12 | Module Name:\r | |
13 | \r | |
14 | SecMain.c\r | |
15 | \r | |
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 processes Windows environment variables and figures out\r | |
21 | what the memory layout will be, how may FD's will be loaded and also\r | |
22 | what the boot mode is.\r | |
23 | \r | |
24 | The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r | |
25 | is a list of PPI's produced by the SEC that are availble for usage in PEI.\r | |
26 | \r | |
27 | This code produces 128 K of temporary memory for the PEI stack by opening a\r | |
28 | Windows file and mapping it directly to memory addresses.\r | |
29 | \r | |
30 | The system.cmd script is used to set windows environment variables that drive\r | |
31 | the configuration opitons of the SEC.\r | |
