Chapter 5 Features in Windows XP

Embedded

TPC-1261H supports the embedded Windows platform. This section out-

lines the important features (EWF and HORM), that are provided in Win-

dows XP embedded.

5.1 EWF

EWF stands for Enhanced Write Filter. It provides an upper filter in the

storage device driver stack that redirects disk write operations to volatile

(RAM) or non-volatile (disk) storage. EWF protects a volume from write

access. The benefits are as the following.

Write-protect one or more partitions on your system.

Enable read-only media, such as CD-ROM or flash, to boot and run.

Prolong the lifespan of write-sensitive storage, such as CompactFlash.

TPC-1261H XPE provides EWF RAM RDG mode on system partition.

All wirte to system partition will be redirected to RMA once this mode is

enabled. This mode is manually enabled by customers after they finish

all their changes on system such as installing their applications or adjust-

ing system setting.

Advantech provides a pair of utilities to operate EWF, OSLock and

OSUnLock. The setting is stated in the section later.
