Big thanks to all of you. Now I'm starting to understand how it's working. 
Here is current version of my code:

       jmp         cl_start
cl_id_str:      .string "STRING"
        movw    %cs, %ax
        movw    %ax, %ds
        movw    $0xe000, %ax
        movw    %ax, %es
        movb    $0, %al
        xor         %bx, %bx  # start of segment
        movw    $cl_id_str, %si
        movw    $cl_start, %cx
        subw    %si, %cx
        decw    %cx
        movw    %bx, %di
        repz    cmpsb
        je      cl_compare_done_good
        incw    %bx
        cmpw    $0xffff, %bx  # are we at the end of segment
        je      cl_compare_done
        jmp     cl_compare
       movb $1, %al

And this code won't work as well :(

Unfortunately, I can't start DOS and check, cause there is no video and 
keyboard controller on that PC.

Best reagrds,
