Qn - How to Build a system with persistent storage??

Hi Guys,

May I know if there is any documentation/guide on building a WinCE 5
system with persistent storage and hive registry?

I tried building the system by choosing hive registry and rom-only file
system, it built successfully but cannot run. With a rom-and-ram file it
run fine, but the hive registry does not seems to be working, as changes
to the system options are lost after power off.

Therefore, is selecting hive registry in the catalogue suffice for
hive-based registry system.
Similarly, is selecting a rom-only file system sufficient for a system
with persistent storage.

Thanks for your help.

Hi,

selecting the catalog items is not enough. For a CEPC platform, there is
buildin support in the registry, but you must set
the following environments to enable it:

PRJ_ENABLE_FSREGHIVE=1

enables hive based registry

PRJ_BOOTDEVICE_ATAPI=1

merges the first partition of the harddisk with the rom file system. So that
all files on that partition appear under the "my device" icon. (If you have
explorer running) According to the help, this will only work with a ROM only
file system.
The partition should be properly formatted.

The registry changes are only saved to disk when the registry is flushed.
This can be done periodical, but it also has to be enabled with a
environment setting. I can't remember which one right now.

The registry hive files are saved under "\Documents and Settings" and
"\Documents and Settings\default"
These locations can be changed. Look for the registry key
"HLM\init\Bootvars".
It is evident that the save location must be persistent, or the hive based
registry won't be persistent either.

hope this helps.

regards,

Luc

The setting for automatic periodic registry flushing is:
PRJ_ENABLE_REGFLUSH_THREAD =1

Also the bootable ATAPI disk should be mounted as root:
PRJ_ENABLEFSMOUNTASROOT=1
