One thing to remember... 2000 was never designed with gaming interests in mind. Now I'm not saying you can't treak it, but don't expect 100% compatibility with a lot of games. 2000 was designed as a "business" operating system and was so successful they decided to base XP off of 2000 instead of 98 (Remember what a nightmare ME was?)
Actually now that I think of it, I liked ME... I think the biggest problems it had was people loading 98 drivers into it, as ME driver supports wasn't exactly great... but I think that's for a different discussion.
I remember once forcing 95 modem drivers onto a 2000 system... and was actually shocked that it worked.. flawlessly at that.. without a bluescreen.
There there's my father in law... he bought one of the cellphones with a camera.. then bought a USB bluetooth adapter so he could download his pictures wirelessly... never could get it to work. I went over there and realized he had no USB drivers installed... I installed the appropriate drivers for him (98SE), still nogo. After screwing with it four hours... finally took a potshot and installed win95v2 drivers on it.. and it worked flawlessly... strange happenings sometimes, I swear!
The whole time he was swearing up and down that it wouldn't work, because the box for the bluetooth said "2000/XP" on it and I told him to get it anyway because the salesloser at best buy was pushing one that was $100....
Ok I've strayed off topic here... good luck to you!
