Hi there,
Webconverger can work work off the Internet and out of contact of
https://config.webconverger.com/ with a configuration like:
homepage=about:blank
noconfig
Which you could either pass on the syslinux command line or by the
configuration panel initially. If you run the install version and set
the configuration from the panel, it will be cached and from that point
on, it won't connect with
https://config.webconverger.com/ again.
You might want this sort of configuration if you have some intranet, but
otherwise I do not recommend it. Since:
a) You cannot update your configuration again until you re-install
b) If you're not online, you can't upgrade.
I hope that help! Kind regards,
