Sets the specified environment variables. If -v is specified, more details are shown.ĭisplays the files specified, with a pause at each LINES displayed. If -v is specified, more details are printed.ĭisplays loaded modules. Lists all of the devices from which it may be possible to load modules. This is something that with a second PC (used to download stuff and create boot media) can be repaired with a little work. If that is the case, the Windows OS is still there but you can not boot to it and the PC does not see the OS, as a result. If -l is specified, file sizes will also be shown. First, the boot loader records could have become corrupted. If filename is not qualified, it will be searched under /boot/kernel and /boot/modules.ĭisplays a listing of files in the given path, or the root directory, if the path is not specified. Any arguments after filename are passed to the file. Loads the kernel, kernel module, or file of the type given, with the specified filename. Reads the specified file and interprets it line by line.

If the topic given is index, the list of available topics is displayed. Shows help messages read from /boot/loader.help. This only makes sense if unload is used first, before changing some variables. Goes through the same automatic configuration of modules based on specified variables, most commonly kernel. If kernelname is not qualified, it will be searched under /boot/kernel and /boot/modules. Otherwise, the previously-loaded kernel will be used. Providing a kernel name on the command-line is only applicable after an unload has been issued. Immediately proceeds to boot the kernel, with any specified options or kernel name. It displays a countdown, and the default time span is 10 seconds. Proceeds to boot the kernel if not interrupted within the time span given, in seconds. Loader Built-In Commands lists the most commonly used loader commands.įor a complete discussion of all available commands, refer to loader(8).

If interrupted, the user is presented with a prompt which understands the command set, where the user may adjust variables, unload all modules, load modules, and then finally boot or reboot.

Finally, by default, loader issues a 10 second wait for key presses, and boots the kernel if it is not interrupted.
