I think you missed one of the changes (I added an endrow label and a jmp)
or maybe I forgot to post it...
FA> putrow:
FA>         lodsb
FA>         and al, al
FA>         jz nextrow
FA>         stosb
FA> loop putrow
    jmp  endrow ; this is needed otherwise it falls through and makes a mess
FA> nextrow:
FA>      inc di
FA>         loop putrow
    endrow:
FA>
FA>         add di, bp
FA>         pop cx
FA>         loop loophere
