RegMerge
RegMerge.dll is a built-in driver that allows updating the registry during a clean boot. RegMerge runs very early
in the boot process and looks for registry files (.reg files) in certain Flash File System folders (i.e., \Application)
during a clean boot. It then merges the registry changes into the system registry located in RAM.
The following example uses RegMerge to set a registry key:
SampleReg.reg
[HKEY_LOCAL_MACHINE\Hardware\DeviceMap\Backlight]
“BacklightIntensity”=dword:00000036
The following example uses XML provisioning to perform the same task:
SampleReg.xml
<wap-provisioningdoc>
<characteristic type=“Registry”>
<characteristic type=“HKLM\Hardware\DeviceMap\Backlight”>
<parm name=“BacklightIntensity” value=“54” datatype=“integer” />
</characteristic>
</characteristic>
</wap-provisioningdoc>
CopyFiles
CopyFiles copies files from one folder to another on a clean boot. During a clean boot CopyFiles looks for files
with a .CPY extension in the root of the Application FFS partition. These files are text files containing the
source and destination for the desired files to copy, separated by “>”.
The following example uses CopyFiles to copy a file from the \Application folder to the \Windows folder:
SampleCpy.cpy
\Application\example.txt > \Windows\example.txt
