-Module Name:
-
- SecMain.c
-
-Abstract:
- WinNt emulator of SEC phase. It's really a Posix application, but this is
- Ok since all the other modules for NT32 are NOT Posix applications.
-
- This program processes host environment variables 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 availble for usage in PEI.
-
- This code produces 128 K of temporary memory for the PEI stack by opening a
- host file and mapping it directly to memory addresses.
-
- The system.cmd script is used to set host environment variables that drive
- the configuration opitons of the SEC.
