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 | |
