I have isc-dhcp-server running on my router, and it currently supplies info needed for booting diskless devices (mythtv boxes, etc).
The actual booting takes place on my server though, and I want the server to supply the dhcp options rather than the router, but still want the router to supply the address etc. This is so I am only editing this stuff in one place, and can script the configuration depending on how I want to boot (boot direct to iscsi with an iscsi filename, or chain via pxelinux where required, etc).
Technically, I think you can do this with IPv6 by allowing the client devices to obtain their addresses from router advertisements while supplying other options via DHCPv6. Unfortunately, this own't help you, as the firmware of your devices supports IPv4 only.
