system IPL time. If an automatic load is not desired,
omit this operan d.
Note: Failure to code the CPNAME operand on the RDEVICE
macro for the 3704/3705 base address causes VM/370 to
mark the device "not operational" at IPL time. The
cluster on that 3704/3705 is therefore unusable.

following coding guidelines on subsequent RDEVICE macros: • Omit the CPTYPE, CPNAME, and MODEL operands. • Specify the ADAPTER as IBM1, TELE2, or BSCA, as appropriate.
For ADAPTER=IBM 1 (or TELE2), the SETADDR operand must also be
specified, exactly as if the device were a 2702 or 2703. If you use the (cuu,nn) form of the ADDRESS operand to generate
multiple RDEVBLOKs and also specify the CPNAME and ADAPTER=TYPE1 operands on the RDEVICE macro, the additional RDEVBLOKs are generated as
ADAPTER=IBM1 and SETADDR=4.
