按照实验文档：

修改gdbinit为

set architecture i8086
target remote :1234

然后

make debug

但显示却不是

0xffff0: ljmp $0xf000,$0xe05b

而是

The target architecture is assumed to be i8086
warning: No executable has been specified and target does not support
determining executable automatically.  Try using the "file" command.
0x0000fff0 in ?? ()
Breakpoint 1 at 0xffff0
=> 0xfff0:      add    %al,(%bx,%si)

为什么会这样呢？
