Your answer file looks good..
You can test it easily to see how it works.. take a computer, copy your sysprep folder to C:\sysprep ..
Go into dos, go to C:\sysprep
type: sysprep -pnp
It'll run through it's thing, then shut down the PC. If it runs longer than 5 minutes and it doesn't shut down but sits at a blue screen, just turn the PC off. It's had enough time.. the shutdown thing hasn't always worked properly.
At that point, when you turn the PC on, it'll go into the mini-setup.
So after you sysprep and run with the -pnp switch, pull the HD and create an image of it.. I made a bootable CD with ghost.exe, edited the config.sys and autoexec.bat.
It'd boot up and give you 3 options, load PC with ghost image, load PC with CD-rom support, or go into windows normal.
Here's my Autoexec.bat - I'll have to hunt down the config.sys, which shows the menu.
autoexec.bat
@ECHO OFF
path=a:\;a:\ghost
IF "%config%"=="NOCD" GOTO QUIT
MSCDEX.EXE /D:MTMIDE01 /M:10 /l:q
echo.
IF "%config%"=="LOADIMAGE" goto GHOSTSETUP
GOTO QUIT
:GHOSTSETUP
@echo off
MOUSE.COM
MSCDEX.EXE /D:MTMIDE01 /M:10 /l:F
echo Loading Ghost 7.0...
GHOST.EXE /clone,mode=load,src=F:\xxx.gho,dst=1 /sure /rb
goto QUIT
:NOCDROM
echo.
echo Loading OS....
echo.
:QUIT
well, ok.. here's a link that will show you how to make a menu using Config.sys.. it'll call up the autoexec.bat to make it happen.

I have all of my bootdisk here at work except my config.sys, if you want it email me and I'll send you the zip file of what I have.
