    This is a demo and it's main function is:                                 
    1.At real mode,move file "\tc\g\mode.txt" to c_buffer,512Kb ;             
    2.At protect mode,move c_buffer to g_buffer which base_address is 2M,     
and display throungh VRAM.**********************************************
