Creating/Loading Hex Images 6 - 19
Platforms partitions folders. Take care when using Regmerge to make Registry changes. The MC1000 DCP
contains examples of .reg files.
Typically, do not make modifications to registry values for drivers loaded before RegMerge. 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 mobile computer 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. A cold
boot copies files 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 “>”. The following example from the file application.cpy is
contained on the demo application partition included in the MC1000 DCP. Also obtain this from the Support Central
web site at http://www.zebra.com/support.
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 mobile computer 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:
• Windows CE: The complete Windows CE operating system is stored on Flash devices. If necessary,
download the entire OS image to the mobile computer using files provided by Zebra. The current OS partition
on the mobile computer is included as part of the TCM installation package. Obtain any upgrades from Zebra.
This partition is mandatory for the mobile computer.
• Splash Screen: a bitmap smaller than 16 Kb (and limited to 8 bits per pixel) appears as the mobile computer
cold boots. To download a customized screen to display, see Creating a Splash Screen on page 6-17.
• IPL: This program interfaces with the host computer and allows downloading via cradle or serial cable any or
all of the partitions listed above, as well as updated versions of IPL. Use caution downloading updated IPL
NOTE Regmerge only merges the .reg files on cold boots. A warm boot skips the merge process.
NOTE 8 bits per pixel only applies to splash screen images. Once Windows CE is running, the color density is 16
bits per pixel.
