Using EWF when booting from ramdisk

[David Harris]

The system I am developing requires frequent updates to the XP Embedded
application and only has a very small hard drive. To make life easy I network
boot from an SDI file loaded as a ramdisk (memory use and boot times are not a
problem). This system works well and is flexible enough to allow me to quickly
modify the images to fix any problems that arise on a particular client.
However you cannot make any system updates on a particular client device that
will be persistent across reboots because the ramdisk image cannot be modified
on the server.

What I would like to do is to set-up a disk-based EWF so that it provides
persistent storage of data across boot operations. If I read the documentation
correctly this is not possible because the EWF can only protect physical
devices. Can anyone think of a way that the EWF can be used to 'protect' a
ramdisk-based drive.

Unfortunately this can't be done. (Well it can but not with EWF SDI
combination).

You will have to write your EWF for this purpose, or to use different
solution.

One possibility is to use virtual remote disk from server. (For both boot
and storing changes).
Check http://www.vci.com/ for some possible solutions.
