How to set up automatic updates and configurations
For a thin client running ThinOS to successfully access INI files and update itself from a server, you must set up the server with the
correct folder structure where the INI files and other update files are located, direct the thin client to the server, and then reboot or start
the thin client
Once DHCP and servers are configured and available, the thin client checks (at each boot up) to see whether or not any updates are
available on a predefined server DHCP Option
#161 specifies the server URL, DHCP Option #162 specifies the root path to the server. If
updates are available, the updates are automatically installed.
Using DHCP options
This table contains the DHCP options available for use.
