Regmerge is configured to look in 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. The SDK contains examples of .reg files.
Note: Regmerge only merges the .reg files on cold boots. The merge
process is skipped during a warm boot.
Typically, you should not need to make modifications to registry values for drivers loaded
before Regmerge. However, sometimes during software development, you may need to
modify these values. Since these early loading drivers read these keys before Regmerge
gets a chance to change them, you must warm boot the terminal after a cold boot. 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.
CopyFile
CopyFile 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 re-boot. During a cold boot CopyFile looks for files with a .CPY extension on
the FFS partition. 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 default application partition shipped with the PDT
8100.
