Operating System: Windows 98SE (Note: might work with other versions of this os.)
These drivers work for Windows 95 and 98SE, but have not been tested on any other versions of Windows.
If you have an NEC Ready 9618 desktop, try these drivers before any others. I didn't have any luck with other drivers on this computer, but these work. Hopefully they'll work for you too.
(Note on this computer, the soundcard is built in to the motherboard, so I wouldn't recommend using these drivers for a normal soundcard with the same chipset. Though it's up to you.)
