keyboards do not require special drivers to function. If the keyboard has some special function keys you can download the software from the manufacturer, or map them yourself to whatever command you like.
The company that made the keyboard, NISIS, has dissapeared, and so has their website.
This keyboard does require special drivers to function. I tried installing it the usual way, and it doesn't work. One orange light on it appears.
Unless ofcourse I'm doing something wrong, in which case, enlighten me.
