21A error during boot

[Piotr Rezmer]

Hi,

During boot process I receive: ..0021A FATAL SYSTEM ERROR that relates to
WinLogon. I use CF with EWF. Image was transferred using HD with EWF. I
followed help instructions, finished FBA and so on. Ewf was enabled on HD.
Then I connected HD and CF to laptop and copied HD contents to CF. When the
target system is started I see splash screen, then blue wallpaper and after
a second, bsod with the error message.
Following help file, 21A is related to disabled EWF, but I suppose that it
is not the case.
The other strange thing is that I don't use Winlogon but MinLogon.

Did anyone meet such a problem before ?

best regards
Peter

Peter: What EWF mode are you using? If you are using a RAM or Disk Overlay,
your runtime will not function properly when you copy the image to CF,
because EWF depends on a custom partition that was automatically configured
during FBA. This partition (called the EWF partition) stores configuration
information (and in the case of a Disk overlay, it stores the actual overlay
as well), and without this partition, EWF cannot function.

If you're going to use a CF card, you should configure EWF for RAM REG
operation. See this article for more information:

This is RAM overlay

I thought that RAM overlay doesn't use any physical partition to buffer
data, only memory.

operation. See this article for more information:

I did exactly (at least I think so) as in that article and the last (15)
step is to copy intermediary HD to CF. When they say "runtime image" I
suppose they mean system files, not whole disk with all existing partitions
(specially EWF). Maybe here's something wrong and I really need to transfer
partitions not files. Is there any way to copy EWF partition ?

If you're going to use a CF card, you should configure EWF for RAM REG
operation. See this article for more information:

Could that be a problem that the HD is connected to primary IDE and CF is
connected to secondary IDE ? In both cases there's only one device connected
at a time, so it shouldn't change drive letters and numbers ?

I added volsnap value to registry and now the system is booting completely.
There is Volume shadow copy service, which is required by WMI core.
Unfortunately I don't know which module requires WMI core. I have XPe tools
installed in TD, but derive explorer doesn't work.

To get rid of VSS delete the following components from your design in TD:
- Indexing service..
- Filter MIME Mess..
- Volume shadow..
- WMI core..
- Distributed ... (MSDTC)..
- COM+ Services

Hope this helps

I can't delete WMI core since it's related to networking. Target system
should have networking and windows installer feature.

Depending on what kind of networking you need, you can remove WMI. I have
systems that include TCP/IP and IE for browsing over a network/router w/o
all the above components.
I don't know if the installer really needs WMI.

Installer needs MDAC which requires COM+ services . I need installer to be
able to upgrade middleware.

Hi again. A RAM overlay does not store any writes to the EWF partition (it
instead puts them in memory), but it still depends on the EWF partition for
configuration information. This is what distinguishes a RAM overlay from a
RAM REG overlay.

It looks like you've resolved the problem - glad to see it worked. =) Just
wanted to clarify the difference between RAM and RAM REG overlays.

Piotr,

doesn't work.

Sorry for late response. I've been out for quite a while.
You should not use DeriveExplorer from XPeTools package. That component is .. very special and was only to explore some hierarchics
in the database.
What you should use here is ConfigurationExplorer. It will show you what components in the configuration depend on the specified
component (you will be interested in the dependent components list).
