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.

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

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]
