MC32N0. Applications stored in the Application folder are retained even when the MC32N0 is cold booted, just as

the Sample Applications program is retained in memory.

There are two device drivers included in the Windows CE image to assist developers in configuring the MC32N0

following a cold boot: RegMerge and CopyFiles.

RegMerge.dll

RegMerge.dll is a built-in driver that allows registry edits to be made to the Windows CE registry. Regmerge.dll runs

very early in the boot process and looks for registry files (.reg files) in certain Flash File System folders during a cold

boot. It then merges the registry changes into the system registry located in RAM.

Since the registry is re-created on every cold boot from the default ROM image, the RegMerge driver is necessary to

make registry modifications persistent over cold boots.

RegMerge is configured to look in the root of two specific folders for .reg files in the following order:

• \Platform

• \Application

Regmerge continues to look for .reg files in these folders until all folders are checked. This allows folders later in the

list to override folders earlier in the list. This way, it is possible to override Registry changes made by the Platforms

partitions folders. Take care when using Regmerge to make registry changes.

Note: Regmerge only merges the .reg files on cold boots. The merge process is skipped during a warm

boot.

Making modifications to registry values for drivers loaded before RegMerge is not recommended. However, these

values may require modification during software development. Since these early loading drivers read these keys

before RegMerge gets a chance to change them, the MC32N0 must be cold booted. The warm boot does not re-

initialize the registry and the early loading driver reads the new registry values.

Do not use Regmerge to modify built-in driver registry values, or merge the same registry value to two files in the

same folder, as the results are undefined.

CopyFiles

Windows CE expects certain files to be in the Windows folder, residing in volatile storage. Windows CE maintains

the System Registry in volatile storage. CopyFiles copies files from one folder to another on a cold boot. Files can be

copied from a non-volatile partition (Application or Platform) to the Windows or other volatile partition during a cold

boot. During a cold boot CopyFiles looks for files with a .CPY extension in the root of the Platform and Application

FFS partitions (Platform first and then Application). These files are text files containing the source and destination for

the desired files to be copied separated by “>”.

Files are copied to the Windows folder from the Flash File System using copy files (*.cpy) in the following order:

• \Platform

• \Application

Example:

\Application\ScanSamp2.exe>\Windows\ScanSamp2.exe

This line directs CopyFiles to copy the ScanSamp2.exe application from the \Application folder to the \Windows

folder.

Non-FFS Partitions

Non-FFS partitions include additional software and data pre-loaded on the MC32N0 that can be upgraded. Unlike

FFS Partitions, these partitions are not visible when the operating system is running. They also contain system

information. Non-FFS partitions include the following:
