Appendix C - Firmware Updates
The design of your WayPoint
tm
PDA permits easy installation of firmware upgrades. A firmware
upgrade can be used to re-install a full copy of the Pocket PC OS and all of the included
applications. The upgrade writes the this data into a 32 Megabyte area that has been provided to
hold the data and does not disturb the 128 Meg ROM area used to store maps and navigation
settings.
Warning - A firmware upgrade performs a hard reset. All user data stored in RAM will be
destroyed. It is highly recommended that the user backup RAM data before applying a ROM
upgrade.
Backup
There are 4 backup strategies that can be employed to preserve user data.
1. ActiveSync can be used to sync PIM data to your PC. Mac or other computer users may
have a similar tool to do this job. Data synced to the main computer can be restored after
the upgrade simply by syncing again. Generally PIM data includes all of your contacts, to-
do lists, and schedules. This list can vary depending on how you set up your sync
application.
2. ActiveSync (and some third party tools) provides the ability to backup all of RAM. If you
have additional data beyond PIM data you can use this method to save your information.
The main problem with this approach is that when the data is restored it could overwrite
some new ROM information. For example, if you load an application that overwrites
some system files and these system files are update in the ROM upgrade the restore could
actually overwrite these updated files with older versions. Third party programs often
allow selective restores which helps prevent this kind of problem.
3. You can manually copy critical data to your computer or to a memory card. This
approach requires your understanding of the files you have added but this may be the
best way. For example, if your added data is stored in My Documents then copying the
