Enable EWF:
Run OSLock, and then system reboot automatically.
Open those software that customers want to directly use after system
resume from hibernation.
Hibernate via Advantech HORM utility:
Please Click Start Menu->All Programs->Advantech->HORM
HORM environment remains all along unless the following events occur:
Run EWF commit command (ewfmgr c: -commit) and then reboot.
Select “Discard hibernation file” by clicking F8 when system is starting
Also, HORM cannot fit your system if free space in C partition is not
enough. The hibernation file required is dependent on the RAM size you
use on the system. In other words, the hibernation file is 512MB that is
the same as memory size used on TPC-1770/1780.
5.3 Advantech Utilities
5.3.1 Version Information
Start menu-> All Programs -> Advantech
This states the current XPE runtime information including hardware plat-
form, version, build number, release date, XPE QFEs installed in compo-
nent database and XP Pro Patches you installed manually.
5.3.2 EWF Enable and Disable
The two utilities assist users to enable or disable EWF. Please go to Start
Menu-> All Programs-> Advantech. The default setting of EWF is dis-
abled. Users can protect C partition from any disk writing via OSLock

partition including modification on files or registry will be redirected to
memory, thus these changes will be discarded in the next system startup.
To exit this environment is via OSUnLock. Please visit MSDN website
for further information about EWF.
