The SCR 3232 does not have a Parallel Port interface as you have indicated. It has a IDE (ATAPI) interface. It would have to be external in order to have a parallel port interface.
As I have stated in numerous threads, optical drives never require a driver when used in all Windows OS's beginning with Windows 95.
If you want help, start out by tell us what the problem is and include a few details from Device Manager and My Computer. Is the drive listed in My Computer? If not that's considered "non-detection". There are a few things that can cause non-detection:
1: IDE ribbon cable not connected properly or a bad ribbon cable or connector. Or power cable not plugged in or loose.
2: Wrong IDE controller driver installed.
3: IDE port is not enabled in pc bios setup.
4. Bad or incorrect firmware flash attempt.
5: Defective drive.
An optical drive is installed automatically by the os... not by manual installation like other hardware, using a driver. Windows does not provide any notification of it being installed either. In fact you won't know it until you look in My Computer or Device Manager or Windows Explorer and see it listed there.
