2 | WinNt emulator of pre-SEC phase. It's really a Win32 application, but this is\r | |
3 | Ok since all the other modules for NT32 are NOT Win32 applications.\r | |
4 | \r | |
5 | This program gets NT32 PCD setting and figures out what the memory layout\r | |
6 | will be, how may FD's will be loaded and also what the boot mode is.\r | |
7 | \r | |
8 | This code produces 128 K of temporary memory for the SEC stack by directly\r | |
9 | allocate memory space with ReadWrite and Execute attribute.\r | |

48 | Routine Description:\r | |
49 | This service is called from Index == 0 until it returns EFI_UNSUPPORTED.\r | |
50 | It allows discontinuous memory regions to be supported by the emulator.\r | |
51 | It uses gSystemMemory[] and gSystemMemoryCount that were created by\r | |
52 | parsing the host environment variable EFI_MEMORY_SIZE.\r | |
53 | The size comes from the varaible and the address comes from the call to\r | |
