Adding Devices to the System

At boot time, the system does a self-test and checks for all devices that are attached to it. After you add a new device to the system, use boot -r to activate dynamic reconfiguration of the kernel. A reconfiguration script is run to load all the device drivers listed in the module's directories and to create the corresponding hardware nodes. See the kernel(1M) man page for more information.

You can also use boot -a to interactively add drivers or modules to the system, but if you do, you will be asked to provide other boot parameters, including what to boot and where the root file system is.

Paths to the system files and kernel modules are stored in /etc/system. When the system boots, it reads the information in /etc/system to determine which modules to load. You can specify a different path by using the MODDIR syntax of the system(4) file or by using boot -a.

For more information about boot(1m) or about adding devices and drivers, see System Administration Guide.
