any parameters conflict, an error message is displayed at the terminal.
If no error conditions are detected, DKKSNC starts to transfer the
control proqram image from CMS virtual storage to the CP-owned volume
specified in tbe NAMENCP macro. Successful completion of this process
completes the qeneration of a 3704/3705 control program for VK/370 use. Step 10. Load the 3704/3705 Control Program
The 3704/3705 control proqram is automatically loaded each time the V"/370 system is loaded, if the CPNAKE operand was specified on the RDEVICE macro when VM/370 was generated and if the 3704/3705 is online.
If the CPNAftE operand was not coded, you must issue the CP NETWORK LOAD command line to load a 3704/3705 control program into the 3704/3705 Communications Controllers' storage.
THE NETWORK LOAD COMMAND LINE Use the NETWORK LOAD command to initiate the loading of an EP control
proqram into a 3704/3705 Communications Controller. The format of the NETWOPK LOAD command line is: f" , NE'rwork LOAD raddr ncpname L ________________________________________________________________________________ 312 IBM VM/370 Planning and System Generation Guide

"IPL Required" state at the time the is issued, the message:
DMKNET461R CTLR raddr IPL NOT REQUIRED; ENTER "YES" TO CONTINUE: appears at the terminal. If the reply to the message is other than
"yes", the command terminates without loading the 3704/3705. Otherwise, the loader bootstrap routines are written to the 3704/3705 and loading
starts. 'K/370 does not execute the "bring-up" test routines as a part
of the load process. If these tests are to be made, they must be run
from a virtual machine with the 3704/3705 dedicated. When the load of the centrol program image is complete, the command
processor verifies that the 3704/3705 configuration described by the
contrel program can be serviced by the VM/370 CP control blocks in
storage. SPECIAL CONSIDERATIONS FOR LOADING THE EP 3704/3705 CONTROL PROGRAM If a 3704/3705 Emulation Program is automatically reloaded after a 3704/3705 failure, the system may loop after the restart. The message
