Attempt at booting Windows XP embedded on a USB Stick

1. In an attempt to get away from the switching
drives i thought that using a usb key might
be a better technique, i.e. just plugging
in the usb drive and unhooking the main
ide drive (or removing it using a drive
tray)

2. To create a bootable usb stick the
following givens must be met:
a. The pc that you intend to boot of off
must support booting of a usb key.
b. you must have access to a pc that
has a high density 3 1/4 floppy drive.
c. install dos, in my case dos 6.22
these can be fount at http://www.bootdisk.com/
onto a 3 1/4 floppy.
d. download and install the program
"SP27213.exe" which you should be able to
which is make available by the hewlette packard
compnay, and can be located on HP's web site.
see the website
http://www.novell.com/coolsolutions/feature/3612.html
for a snapshot on how this works.
when you use this utility and you click
"Create a Dos startup disk"
point the directory button to the previosly
created dos boot floppy. This will
copy the dos boot sector, msdos.sys and io.sys
to the usb key drive. The drive will now
be able to boot. after that I manually
copied all the dos files from the floppy
dirve to the usb key drive.
The usb key should now boot to dos.


This above my a working usb dos pen drive.
I attempted to convert this into a drive
into something that was capable of booting
windows xp embedded for this i had to bootprep.exe.

From Sean Limingsbook's Windows XP Embedded
Advanced Chapter 8.2.2.1 "BOOTPREP.EXE prepares
your media, whos active partition has been
formatted and made bootable with FAT16, BIGDOS FAT 16
or FAT32, for booting into Windows XP Embedded."

I booted the usb key into does ran bootprep.exe
then restarted and place a pre-fba boot image
onto the usb key. After restarting the
computer Windows XP embedded attempted to start:
I had the initial white on black progress
bar and the windows XP embedded splash screen
but immediately after that. i had the following
STOP screen with the STOP code
0x0000007B (0x f894d640 , 0xc0000034 0x0000000 0x00000000)

Then I did some research on
