knubile... what I tried to do was run -commitanddisable -live which commits changes and disables ewf right away (the live switch), then run -enable (which will enable ewf at the next bootup), and then hibernate. Only problem is ewf doesn't get a chance to enable again before the coming out of hibernation process. I'm guessing that the special ntldr for ewf is what makes the changes, but the hibernation process must come before ewf. I'm also trying to figure out where ewf keeps its state, because the registry values don't change from ewfmgr calls, but ewf must keep its state somewhere.

I may take a look at this readyon as well...

Okay... we're going to feel really dumb now. Doing a few searches on google I found some people trying to use hibernation with EWF on XP Embedded. It turns out that hibernation bypasses EWF when it writes the hibernation file!! The even better part is that it keeps that state throughout reboots! So you don't need to rehibernate again and again (causing writes which is bad for CF cards). So we're set!!! All you need to do is hibernate once with EWF enabled. Then you can just reboot, pull the plug and restart, whatever you want!

HAHA. You've got to be kidding. I'm going to try that right now.

Can you post a link to where you read the info SFiorito?

this is a longass thread, but these two guys cover everything: http://groups.google.com/groups?hl=e...gbl%26rnum%3D4

I got a BSOD trying to return from hibernate. I'm using VMWare on a dell laptop. I think the failure is from VMWare. its some vmware dll mention in the BSOD. Is anybody trying this outside of VMWare and VirtualPC (ie. a real install)?

SFiorito

yeah, i got mine to work from my via system. haven't tried it in virtualpc yet.

So you have your via system hibernated once and resuming from the same hiberfil.sys everytime?

yeah. i had a basic WinXP SP2 install on my via system. I did the EWF process and made sure it worked. Then I just hibernated, rebooted, and it came up fine. I did a normal restart and even just switched the power off and on again and it still resumes from the same hibernation file.

knubile

Awesome! I'm going to do that to my system ASAP. Now I can put my laptop drive in a USB enclosure and take it out of the car.
Time to buy a CF card or IDE flash drive.

So what does ReadyOn do that we haven't just accomplished?

SFiorito

Yeah, that's what I'm trying to figure out... Because from what I read in that ReadyOn thread it seems to use its own filter similar to EWF. I ordered a CF-IDE adaptor and a 1GB SanDisk card. 1GB because I figure the install will be around 350 - 400 MB plus the hibernation file on a system with 512MB of RAM. It's a new CF card with extremely fast (for CF) read/write speed. So we'll see how well it goes!! While I wait for the CF card and adaptor I'm experimenting with nLite to see how small an install I can make that is still functional for what I plan to use it for. I'm planning to keep WMP and IE because I'd like to use them to build my .NET UI. For now though I'll probably just use one of the current frontends just to get the damn thing in my car once and for all. Then I can worry about software issues later.

SWC

I haven't read all of the ready on threat but back when I was following it I remember reading something about them having been the ones who actually developed XPe for MS so it would make sense to me if theyre the ones that wrote that they wouldve written this and maybe theyre just customizing it a bit more for their use.

SWC

I was just browsing price watch and they have 2 gb CF type hard drives for under $100. Why not use these instead of regular CF? In my expierience it hasn't been much if any slower (at least noticeable a diff) than a regular CF card in a PDA (can't say as far as running an os if theres a big speed difference). But for the price, it would seem more practical you're basically getting twice the space for less than half again as much and its not as sensitive to read/writes. I still think its a good idea to use EWF but you dont have as much of a concern. sorry if im babbling on and on I'm really tired and wanted to mention it before I forgot.

Thank you guys man, now I don't have to sell my damn 800mb IDE Flash drive. I'm gonna try it out and see how it goes.
