This is an function to close the S3 boot script table. The function could only | |

1. Closes the specified boot script table | |
2. It allocates a new memory pool to duplicate all the boot scripts in the specified table. | |
Once this function is called, the table maintained by the library will be destroyed | |
after it is copied into the allocated pool. | |

new table to be created by the library. | |

pool that is allocated by this function. | |
