+ This PPI is published by a PEIM upon dispatch and provides an execution engine for the\r
+ Framework boot script. This PEIM should be platform neutral and have no specific knowledge of\r
+ platform instructions and other information. The ability to interpret the boot script depends on the\r
+ abundance of other PPIs that are available. For example, if the script requests an SMBus command\r
+ execution, the PEIM looks for a relevant PPI that is available to execute it, rather than executing it\r
+ by issuing the native IA-32 instruction.\r
