Can anyone explain to me briefly how to use ipxe to launch the proxmox iso installer.

I have tried the automated installation docs and built a ISO with the answer.toml, but I just cant seem to boot proxmox8 or proxmox9 via the initrd/linux26

What I have done:
* Used the official docs to make a valid answer.toml Automated Install (Official Docs)
* Built a bootable iso from: proxmox-auto-install-assistant prepare-iso ./proxmox-ve_8.4-1.iso --fetch-from iso --answer-file ./answer.toml
* Optionally attempted to use morph027 github tool for creating bootable initrd/linux to create a initrd/linux26 that I can boot with ipxe: bash pve-iso-2-pxe.sh ../proxmox-ve_8.4-1-auto-from-iso.iso
* Added it to my ipxe menu below, but it would either boot and never find /dev/sr0, or just not even boot and return to the ipxe menu, can anyone help?

My Ipxe menu:

Code:
#!ipxe
kernel http://192.168.0.181/FILES/pxeboot/linux26 vga=791 video=vesafb:ywrap,mtrr ramdisk_size=16777216 rw quiet initrd=initrd splash=verbose proxdebug
initrd http://192.168.0.181/FILES/pxeboot/initrd
boot

I will keep looking at this but if anyone has a defined process for basically adding the proxmox9 or proxmox8 iso to boot from ipxe, please help... :(
