IRQL_NOT_LESS_OR_EQUAL and EWF

sometimes when i reboot my XPE, i got blue screen with the message
"IRQL_NOT_LESS_OR_EQUAL".

i googled this, someone suggest to always include EWF in XPE image to
avoid this problem. is that true? i don't understand the connection
here. can anyone explain this to me.

thanks!

mike,

That is a bad one. I suppose you already looked here:
http://groups-beta.google.com/group/microsoft.public.windowsxp.embedded/search?hl...

Do you have EWF enabled on the image? What mode of EWF you use?
Does the BSOD screen show the faulty driver?
Were there any errors in FBALog.txt?
Could you check the Ever Viewer log to see if any error appears there related to the BSOD?

I couldn't quite understand your second sentence. What you meant by "always include EWF in XPE image"?

Are you working with SP2? (EWF on SP1 had some problems on certain MBs).

And, very good approach would be to connect to your target with a KD (Kernel Debugger, WinDbg) from another computer and catch the
blue screen to investigate more the call stack.

KM,

i just read somewhere which mentioned always add EWF components in TD
to the image. since i am not booting from read-only media, i don't
understand why i need EWF componennts at all.

this doesn't happen consistantly on the system, i just installed my
image on a system, it wrote the image to the disk, then reboot; when i
login, it says something like "new hardward detected, it needs to be
rebooted....."(do you know why it always has to be rebooted twice after
writing the image to disk?), so i rebooted, then i got this
"IRQL_NOT_LESS_OR_EQUAL " error. so i turned off the power, rebooted
again, this time, it worked fine.

if i got the error first time, why i didn't get it the second time?
should this happen consistantly instead of randomly??

oh, my image is using NTFS, so i didn't format my disk, just write the
image to it directly, will that cause this problem.

Well, read-only media is not only the application of EWF. But if you system specs do not require EWF, you don't need to include it.

It does't.
Does the new hardware identical to the old hardware where you capture the image from?
Do you use system cloning? If you do, what setings you are removing or keeping?

Also, what new hardward is getting detected? If you click on he notificaiton (or go to Device Manager directly) it will show you.

Anything on that BSOD screen beside the IRQL_NOT_LESS_OR_EQUAL?

KM,

why did you say
------------------------------------------------------------------------------------------------
>>sdimgr myimage.sdi /writedisk:0 /yes

"The approach is pretty dangerous since SDI doesn't deal with MBR
properly. But since you got your image booted, it is not an issue
for you.
What's the SDI file size?
Did you try using Ghost or other cloning tools?
Or, better, did you try formatting the target partition and [x]copying
all the files and folders of your image over there? "
--------------------

- what is wrong with SDI file?? i am worried now......
- the combine size of my image is about 750MB, my hard drive is about
40GB, if i use Ghost, will that create a image of 40GB, which is not
what i want

here is my process:
1.) build the image using TD
2.) copy the image files to a SDI file, the SDI file size is about
750MB, put this image on the network share ( will run "net use y:
\\192.144.0.1\\shared"...

mike,

Please disregard my question about the SDI file size. It wasn't relevant to your issues.

With Ghost you won't end up with 40Gb size. Ghost will only capture the data sectors on the disk and will also compress the image
(you will likely end up with even smaller size than 750M).

When you say "copy the image files to a SDI file", do you mean you used SDI Loader on your dev machine? The thing is that it better
be done on the target to preserve disk geometry parameters. Let me put it this way, to get media to boot you should partition and
format it on target machine. But again, since you got the image booted you may not want to worry about it now.

What EWF mode do you use? Since you are switching from reading *partition* and writing *disk* it should be EWF RAM Reg mode.

And, I suppose, on the step 7 you write a *different* image to CD, not the same golden image you just captured, right?

KM,

- yes, i use SDI loader to create a sdi file, then copy all the files
created by TD to the sdi file.

- i didn't include any EWF components in my image, why did you ask
about EWF? is there something i am missing??

--------------------------------------------
i use "sdimgr /writedisk:0" to write the image to my disk, then did
some configurations afterwards, then create a golden image

on my bootable CD, i use "sdimgr /writepart:c:" to write the image to
the target
------------------------------

- yes, the image on my bootable CD is the same as the one i created in
Step 6: golden.sdi

- if i use Ghost to capture the post-FBA and post-Fbreseal image, when
that image generate unique SID once it's written to the target and
then rebooted.

mike,

I apology. I forgot that we already discussed the EWF points.
But now I have to back up and ask you again how you're creating the bootable CD? Do you use El-Torito technology to create one? How
then you avoided EWF?

Where exactly you are seeing the BSOD? Booting off the CD or hard drive?

Ghost would work better around deploying disk data but nothing is perfect. Sometimes you have to use -IR switch to fix some MBR/BPB
related issues and then issue gets bigger.

KM,

here is what i did, i got it from google group with a few of my own
comments added, but i cannot find the link anymore
--------------------------------------------------------------------------------------
create DVD
Required:
1) Embedded Windows XP SP1 Disc 1
2) Windows XP Professional installation Disc
3) Download http://nu2.nu/nu2files/bcd111.zip or the latest version of
BCD (Build CD-ROM) on http://nu2.nu/bcd.
4) Download http://nu2.nu/nu2files/bbie10.zip or the latest version of
BBIE (Bart's Boot Image Extractor) on http://nu2.nu/bbie.
5) Optional to burn ISO Image. Download
ftp://ftp6.nero.com/wnaspi32.dll.

Here are the steps:
1) Make a temporary folder C:\BuildWinPE (where C: can be any drive and
BuildWinPE can be any directory name)

2) Extract with directories the bcd111.zip to C:\BuildWinPE. It will
create a 'Bin' Directory.

Mike,

I see. You used Bart's tools. This is different, not EWF required (WinPE approach).
El-Torito standard isn't related to EWF directly but Bootable CD on XPe (that is El-Torito based) does require EWF though to prevent
the OS to write to disk: http://msdn.microsoft.com/library/en-us/xpehelp/html/xeconElToritoCDAsDisk.asp.

Now coming back to your original post, what else do you see on the BSOD screen? You'd need this info in order to proceed with the
issue investigation as you have no other information available about the fault driver.

Another question, do you see the problem occurring if you do not clone the image (do not run fbreseal). Just do a few reboot on the
final image to verify that.
