hibernation

[Mike@Nestor]

Hi !

I am looking for a flag which indicate the return of an hibernation. Does it
exist ??

Hibernation takes less time to boot than standard boot but some devices
prevent hibernation (some video capture cards for ex.), so it would be great
to hibernate from an "idle state" and then return from this hibernation and
indicate to active applications : "ok let's go !".

thanks
Mike

Mike,

Hi !

Yes, it does. Basically it is a "word' at the beggining of the hiberfil.sys file (it changes from HIBR to WAKE). not sure why you
need such flag and how you are going to use it.

Anyway, in this thread you can find all the required details:

In case you happened to have EWF in your image, the SP2's HORM feature may be interested to you:

(this is basically the feature described in the thread above)

You can [temporarily] disable the drivers that do not support StandBy mode.

Hi KM,

I am making a "video streamer" and I'd like this device boot as quickly as
possible and always with the same configuration. So HORM is perfect for me !
But when I boot I'd like my "video streamer" streams automatically. The
problem is that my video capture card prevent hibernation so to hibernate I
must first stop the capture process but when my device restarts, my
application cannot stream
( There are same kind of problems with network applications with openned TCP
sockets)

So it would be great if windows could notify to the running applications
that he has been restarted.

Is there a way to do this ?

You can [temporarily] disable the drivers that do not support StandBy mode

what do you want to say with the word "temporarily" ?

NB. I can do exactly what I want without hibernation but hibernation is very
nice for quick boot

thanks
Mike

You have to properly handle this in your application code. See below on how you can do that.

( There are same kind of problems with network applications with openned TCP
sockets)

that he has been restarted.

Is there a way to do this ?

Look at MSDN for WM_POWERBROADCAST. That is the broadcast message you can catch in your application to properly close any handle to
a stream.

If you process the video at driver level, there is even more control there. (IRPs fro going in to S3, then S4 mode)

You can [temporarily] disable the drivers that do not support StandBy mode

what do you want to say with the word "temporarily" ?

Nevermind. I thought you were talking about a device which driver (or hardware) does not support Standby mode. With such device
enabled, the System cannot go to the Standby and therefore to Hibernation modes. You would have to disable the device (using devcon,
e.g.).
Hower, this does not seem to be your problem.

NB. I can do exactly what I want without hibernation but hibernation is very
nice for quick boot

No doubt

Also, if you happened to have a custom shell for end user and you provide a custom way to hibernate your system you can do whatever
you need to do to clean up any streams/sockets/etc from your application code and then hibernate. Then on resume you always get in a
clean state.

SO NICE !!

thanks a lot KM, this is exactly what I want

Now I can use HORM with a custom shell, the user has no possibility to do an
hibernation (he can turn off the system violently). Hibernation is done only
once by me with my application in idle state. Then the system always
restarts with the same configuration, I receive the power notification
message and my application can launch all of its processes. Excellent

thanks again

Mike -

If you are interested in HORM. You may also want to take a look at a
product named ReadyOn by Ardence. ReadyOn is a complete software package
that provides XP Embedded and XP (desktop) systems the ability to have
Instant On Protection.

http://www.ardence.com/products/instant_on/ReadyOnbrc.asp

If you need more information about the differences between ReadyOn and HORM
please contact Ardence directly (e-mail address removed).
