- SecMain.c\r
-\r
-Abstract:\r
- WinNt emulator of SEC phase. It's really a Win32 application, but this is\r
- Ok since all the other modules for NT32 are NOT Win32 applications.\r
-\r
- This program processes Windows environment variables and figures out\r
- what the memory layout will be, how may FD's will be loaded and also\r
- what the boot mode is.\r
-\r
- The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r
- is a list of PPI's produced by the SEC that are availble for usage in PEI.\r
-\r
- This code produces 128 K of temporary memory for the PEI stack by opening a\r
- Windows file and mapping it directly to memory addresses.\r
-\r
- The system.cmd script is used to set windows environment variables that drive\r
- the configuration opitons of the SEC.\r
