If u r interested in W98 internals , here is the unveiled mystery of how the source code looks like: /* TOP SECRET Microsoft(c) Project Date : summer 1998 Project name : Windows 98 */ #include "win31.h" #include "win95.h" #include "evenmore.h" #include "oldstuff.h" #include "billrulz.h" #define INSTALL HARD char make_prog_look_big[1600000]; void main() { while (!CRASHED) { display_copyright_message(); display_bill_rulz_message(); do_nothing_loop(); if (first_time_install) { make_50MB_swap(); do_nothing_loop(); totally_screw_up_HPFS_fs(); search_and_destry_rest_of_OS2(); hang_system(); } write_something(anything); display_copyright_message(); do_nothing_loop(); do_some_stuff(); if (still_not_crashed) { display_copyright_message(); do_nothing_loop(); run_windows31(); do_nothing_loop(); do_nothing_loop(); } if (cache_detected) disable_cache(); if (fast_cpu) { set_wait_states(lots); set_mouse(speed,very_slow); set_mouse(action,jumpy); set_mouse(reaction,sometimes); } /* printf("Welcome to Windows 3.1"); */ /* printf("Welcome to Windows 95"); */ printf("Welcome to Windows 98"); if (system_ok) crash(); else system_memory = open("A:\SWP0001.swp",O_CREAT); while(something) { sleep(5); get_user_input(); sleep(5); act_on_user_input(); sleep(5); } create_general_protection_fault(); } }
