here is the boot string that you will need to modify..

Code:

$boot = 'c:\boot.ini'
$defaultboot = ReadProfileString($boot,'boot loader','default')
$DefaultBootString = ReadProfileString($boot,'operating systems',$defaultboot)

? $DefaultBootString


Now i have sp2 installed, so i have "/noexecute=AlwaysOff" installed by default, you will have to do some string checking to see if this switch is not already in the default boot string so you can change it from its dafault setting, or add it if it is not.
