Inside Security (insert)

[draugadrottinn]

With some trial and error, I've been able to get Knoppix 7.2 to boot with the following PXE menu (APPEND is one line...):
***************************************************************
label 3
menu label ^3) Knoppix 7.2
KERNEL http://xxx.xxx.xxx.4/knoppix-tftpboot/linux
APPEND nfsdir=xxx.xxx.xxx.4:/var/lib/tftpboot/knoppix-tftpboot/cdrom nodhcp lang= ramdisk_size=100000 init=/etc/init apm=power-off loglevel=1 initrd=http://xxx.xxx.xxx.4/knoppix-tftpboot/miniroot.gz libata.force=noncq tz=localtime lang=en apm=power-off nomce libata.force=noncq hpsa.hpsa_allow_any=1 loglevel=1 noswap nofstab nopcmcia nofirewire BOOT_IMAGE=knoppix
***************************************************************
I've loop mounted the iso image to /var/lib/tftpboot/knoppix-tftpboot/cdrom
The linux and miniroot.gz (and the remaining filesystem in knoppix-tftpboot) were from "knoppix-terminalserver" script form the live boot environment, which I copied over.

I'm still trying to get it to iPXE boot - but I've been consistently failing.

So, my question is...What is the iPXE equivalent to my PXE menu that works here? If I can get Knoppix to function with iPXE, then I can get Insert to function with iPXE as they are almost identical. (Why am I still using Insert you may ask - well, I am very familiar with it, it's tools, and how to manipulate it for various tasks - mainly data recovery; and I feel that familiarity is one of the best tools.)
