WinNt emulator of SEC phase. It's really a Win32 application, but this is\r
Ok since all the other modules for NT32 are NOT Win32 applications.\r
\r
- This program processes Windows environment variables and figures out\r
- what the memory layout will be, how may FD's will be loaded and also\r
- what the boot mode is.\r
+ This program gets NT32 PCD setting and figures out what the memory layout \r
+ will be, how may FD's will be loaded and also what the boot mode is.\r
\r
The SEC registers a set of services with the SEC core. gPrivateDispatchTable\r
is a list of PPI's produced by the SEC that are availble for usage in PEI.\r
\r
- This code produces 128 K of temporary memory for the PEI stack by opening a\r
- Windows file and mapping it directly to memory addresses.\r
-\r
- The system.cmd script is used to set windows environment variables that drive\r
- the configuration opitons of the SEC.\r
+ This code produces 128 K of temporary memory for the PEI stack by directly\r
+ allocate memory space with ReadWrite and Execute attribute.\r
