OK, ,I held off talking because I was sure that
someone would mentione this, but why not use the VCI
switch on Romomatic?:
Require an encapsulated Vendor Class Identifier of
"Etherboot" in the DHCP reply Requires DHCP support.
Enabling this makes the boot ROM require a Vendor
Class Identifier of "Etherboot" in the Vendor
Encapsulated Options This can be used to reject
replies from servers other than the one we want to
give out addresses to us, but it will prevent
Etherboot from getting an IP lease until you have
configured DHCPD correctly.'
You can operate two DHCP servers on the same port, but
the Etherbooted computer will only respond to the one
that specifies that it is for Etherboot. No messy
setup. No recompiling.
