Since you need to differentiate between min and max, I suggest you use something else instead of JNE.

Suppose you want the max to be in AL, and min in DL then:

...
CMP AL,DL
JG notequal  ; max is in AL, nothing should be done
JE equal     ; jump to equal part
XCHG AL,DL   ; since the only possibility left is that AL<DL, they are exchanged
jmp notequal ; now you can jump to notequal
