[solved] Variable in boot menu

[NiKiZe]

variables are set by http://ipxe.org/cmd/set and are kept between scripts
--autofree and --replace are only about how the script file itself is handled.

if you have chain boot.ipxe.cfg in your embedded script, after dhcp, it would try to use the default tftp path.
If your http server is on the same server (ip) as your original tftp server than you could use something like:
chain http://${netX/next-server}/boot.ipxe.cfg

You might want to use the config command from the iPXE shell to see what is set
