-Module Name:
-
- SecMain.c
-
-Abstract:
- WinNt emulator of SEC phase. It's really a Win32 application, but this is
- Ok since all the other modules for NT32 are NOT Win32 applications.
-
- This program gets NT32 PCD setting and figures out what the memory layout
- will be, how may FD's will be loaded and also what the boot mode is.
-
- The SEC registers a set of services with the SEC core. gPrivateDispatchTable
- is a list of PPI's produced by the SEC that are available for usage in PEI.
-
- This code produces 128 K of temporary memory for the PEI stack by directly
- allocate memory space with ReadWrite and Execute attribute.
