##检查根设备是否存在

    sudo dd if=rootimage-0.11 of=/dev/fd1

解决办法：
    
    将第一层主 Makefile 文件中的
    LDFLAGS =-s -x -M 
    修改为 
    LDFLAGS =-m elf_i386 -Ttext 0 
    Image: boot/bootsect boot/setup tools/system tools/build
    tools/build boot/bootsect boot/setup tools/system $(ROOT_DEV) > Image
    sync
    修改为
    Image: boot/bootsect boot/setup tools/system tools/build
    objcopy -O binary -R .note -R .comment tools/system tools/kernel
    tools/build boot/bootsect boot/setup tools/kernel $(ROOT_DEV) > Image
    rm tools/kernel -f
    sync
    将 tools/build.c 文件中的
    	if (((long *) buf)[5] != 0)
    		  die("Non-GCC header of 'system'");
      这段代码注释掉
      //if (((long *) buf)[5] != 0)
      //  die("Non-GCC header of 'system'");
