Configuring the root file system and boot devices

The embedded PC that make the voice recognition can be configured so it boots using the bootp protocol and places the run-time environment into the RAM memory. To do that, the RT-LEAST tool will configure the host machine so it acts as a boot server for the embedded machine. Next, it will adapt the root file system so it works in RAM disk and will patch the kernel so it uses the RAM disk as the root file system. Finally, it will construct a file that contains the run-time environment, i.e.: the kernel plus the root file system. This file will be transferred through the network when the embedded machine boots, thus providing a quickly and hardware independent way of installing the root-time environment to the embedded system, as shown in fig. 7.
