In an instrument family I built, I solved the problem by
including a BOOTP/TFTP bootup client into the instrument.
The service laptop has a BOOTP/TFTP server which is able
to provide the IP address and maybe a download file containing
service code.

DCHP is an extension of BOOTP, so it should not be too
difficult to recode the server in the laptop to respond
to it.

To prevent messup of possible DHCP servers in the customer
network, there is the option of using non-standard UDP port
for the bootup (50067/50068 instead of 67/68).
