Hello,

 

I'm trying to figure out how to enable iPXE chainloading as outlined here:

http://ipxe.org/howto/chainloading

 

Here's the logic:

  option client-arch code 93 = unsigned integer 16;
  if option client-arch != 0 {
     filename "ipxe.efi";
  } else {
     filename "undionly.kpxe";
  }
  next-server X.X.X.X;

The short of it is, in ISC based solutions, passing options to ISC like this is usually possible but I can't find it. 

 

If someone could explain to me how it's done or point me to the correct documentation, I would appreciate it.

 

Thanks!

-Bryan

No guarantees, but contact support and ask them for instructions on how to gain access to DHCP expert mode whereby you can essentially manipulate your own dhcpd.conf file.

You can also use DHCP option filters (it's in the admin guide, Chapter 31 Configuring IPv4 DHCP Filters, under the section 'About Option Filters')

 

you can't do if/else logic directly, but you can just create the == and != filters as 2 different rules.

 

I now the answers is a bit RTFM, but the guide will give you the overview of how to set it all up (there are a few steps)
