PXE booting diskless Linux clients?

Question

I currently have a Linux server that uses a combination of DHCP, TFTP, and PXE to boot a series of Linux clients. I would like to replace the Linux machine with a Leopard Server machine, but I don't see how to configure the Leopard DHCP daemon to send the same information.
For reference, here is a section of the Linux dhcpd.conf file:
host goldchannel {
hardware ethernet 00:50:8d:98:f4:8a;
fixed-address 192.168.0.51;
server-name "ISN";
option host-name "goldchannel";
option root-path "/diskless/goldchannel";
if substring (option vendor-class-identifier, 0, 9) = "Etherboot" {
filename "/vmlinuz_arch";
} else if substring (option vendor-class-identifier, 0,9) ="PXEClient" {
filename "/pxelinux.0";
There is also a TFTP server running, but I have seen instructions on how to configure a Leopard server the same way.
Any ideas or pointers would be greatly appreciated.

It looks like you want and need to define extra DHCP option fields.
This is not covered at all in the official Mac OS X Server PDF documentation, but if you open a Terminal window and type *man bootpd* then it will give you some information on this subject. It basically involves manually editing the /etc/bootpd.plist configuration file.
If you look at my previous post here http://discussions.apple.com/click.jspa?searchID=5850185&messageID=6021307 then you will see I am trying to work out how to use this feature as well.
Please let me know by posting a reply here if you get any further than me as I could not get it to work. I have seen a couple of vague comments from other posters suggesting they may have got it working but unfortunately they do not provide details.
Obviously if you do get it working then please post enough of your /etc/bootpd.plist file to be an example.
