If you specify one or more BPXPRMxx members on the OMVS= statement in the IEASYSxx member, then the kernel services start up in full function mode when the system is IPLed. To use the full function mode, you need to perform the tasks listed in Table 1.

Before installing the remainder of z/OS, you need to customize SMS, RACF®, and the z/OS UNIX file system.

The setup process is listed in Setting up for full function mode.
