items in the Setup Utility: Press <Y> and the <Enter> to install the defaults.
Press <N> and then <Enter> to not install the defaults. The fail-safe defaults
place no great demands on the system and are generally stable. If your system is
not functioning correctly, try installing the fail-safe defaults as a first step in
getting your system working properly again. If you only want to install fail-safe
defaults for a specific option, select and display that option, and then press <F6>.

level of the components, such as the CPU and the memory. You can cause fatal
errors or instability if you install the optimized defaults when your hardware does
not support them. If you only want to install setup defaults for a specific option,
select and display that option, and then press <F7>.
