A Power-on IPL (first row in the table) includes the IPL that occurs automatically

failure. It also includes an IPL started by the timer and a remote IPL started by a
communication line.
A Programmed IPL is an IPL that results from the PWRDWNSYS command with
Restart=Yes*FULL specified.
A Function 3 IPL uses the selected IPL options to load the system. It is started by

from different areas on the load source DASD. IPL type D is from the alternative
load-source device, such as a tape or optical device.
