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 | |
952261d5 LG |
20 | This program gets NT32 PCD setting and figures out what the memory layout \r |
21 | will be, how may FD's will be loaded and also what the boot mode is.\r | |
2e19fd0f | 22 | \r |
23 | The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r | |
24 | is a list of PPI's produced by the SEC that are availble for usage in PEI.\r | |
25 | \r | |
952261d5 LG |
26 | This code produces 128 K of temporary memory for the PEI stack by directly\r |
27 | allocate memory space with ReadWrite and Execute attribute.\r | |
