| | 16 | Abstract:\r |
| | 17 | WinNt emulator of SEC phase. It's really a Win32 application, but this is\r |
| | 18 | Ok since all the other modules for NT32 are NOT Win32 applications.\r |
| | 19 | \r |
| | 20 | This program gets NT32 PCD setting and figures out what the memory layout \r |
| | 21 | will be, how may FD's will be loaded and also what the boot mode is.\r |
| | 22 | \r |
| | 23 | The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r |
| | 24 | is a list of PPI's produced by the SEC that are availble for usage in PEI.\r |
| | 25 | \r |
| | 26 | This code produces 128 K of temporary memory for the PEI stack by directly\r |
| | 27 | allocate memory space with ReadWrite and Execute attribute.\r |
