I have create an unattended installation for win2003r2 I have put all my drivers in the $oem$\$$\Drivers on the cd. Everything works fine with them. But when i delete these files after instalation, everything still works fine. I know windows keeps most drivers in C:\WINDOWS\system32/drivers But there are only .sys files. I have also .cat and .inf file for the chipset (no .sys for the chipset), where can i find these back in the system32 folder? ??
