<concept id="GUID-01F1F488-8E95-56B0-818E-6096CAE4C50C" xml:lang="en"><title>Architecture</title><shortdesc>his topic describes the architecture of the Base Starter program, <filepath>e32strt.exe</filepath>.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>

<p>The Base Starter is started by the File Server, <filepath>EFILE.EXE</filepath>,

near the end of the boot process. </p>

<p> <filepath> EFILE.EXE</filepath> initialises generic file services. <filepath>e32strt.exe</filepath> performs

handset specific initialisation. The Base Starter completes the initialisation

of the file server, and then creates the system starter process. The system

starter process is the next process in the chain of processes responsible

for starting all the major Symbian OS services. The following diagram shows

the relative position of the Base Starter in the start-up sequence. </p>
