I have made my driverpack enabled CD work with remote installation (RIS), and would like the 'hack' incorporated in the standard script so that it will work for everyone.

Remote installation for XP copies the entire content of the install CD to \$win_nt$.~ls\ on the install hard drive. The second stage of installation proceeds from that folder 

The location of the driverpacks install is discovered in the script  %installdrive%/i386/presetup.cmd

SET TAGFILE=\OEM  
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) DO IF EXIST "%%i:%TAGFILE%" SET CDDRIVE=%%i:& GOTO DPsFound
:DPsFound

I suggest the following instead, which makes driverpacks for XP RIS compatible:

SET TAGFILE=\OEM  
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) DO IF EXIST "%%i:%TAGFILE%" SET CDDRIVE=%%i:& GOTO DPsFound
IF EXIST "\$win_nt$.~ls" SET CDDRIVE=\$win_nt$.~ls
:DPsFound

The line inserted will never run unless the tag file isn't located. I can't imagine any bugs this could introduce.
