Hibernation and EWF

You can configure your run-time image to boot from a hibernation file with Enhanced Write Filter (EWF) enabled. The following list shows the benefits of booting from a hibernation file:

• Quicker boot time
• Ability to define the state of a system by booting with specific applications and services running
• Support for Hibernate Once/Resume Many

Because EWF starts after the hibernation file is loaded, you can successfully boot from, and save to, a hibernation file.

Note   Use of EWF with hibernation is supported only in RAM modes.
