Hi

I have finished my app now and configuring EWF. I have been using a hard
disk for development but my target application will run from CompactFlash or
DiskOnChip.

I have read the documentation on EWF but I am still not clear on a couple of
things. I need to be able to make registry changes and install applications
on my target device. If I configure using a RAM overlay then I will lose the
data on reboot. If I use a DISK overlay will I still get good write
protection if I run from a Flash device?

If I use a DISK overlay what EWF partition size should I use?

Best regards

Paul Cuthbert
