Thanks for your reply, MrJinje, much appreciate. Unfortunately, Catalyst drivers aren't on the OS (windows 7) due to lack of ATI graphics card. I'm able to integrated other drivers i.e. Ethernet, Audio, Chipset, etc. The only obstacle that stand in the way of completing an unattended Windows 7 DVD that I'm working for a custom built PC (WIP), is the ATI Catalyst driver. Ugh! I just thought if anyone had any solution..... Thanks.
