  • Ive searched..and nothing.. What does EWF and HORN actually do for me?

    Can anyone explain?

    Right now I am just planning on using nlite to cut down my windows.

    I am going to have plenty of hard drive space (120 gigs), and I will be using the hibernation feature for fast start-ups.

    What are the benefits of using EWF and HORN?

    EWF redirects writes that would usually go to your hard drive to ram. By reducing the number of writes you can make solid state drives last longer.
    HORN is used to make people get out of your way. Often it's the button in the middle of your steering wheel.
    HORM on the other hand (which is what I suspect you wanted to ask) allows you to reboot from a single hibernate image multiple times. It allows a fast boot from a stable image with no requirement to hibernate on shutdown.

      lmfao..that is what I get for posting at 4am.

      Thanks for the input. It looks like I would really only be interested in HORM. Even then I may just do a regular hibernate.

      That is assuming the intelligent power supplies for sale in the store here can handle hibernation/waking when my car stops/starts.

        Most do, that's what the (usually integrated) shutdown controllers are for.

          So what exactly does a CarPC with HORM do when you turn off your car? It doesn't need to copy your RAM to an image, so does it just turn itself off immediately, and when you power it back on, it will know to resume from the stable image?

            I am guessing that it saves the Image one time. It never deletes or changes that image. So every time you boot up, it will be from that one image.

            So you will only be saving time on the shut down process because you will never need to re-write a new boot image.

              like others stated already, with HORM you don't need to worry about shutting down cleanly. even with total power loss or a crash the system will boot back up like normal. one scenario would be keeping the carpc on standby with a power supply which kills the power when the battery gets too low.
