DOS Command-line Tool Boot Commands

The following table lists the EWF boot commands that are supported.

Boot Command

Description

All

Displays information about all protected volumes and performs a command, such as 

disable

, 

enable

,

and 

commit

, on each volume if specified.

Commit

Commits all current level data in the overlay to the protected volume, and resets the current overlay
level to 1 upon shutdown.

Disable

Allows user to write to the image after the next reboot.

Enable

Prevents the user from writing to the image after the next reboot.

Commitanddisable Combination of the 

Commit

 and 

Disable

 commands. This command will commit data in the overlay

upon shutdown. Additionally, EWF will be disabled after the system reboots.

NOTE:

When using the Commit boot command, all the temporary contents will be permanently

written to the flash memory. In addition, all content accessed (and changes made) after running
Commit, but before rebooting the system, will be written to the flash memory as well. This includes
changes made during any number of login/logout sessions before the next reboot.

Using Boot Commands

To use the EWF manager boot commands, type the following syntax in a command prompt:

EWFMGR <drive-letter> —[boot command]

.

NOTE:

Because the EWF manager commands are executed on the next boot, you must reboot the

system for the command to take effect.
