Re: Problems with Booting XPe from CD-ROM


Yeah, the problems were all over the place. I could get XPe to boot from CD
on some systems and not others. I even tried the clean registry, but even
that didn't work.

Now that CD-boot seems stable in FP 2007. It would be nice to make the El
Torito driver a non-PnP driver like it was in NT Embedded so we wouldn't
need the Pre-FBA CD. Booting from CD is slow, and with USB boot available, I
am not sure how long CD-Boot will be around.

Sean,

Run EWFMGR before ETPREP -all in the same session. It must be done before
you reboot the OS; otherwise you cannot get here from there.

Yup, this is what I was trying to uncover. Thanks for confirming.

Like I said someone else (I think it was Slobodan) found this trick. I
tried it in SP2, and it worked. The reason you had to delete the keys was
because ETPREP did do it what was suppose to do.

Exactly. Etprep (RTM, SP1) wasn't doing that for me (and some others here)
so we had to clean the MountedDevices key manually. But my point was that
this was the only trick required.

In FP2007, the steps in the book still hold - my only addition is the
EWFMGR. If EWFMGR c: -enable step is not needed, great! One less step out
of the 2 dozen.

Sean,

When you say "run EWFMGR c: -enable *before* Etrpep -all" do you mean
the same session or with a reboot in between? I can't imagine a reboot
there, though. But I can't see a need for ewfmgr command during one
session either.

For me it'd always been more stable to manually delete the
MountedDevices key rather then running etprep commands when it comes to
EWF RAM Reg more.

Booting from CD-ROM has always been a hit or miss task. FP2007 seems to
be much more stable.
With SP1, I didn't find the need for the EWFNGR step as you pointed
out, but others found it was needed. Creating a bootable CD-ROM with
SP2 was much worse. ETPREP was notworking as expected. Slobodan and
others had found all sorts of tricks with registry keys that had to be
done. If you look at the history, running EWFMGR before ETPREP was part
of the solution.

I have kept the EWFMGR step as a legacy. It works, and it it works it
doesn't need to be fixed. The rest of the steps still hold.

Sean: Regarding step 4 below: I haven't seen a need to manually issue
an enable command to EWFMGR when running etprep. Etprep takes care of
adding the registry keys needed to run in RAM (Reg) mode and deletes
the EWF volume, negating any changes to EWF's RAM-mode configuration,
so that call to EWFMGR would seem superfluous. Could you briefly
explain what that extra step is about? (Or is it that the extra step
was needed in SP1 and is no longer needed in SP2 and above?)

1. Are you using FP2007? There have been some improvements.
2. With the two partitions on the disk, I assume the rest of the
drive is left unpartioned. Is this Correct?
3. Is EWF set to NOT run on start?
4. One extra step that has changed the instructions from SP1 to SP2
to FP2007, is the need to run EWFMGR c: -enable before Etrpep -all.
5. Are you using the HD2ISO utility to create teh ISO images?

When the image reboots after etprep, the image on the drive will
almost always BOSD. there is nothing that can be done to the final
image. Just create the final ISO.

Why Taskmanager Shell is behaving differently that Command shell is a
bit of a mistery. I just went through the steps for a customer
recently and Command Shell worked just fine.

Hello,
I've tried to boot a XP Embedded image from CD-ROM like described in
Chapter 11 of the XP Embedded Advanced book from Sean D. Liming. My
target is the Pentium based VMEBus Single Board Computer VR9 from
SBS,
the HD is a 6 GB Microdrive from Hitachi, my drive is the DVD-R/-RW
drive SD-R6112 from Toshiba. Because there is no possiblity to
connect
further IDE devices to that board, I've connected the driver via an
adapter to an USB port of the target board.
The image has been generated by first importing the Target Analyzer
informations about my target board and then adding the necessary EWF
and El Torito components and the Command Shell like described in the
book.
The first problem I have encountered is that after having booted the
image from disk with the Pre-FBA El Torito Disk in the drive ewfmgr
reported "Unable to find an Ewf volume" and ewfmgr c: reported
"Failed
getting protected volume configuration with error 1" also the
contents
of fbalog.txt showed that the EWF volume had been created. Diskpart
also found the 32 KB EWF volume after the two primary partitions I
had
created on the disk (C: 160 MB, D: 900 MB). Furthermore the El
Torito
disk had not been found.
I've solved this problem by replacing the Command Shell component by
the Task Manager Shell like in the EWF example in Chapter 10 of the
book from Sean Liming. Now my el torito disk had been found and
ewfmgr
and ewfmgr c: yielded the expected outputs like described in the
book.
In the explorer the following three partitions were visible:
C: 160 MB
D: 899 MB
F: 160 MB
E is the DVD drive. I assume that F is the El Torito drive generated
by the El Torito driver.

But now if I call etprep -all I get the following messages:
Deleted EWF partitions = 1
Start value for Redbook/IMAPI services has been reset to zero.
Failed to swap El Torito disk drive letter. Error = 0x1.

After that the system automatically reboots which ends with a BSOD
with the following outputs:
STOP: c000007b {Bad Image}
The application or DLL \??\C:\WINDOWS\system32\shsvcs.dll is not a
valid windows image. Please check this against your installation
diskette.

Every reboot brings this Blue Screen again.

So my two questions are: Why I need the Task Manager Shell to let
the
El Torito Disk found and let ewfmgr find the EWF volume and why the
swapping of the disk drive letters get failed (I assume that the
Blue
Screen is a consequence of this). I've read in a message on this
topic
that USB drives will not function. Is this really true?

Who can help me? Any hint will be appreciated.
