68 Preparing the Script Files for Deployment Using Microsoft Windows PE
External Dependencies
The DT_PLATFORM variable is set by TKENVSET.BAT using platform
discovery.
The WININST.BAT script uses the UNATTEND.TXT file in conjunction
with WINNT32.EXE utility to install the operating system files. See
"UNATTEND.TXT" on page 68 for more information about preparing the
UNATTEND.TXT file.
Specifying the Windows Installation Variables and Installation Paths
To edit the Windows operating system installation variables, locate the
following lines in WININST.BAT:
:: The location where source files for the OS reside
set DT_OSSRC=%DT_DRIVE%\W2K3SRC\I386
:: Location of Unattend.txt file
set DT_UNATTEND=
%DT_SYSTEMS%\%DT_PLATFORM%\unattend.txt
After you have either confirmed or edited the Windows operating system
installation variables, you are ready to prepare the UNATTEND.TXT file to
be used in the operating system installation.
UNATTEND.TXT
The UNATTEND.TXT file is the default name of the answer file that you
use to automate Windows Setup during an unattended installation. A sample
copy of the UNATTEND.TXT file is provided as part of the DTK download
in the \Toolkit\Template\Configs directory. UNATTEND.TXT contains the
headings and parameters that instruct Windows Setup to perform various
configuration tasks. Before a full deployment can be run, you must edit all
appropriate headings and parameters, as necessary.
NOTE: See your operating system documentation for instructions on modifying the
options in the operating system unattended installation file to customize the
scripted installation of your operating system.
When you have completed all necessary modifications of the
UNATTEND.TXT file, save the completed file in the
\Toolkit\Systems\<target system> directory.
