17. Flashdisk and Custom ROM
In addition to the traditional memory areas for customer storage in a Windows Mobile device H22
has two additional non-volatile memory areas, the Flashdisk and the Custom ROM areas.
17.1. Flashdisk
The FlashDisk area is a virtual drive dedicated for user data that are not wiped when doing a clean
boot. This is useful for storing customer data. The FlashDisk is accessed from the File manager in
H22.
17.2. Custom ROM
Custom ROM is a hidden partition where customer specific programs and applications are stored.
The reason why this partition must be hidden is to prevent end users from removing or damage the
content of this partition. The correct environment will be restored and setup from this partition after a
boot (clean, cold, or warm) to ensure that the customer environment is setup right. If there is an
Autoexec.exe in the Custom ROM partition this is automatically executed during boot to correctly
configure the device. The Custom ROM area is accessible to the user through a Custom ROM tool
provided by Opticon to Device Administrators.
