//
// File Name:
//      makebt32.c
//
// Description:
//      This program copies the images of the 4 Windows NT setup disks to
//      floppy disk so the user can boot their system with them.
//
//      All characters and strings are wide (UNICODE).  This file needs to be
//      compiled with UNICODE and _UNICODE defined.
//
// Assumptions:
//      This program will only run on NT 3.51 or later.  This is a result of
//      the CreateFile function call.  It is not available on DOS, Windows 3.1
//      or Windows 9x.
//
//      The floppy disk images are in the current dir and named CDBOOT1.IMG,
//      CDBOOT2.IMG, CDBOOT3.IMG and CDBOOT4.IMG.
//
//      Please note that there are a lot of places where I call exit() without
//      freeing memory for strings I have allocated.  This version of the
//      program only runs on NT so when the process exits it frees all its
//      memory so it is not a concern that I may not call free() on some memory.
