What is Extended ROM?
            It is well known that ROM has the core OS files of Windows Mobile, which is non writable at end End user level. It can only be upgraded by the official releases. Apart from ROM, all(most) pocket pc devices have Extended ROM with installation files customized to the manufacturer. It contains typical cab files that gives dialer skins, network settings, patches and some other softwares which are selected by the manufacturers. Its usually arond 18-20mb, non writable and hidden too. Some softwares like Total commander for pocket pc can make them visible. But making it read/writable is not officially allowed. It can be done with some tweaks unique to every device type. We have given some Extended ROM unlocking tools which were made by other developers.
 
Note: Unlocking the Extended ROM of your pocket pc expires warranty and its a risky process too! You agree to take your own precautions on following this guide. Though we try to offer possible support in our forums.

Have you noticed after Hard-reset, your pocket pc prompts something like "Your device will be customized in 3secs"? Following this gets installed those Ext.ROM applications based on configuration files. If you perform a soft reset to your pocket pc before the 3secs run out, you can skip those instalation files and also you extended ROM would have become visible further. This method could save a lot of space in your pocket pc by not installing unwanted cabs. You can later get into the extended rom folder with your normal file manager and install necessary cabs alone. Actually i never install any of them. Except for some cabs which says patch and speed dial application. Also skipping photo id caller which takes around 2.5mb, as i dont require it or may use photo contacts pro installed to my memory card.
