17 WinNt emulator of SEC phase. It's really a Posix application, but this is
18 Ok since all the other modules for NT32 are NOT Posix applications.
20 This program processes host environment variables and figures out
21 what the memory layout will be, how may FD's will be loaded and also
22 what the boot mode is.
24 The SEC registers a set of services with the SEC core. gPrivateDispatchTable
25 is a list of PPI's produced by the SEC that are availble for usage in PEI.
27 This code produces 128 K of temporary memory for the PEI stack by opening a
28 host file and mapping it directly to memory addresses.
30 The system.cmd script is used to set host environment variables that drive
31 the configuration opitons of the SEC.
