I had Windows 2000 RC2 installed for about an hour last night before going nuts trying to fix one problem after another with it (driver related). I promptly re-installed Windows 98 to get functionality back in my system. I should be re-installing Windows 2000 again tonight (into a seperate directory from my current install of Windows, so I can still use Windows 98) since I now have some better video drivers and a better understanding on how to install current drivers.
On a side note, I will be updating my Banshee page soon with some updated Windows 95/98, Windows NT 4.0, and Windows 2000 drivers. The drivers released by 3dfx recently were CRAP. I will be making new drivers for Windows 95, 98, and 2000 with updated Glide and OpenGL files from the recent reference driver release - but with older 2D drivers that are more stable than what 3dfx included in its newest reference drivers. The NT4 drivers I should have up will be pretty much unchanged from 3dfx's NT4 reference drivers, but will have my updated INF file in them to improve stability (several people get scrambled or other messed up graphics in NT4 with 3dfx's reference drivers, including me).
No ETA as to when the new drivers will be up.
