that is built into all SUSE distributions. This entails modifying a file named

boot CD.
This method is a little less intrusive than modifying the

There are three types of driver update operations that can be performed:
Install the kernel modules or hardware drivers

The example in this section takes the program "tree" that is not currently available in the imaging
distribution and installs it at boot time.
The driver update mechanism seeks the
