Hello all!

I'm developing an embedded system using Xpe Sp1.
I want the final image to be in Compact Flash.

My custom application will be the only app running in the system, that is,
the custom shell of the system.

This app does not write anything to disk. So if i disable disk swapping and
defrag service, do i still need the functionality of EWF?
Can i bypass the write filter at all? Obviously i don't want the system to
be writting to the CF.

Thanks a lot for your help.
Great job!
 
Sorry i've just read the Xpe & CF question which is the same question.

But.

Does XPe really write something to registry? What?

Thanks a lot.
 
Does XPe really write something to registry?
Yes it does.
What?
Click to expand...
I don't think that there is a list of all drivers services, applications,
etc that write to registry and at what condition.
For instance PnP can detect something new and install drivers. Time service
could try to change daylight saving. Some app can try to record a time when
it was last started or to decrease/increase some start counter.
There is no 100% safe way for you to know when something will try to write
to registry.

Slobodan

Alberto,

This is pretty strange question if you know registry data centric structure of Windows platforms.
Run Regmon (www.sysinternals.com) tool at your runtime to see how much is getting written in to registry (you can even create a
filter to see only write access).
 
Thanks for the last tips.

I've got another little question please.

It seems that i will have to protect the flash with EWF. But i will only
need to "drop" all the write attempts to CF. Will EWF use the same amount of
RAM memory as the disk space i would like to protect?
That is. If i have a volume of 128 MB of flash, do i will need 128MB of
extra RAM for EWF?
Is there any other way to do this with a low memory configuration?

Thanks a lot.
