Hi, I am creating my windows xp cd, I dont need it to be unnattended, Im using WPI to install soma applications like office, I have copied all the programs to a folder in the compilation, the file WPI.cmd is in the $OEM$\$$\system32 of the CD, and is modified and looks like these: @ECHO OFF REM Example, how to look for CDROM-drive. Must have WPI.ico at the root of the CD. for %%i in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist %%i:\WPI.hta set CDROM=%%i: echo Found CD-Rom as drive %CDROM% REM Determine the WPI startup path. REM if wpi should run off the cd the replace %~dp0 with %cdrom%. set wpipath=%CDRom% REM Hide this command window. %wpipath%Common\cmdow.exe @ /hid REM Special registry tweak needed. regedit /s %wpipath%common\wpi.reg REM Make WPI directory the current directory. cd /d "%wpipath%" REM Start WPI and wait for its end wpi.hta REM Undo registry tweak. regedit /s %wpipath%common\undo.reg exit My WPI folder is in the root of the CD. Is the WPI.cmd in the right place, and is the script correct?? And then, what should be written in the winnt.sif file and where in the compliation shoul it be??? Thank any help shoul be nice.
