Setting the refresh rate for ATI Radeon in Win2k

[Kishkumen]

I have an ATI Radeon 64MB. Does anybody know how to set the refresh rates for games like Quake 3 when run under Windows 2000? Every time I try to run Quake it goes to 60Hz instead of the 85Hz my Hitachi CM751 19" can usually do. With my GeForce 2 there was a nice little tool called NVidia Refresh Rate fix that adjusted the values in some .inf file I guess. Does anything like this exist for the Radeon? If not can I adjust it manually? Thanks for any help.
