Re: Persistent registry (Hive)

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance


You can obtain some info from the "config.bib" file. Post it here and we
will see where the image is executed from.

Yes, if running from RAM it is possible to setup \Flash folder
using the FMD driver, and keep your persistent data files there,
as well as to place registry files there.

Take a look at "ms-help://MS.WindowsCE.500/wceddk5/html/wce50conFlashMediaDriver.htm"
in wince 5.0 documentation.


Overwise (running from flash) you have two solutions:

1. Use Intel PSM, which is not free but time-verified and
quite stable solution.

2. Build you own solution. This is not really very defficult,
all You need is the piece of code for flash write/erase
operations to be copied to RAM and then called from
there, cause the most of flashes can not be read
(ie. no way to execute code from flash) when switched
to command mode.
