The invention consists of a boot loader for a device, comprising an IP stack supporting Internet protocols, and a scripting engine to run a default script. The IP stack includes address discovery service (for example, BOOTP and DHCP), a URI to IP address translator (for example, DNS), and a protocol for file transfer over the Internet (for example, HTTP, FTP and/or TFTP). On start-up of the device, the boot loader runs the default script to initialize the device and verify the integrity of any data and operating systems in memory on the device.
