Insert CD2 Notification on W2K3 R2 Install

[Kjhe]

Does anyone know how or where to disable the notification to insert the second CD after the first login or what triggers it in an W2K3 R2 install?

Thanks!

Just discovered by myself how to make the CD2 notification disappear. It appears the CDKEY used is "recognised" as a R2 key by the installation and thus brings up the dialog, and does not appear to be the result of differing files on the CD itself, whether a R1 or R2 CD was used.
