Chapter 5 Windows XP Embedded
TPC-1770/1780 is in support of embedded windows platform. This sec-
tion is to state the important features, EWF and HORN, 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-1770/1780 XPE provides EWF RAM RDG mode on system parti-
tion. All wirte to system partition will be redirected to RAM 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
adjusting system setting.
Advantech provides a pair of utilities to operate EWF, OSLock and
OSUnLock. The setting is stated in the section later.
5.2 HORM
HORM stands for Hibernate Once Resume Many. In HORM environ-
ment, a single hibernation file is used to boot the system repeatedly. To
set a HORM environment, please follow the steps below.
Please make sure EWF is disabled. You can run OSUnLock to disable
EWF.
Enable hibernation support:
Run ‘power options’ in control panel, and then select ‘Enable Hiberna-
tion’ in hibernation pane.
