dw 0,0

code segment
start :mov ax, data
mov ds, ax
mov bx,0
jmp word ptr [bx+1]
code ends
end start

assume cs : code
data segment
    dd 12345678H
data ends

code segment
    start :mov ax, data
    mov ds, ax
    mov bx, 0

    mov ds:[bx],bx
    mov ds:[bx+2],cs

    jmp dword ptr ds: [0]
code ends
end start

2000:1000 BE 00 06 00 00 00 

则此时，CPU执行指令:

mov ax, 2000H
mov es, ax
jmp dword ptr es: [1000H]

后，(CS)=00BE，(IP)=0006
