Nor do I have the manual to hand, but tasm 3.1 seems to accept an ORG 
directive happily.  I'd try something like this

        ORG     0
ZERO    equ     $
        ORG     0F000h
   ; your code here
        ....
� � � � mov � � dl, HERE ANF 0FFh       ; = 61h
� � � � mov � � dh, HERE SHR 8          ; = F1h
        ....
serv220: � � � � � � � � � � � � � � � � 
HERE    equ     ($ - ZERO)              ; = 0F161H
        ....
        
You could try something like that...
