    14 <p>This page describes how to configure how ECom behaves during system boot.

    15 It is intended for Symbian Developers optimising or troubleshooting the boot

    16 process for a phone. </p>

    17 <p>The Symbian platform has a Staged Start-up Architecture, driven

    18 by the Application Framework's System Starter component, which provides a

    19 consistent and customisable method of starting components at device boot.

    20 The architecture divides the start-up process into a number of <i>states</i>,

    21 which allows components to perform only those start-up actions which are necessary

    22 to the state. This allows the start-up sequence to be optimised, so that functionality

    23 that is immediately important to the user starts first. Components that use

    24 this architecture to manage their start-up are called Start-up State Aware

    25 (SSA). </p>

    26 <p>By default, ECom is SSA. It loads registration files for plug-ins on read-only

    27 internal drives first, while start-up is in the "Critical" state. Registration

    28 files for plug-ins on other drives (i.e. installed third-party plug-ins) are

    29 loaded later, when start-up moves to the "Non-critical" state. </p>

    30 <p>ECom's SSA behaviour can be disabled, in which case all plug-in registration

    31 files on all drives are loaded when ECom is started. To disable the SSA behaviour,

    32 place a file called <filepath>EComSrvr.ini</filepath> in either of the directories <filepath>C:\private\10009D8F</filepath> or <filepath>Z:\private\10009D8F</filepath>. The file can have any contents or be empty: its existence alone disables

    33 the SSA behaviour. To reenable SSA, remove <filepath>EComSrvr.ini</filepath> from

    34 both directories. </p>
