THis was (I believe) the last driver set released by Real3D. It was supported only briefly before the company went belly-up. Probably had a few problems with DirectX6, but works well with DirectX5. Designed to be used with the 147 BIOS, and works with DirectX 7 (personal experience). Flash to 147 BIOS BEFORE using these drivers for most stabilty, but I suggest going back down to the 288 drivers afterwards if you have any trouble.
