Page 4-82 of the PoOPS says: "If CPU power-on reset establishes the configuration, then it sets the architectural mode to one of the following:
- The ESA/390 mode (when neither the ESA/390-compatibility-mode facility nor the CZAM facility is installed) - The ESA/390-compatibility mode (when the ESA/390-compatibility-mode facility is installed) - The z/Architecture architectural mode (when the CZAM facility is installed)" So, when a machine is powered on and has both CZAM and 390-CM, what is the power-on configuration of the CPU?
