boot from a large iso file

[sleepybrown]

I hate to threadjack. Please let me know if I should start a new thread. I'm trying to do the same but under a different application. I'm using FOG on Ubuntu and want to load a Hiren Boot DVD that is over 2gb. The issue is that I run out of memory on the client PC.

Code:

:MENU
menu
item --gap -- ---------------- iPXE boot menu ----------------
item hiren Hiren Boot CD 15.2
item shell ipxe shell
item return return to previous menu
choose --default return --timeout 5000 target && goto ${target}
:hiren
initrd http://${fog-ip}/fog/iso/Hiren/hbcd-15.2-Restored-V1.1-dvd-proteus.iso
chain memdisk iso raw ||
goto MENU
:shell
shell ||
goto MENU
:return
chain http://${fog-ip}/${fog-webroot}/service/ipxe/boot.php?mac=${net0/mac} ||
prompt
goto MENU
autoboot
