C.1.1

Introduction

Enhanced Writer Filter (EWF) is a feature supported by Windows XP
Embedded and it provides the ability to write-protect a run-time image.
By redirecting all write requests to RAM, the EWF allows the run-time
image to maintain the appearance of a writeable run-time image, prevent-
ing any damage that might be caused by unexpected power failure, vibra-
tion or virus attack.
Advantech provides a utility called "Advantech EWF Manager" to help
adjust the EWF setting. The instructions follow below.
