An extract from bug #949655 at bugs.debian.org:
I finally found on iPXE website[1] a link to detailed examples, including one[2] to boot pxelinux. It works perfectly with di-netboot-assistant:
#!ipxe dhcp set 210:string tftp://my_server/d-i/n-a/ chain ${210:string}pxelinux.0For those who did not know (like me
), 210 is a standard DHCP option called "path prefix"[3].
