The system startup will be interrupted as soon as the device probes have been completed, and you will be prompted for a shell. Always choose sh: some other shells, notably bash, get confused in single user mode. Only the root file system will be accessible, and it will be mounted read-only. The reason for this is that the file system may be damaged and require repair before you can write to it. For example, npx0 on motherboard npx0: INT 16 interface (end of the probes (high intensity display)) Enter pathname of shell or RETURN for sh: (hit RETURN) erase ^H, kill ^U, intr ^C # mount -u / (mount root read/write) # passwd (Change your password here) # ^D (enter control-D to continue startup) Greg
