I'm using a CF IDE Module as the "only" storage device on my system. This
is were XPe resides and is booted from.
With Flash Media, should EWF be enabled? If so, what are the recommended
settings.

Thanks,
Richard
 
Thanks for the link, it helps alot. Now, Since I'm a little slow
sometimes. What if I wish to create an image, install and let it FBA. Now
I have a few drivers and settings I want to make for the final config. I
planned on simply making a ghost image to other flash for the other systems
that way they are ready o run with all the current settings.


My question is, with EWF, will my register changes be saved? Or do I have
to make all my changes first, then do EWF?
Does EWF stop all writes or reduce the writes to flash?

Thanks
 
You need to get those changes in there without EWF being on, EWF will stop
all writes to the drive.

Or will need to commit EWF cache or "commit and disable" if EWF settings are
stored in the registry.

CP,

This is true if you're talking about RAM overlay.
If the device is without an overlay volume store you can only disable EWF by committing the current RAM overlay to the protected
volume at the same time. You need to properly shut down the device, so the data will not be lost.
You can call commit at any time, but nothing will happen. Only one internal flag in EWF driver will be set. EWF driver will write
content of RAM overlay to disk during the file system graceful shutdown or restart.

I thought that EWF could just cache all updates to RAM (or whatever you've specified as the overlay) and write them to the CF on

Shutdown. Is that not the case? My application keeps a log as it runs and I need this info. to persist (on CF) between reboots. Can
I do this with EWF enabled?
