Here's some mail I wrote about this last year which I think addresses  
the issue.   Executive summary: you don't need to hack source to do  
that - just hack the dhcpd.conf file.   I'd appreciate it if you  
could add this to the bug and then close it so that this doesn't get  
asked again.   Extra credit: put it in a HOWTO (this is extra credit  
because you need more information than just how to configure the DHCP  
server, and I don't know that information, so can't provide it to you).

BTW, the bug that might stop you (which is alluded to below) is that  
it may be the case that the DHCP server doesn't correctly decode  
incoming options.   If that's the case, you'd have to write the if  
statement a little differently - if (option-221 == ...) { ... }  
instead of what's written below.

I noticed a thread about netbooting Macs, and thought I would forward
some mail I sent to the NetBSD/macppc mailing list a little while ago
on the topic.   There's a fellow who's done some patches to make the
server support Mac-specific options.   These patches aren't necessary,
but you might find it instructive to look at his web page anyway.
I've written up a set of config file directives that accomplish the
same purpose as his patches, which you can use instead of the patches.
   I have not actually used or verified these directives, so you might
have to tweak them to get them working, but I think they are
substantially correct.
