EWP-2000 WEB PAD SOFTWARE MODIFICATION INSTRUCTIONS 

 

FOR INSTALLER USE ONLY 

 
This document describes the procedure for updating the persistent Windows XPe Operating System image stored 
on the Escient EWP-2000 web pad. 
 
The EWP-2000 uses a special version of the Windows XP operating system called 

Windows XPe”

. XPe is 

designed to work with embedded systems such as the EWP-2000. The EWP-2000 contains a memory based 
FLASH drive for storing software as opposed to a moving disc based hard drive. This FLASH drive contains the 
Windows XPe operating system and the Escient software for connecting to your FireBall. 
 
In an effort to reduce the chances of the EWP-2000 from being corrupted by end user activities, such as 
downloading programs, viruses, and other malicious software from the Internet, Escient has enabled a 
writeprotect system called 

EWF (Enhanced Write Filter) 

on the EWP-2000. The EWF will allow users to run and 

install any XPe software, but 

will not 

save the software after reboot. This means that the original factory 

installation will be restored after each reboot. 
 
Escient recommends that you leave the EWF on at all times, however you may have a specific need to install 
additional software onto an EWP-2000. You can issue a command to tell the EWP-2000 to 

save the current 

contents 

of the FLASH drive as the default configuration. This means that the current state of the FLASH drive 

and OS will be saved on the web pad as the default. 

 
Note: 

It will be necessary to save the current state of the web pad after setting up the wireless network 

connection in order to maintain this connection after a reboot. 

 
Note

: The command prompt window is accessed by selecting 

Start->All Programs->Accessories->Command 

Prompt 

from the Windows Task Bar. 

 
Saving the Current State of the Web Pad 

Verify that the software installed on the EWP-2000 is exactly the way you want it. 
 
1. Type the following command into the Command Prompt window: 

ewfmgr c: -commit

 

2. Reboot the EWP-2000 by selecting 

Start->Shut Down->Restart 

from the Windows Task Bar. 

 
Turning off the EWF 

If you want to turn off the EWF completely, follow these instructions: 
 
1. Type the following command into a Command Prompt window: 

ewfmgr c: commitanddisable 

2. Reboot the EWP-2000 by selecting 

Start->Shut Down->Restart 

from the Windows Task Bar. 

 
Turning on the EWF 

If you want to turn on the EWF, follow these instructions: 
 
1. Type the following command into a Command Prompt window: 

ewfmgr c: -enable

 

2. Reboot the EWP-2000 by selecting 

Start->Shut Down->Restart 

from the Windows Task Bar. 

WARNING 

Once you save the current state of the web pad, you cannot revert back to the original Escient factory state 
without sending the web pad to Escient for repair.
