[Newbie]Help with 3dfx Voodoo5

[David Shickle]

Hi, I've just installed on a new machine with a Voodoo5 setup. When I run Xfree86 -configure, it does it thing.   All I get out of the config is 60khz refresh and I cannot figure out how to get it to something more resonable like 85khz   Can anyone offer simple advice on what to change in the config files   thanks   David
