Anthony,

Here's my procedure which has worked pretty much every time. Hope you
can adjust to your situation. Forgive the length.

Assumption: You're using two drives (one with regular XP and your XP/e
design software; the second is the target device). If you're juggling
partitions on a single disk, specifics change. I'm using the standard
XP Explorer interface so need a fairly large partition even before my
application is added. Also, I'm using the standard EWF components,
not Slobodan's modified component (nothing wrong with it, I just don't
use it).

1) Create 2 primary partitions on target disk; format both as FAT,
make 1st active. Example: both are 600MB but keep the test load on the
2nd small so you can do simple test on CD's not DVD's.
2) Use Target Designer to build image on 1st partition; load read-only
CD portion onto 2nd partition. I set EWF to start disabled.
3) Use Nero to start a bootable CD compilation using 1st partition and
add files from 2nd partition to data part of the compilation.
4) Have Nero create an ISO image file using Image Recorder device.
5) Run Slobodan's tool to set disk signature of ISO file.
6) Restart Nero and burn ISO file to CD; this is your 1st boot CD that
must be present during FBA so Torito.sys can initialize correctly
during the plug & play portion.
7) Shutdown and boot off target disk through FBA. Should reboot
twice. Must have 1st boot CD online.
8) After FBA completes, on target, open cmd window and look at
fbalog.txt in c:\windows\fba; Near the end, you should see it identify
the Nero CD as El Torito and EWF should end with 0 status.
9) Do any other post-FBA steps (keep simple for this test).
10) Prepare target for burning. My steps are: make sure 1st boot CD
is present and seen as El Torito, open cmd and verify EWF is running
and disabled. Use "ewfmgr c: -enable", then "etprep -delete". Start
REGEDT32, go to HLM\System\Mounted Devices, delete all the
"\\??\volume..." entries & the entry for the C: drive. Rename the El
Torito drive entry to be C:. Exit
11) Turn off computer.
12) Reboot off development disk with target back to being data.
13) Repeat steps (3) to (6) except this time you should have the real
thing, a bootable XP/e CD.
14) Try it; good luck & hope your situation is close enough to mine
that these steps make sense to you.
