\section{\label{ref:SystemOptions}System}
\subsection{Start Screen}
Set the screen that Rockbox will start in. Selecting
\setting{Resume Playback} will resume playback where it was when the \dap{}
was shut off if there is a playlist to resume and will then end up in the
WPS. Selecting \setting{Previous Screen} will make Rockbox start in the
screen it was when the \dap{} was shut off.
\subsection{Battery}
Options relating to the \opt{archos}{batteries}\nopt{archos}{battery}
in the \dap.
\begin{description}
\item [Battery Capacity: ]This setting can be used to tell Rockbox what
capacity (in mAh) the battery being used has. The default is
\opt{player,recorder}{1500mAh}%
\opt{recorderv2fm}{2200mAh}%
\opt{ondiosp,ondiofm}{1000mAh}%
\opt{h1xx,h300}{1300mAh}%
\opt{ipodmini}{400mAh (1G) or 630mAh (2G)}%
\opt{ipodcolor}{700mAh}%
\opt{ipodnano,ipodvideo,ipod4g,ipod3g}{\fixme{unknown}}%
\opt{x5}{950mAh}%
, which is the capacity value for the standard
\opt{archos}{batteries}\nopt{archos}{battery} shipped with the \dap.
Rockbox uses this value to estimate remaining battery life for the
statusbar and WPS. Changing this setting has no effect whatsoever on
actual battery life. This setting only affects the accuracy of the
battery life estimation as shown on screen.
\opt{ipod}{This value is fairly meaningless in the \playerman{} family at
present, and work is on-going into finding a better way to determine
battery life.}
\opt{ondiosp,ondiofm}{
\item [Battery Type: ]This setting tells Rockbox which type of battery
is currently used in the \dap{}. The two supported battery types are
``Alkaline'' or ``NiMH''.
}
\end{description}
\nopt{ondiosp,ondiofm}{
\subsection{Disk}
Options relating to the hard disk.
\begin{description}
\nopt{ipodnano}{
\item [Disk Spindown: ]Rockbox has a timer that makes it spin down the
hard disk after it is idle for a certain amount of time. This setting
controls the amount of time between the last user activity and the time
that the disk spins down. This idle time is only affected by user
activity, like navigating through the \setting{File Browser}. When the
hard disk spins up to fill the audio buffer, it automatically spins down
afterwards.
}
\opt{SWCODEC}{
\item [Directory Cache: ]Rockbox has the ability to cache the contents of
your drive in RAM. The \setting{Directory Cache} takes a small amount of
memory away from Rockbox that would otherwise be used to buffer music,
but it speeds up navigation in the file browser by eliminating
the slight pause between the time a navigation button is pressed and the
time Rockbox responds. Turning this setting on activates the
directory cache, and turning it off deactivates the directory
cache.
\note{The first time you enable the directory cache,
Rockbox will request a reboot of the \dap{} and upon restarting take a few
minutes to scan the drive. After this, the directory cache will work in the
background.}
}
\end{description}
} % \nopt{ondiosp,ondiofm}
\opt{CONFIG_RTC}{
\subsection{Time and Date}
Time related menu options.
\begin{description}
\item [Set Time/Date: ] Set current time and date.
\item [Time Format: ] Choose 12 or 24 hour clock.
\end{description}
}
\subsection{Idle Poweroff}
Rockbox can be configured to turn off power after the unit has been idle for a
defined number of minutes. The \dap{} is idle when playback is stopped or
paused. It is not idle while the USB or charger is connected, or while
recording. Settings are either \setting{Off} or \setting{1} to \setting{10}
minutes in 1 minute steps. Then \setting{15,30,45} and \setting{60} minutes are
available.
\opt{HAVE_RTC_ALARM}{
\subsection{Wake-Up Alarm}
% TODO this isn't quite right for all targets, I think
This option turns the \dap{} off and then starts it up again at the
specified time. Use \ActionSettingInc{} and \ActionSettingDec{} to adjust
the minutes setting, \ActionAlarmHoursDec{} and \ActionAlarmHoursInc{} to adjust the hours.
\ActionAlarmSet{} confirms the alarm and shuts the \dap{} down, and
\ActionAlarmCancel{} cancels setting an alarm. If the \dap{} is turned on
again before the alarm occurs, the alarm will be cancelled. Using this
option disables the \setting{Sleep Timer}.
\subsection{Alarm Wake up Screen}
This option controls what the \dap{} does when it is woken up by the alarm.
}
\subsection{Limits}
This sub menu relates to limits in the Rockbox operating system.
\begin{description}
\item [Max files in dir browser: ]This setting controls the limit on
the number of files that you can put in any particular directory in the
file browser. You can configure the size to be between 50 and
10,000 files in steps of 50. The default is 400. Higher values will shorten
the music buffer, so you should increase this setting \emph{only} if you have
directories with a large number of files.
\item [Max playlist size: ]This setting controls the maximum size of
a playlist. The playlist size can be between 1,000 and 32,000 files,
in steps of 1,000 (default is 10,000). Higher values will shorten the
music buffer, so you should increase this setting \emph{only} if you
have very large playlists.
\end{description}
\opt{player,recorder,recorderv2fm,gigabeat,ipodvideo,iriver,iaudio,e200}{
\subsection{Car Adapter Mode}
This option turns \setting{On} and \setting{Off} the car ignition
auto stop function.
\begin{description}
\item [Car Adapter Mode: ]When using the \dap{} in a car,
\setting{Car Adapter Mode} automatically stops playback on the \dap{} when
power (i.e. from cigarette lighter power adapter) to the external DC in jack
is turned off. If the \setting{Car Adapter Mode} is set to \setting{On},
Rockbox will pause playback when the external power off condition is
detected. Rockbox will then shutdown the \dap{} after the length of time set
in the \setting{Idle Poweroff} setting (see above).
If power to the DC in jack is turned back on before the \emph{Idle Poweroff}
function has shut the \dap{} off, playback will be resumed 5 seconds after
the power is applied. This delay is to allow for the time while the car
engine is being started.
\end{description}
Once the \dap{} is shut off either manually, or automatically with the
\setting{Idle Poweroff} function, it must be powered up manually to resume
playback.
}
% TODO: this needs to be rewritten in another style, but i really don't know what kind of "line in" this describes... isn't it used for recording?
\opt{player}{
\subsection{Line In} This option activates the line in port on \dap, which is
off by default. This is useful for such applications as:
\begin{itemize}
\item Game boy $\rightarrow$ \dap $\rightarrow$ human
\item laptop $\rightarrow$ \dap $\rightarrow$ human
\item LAN party computer $\rightarrow$ \dap $\rightarrow$ human
\end{itemize}
