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 |
