GLYPH<SM590000> Linux Secure IPL is available for LPARs running on z15 CPCs 

This new feature checks the software signature before loading the code into the LPAR storage (memory). When Linux Secure IPL is enabled, the signature of the operating system being loaded is compared with the signature from the Linux on Z distribution provider. The load fails if the signatures do not match. 

The feature can be enabled by the selecting the Verify software signature with distributor  option in the image profile load Load task, as shown in Figure 10-4. This feature supports Linux on Z running in an LPAR on a z15 CPC.
