Hi everyone.

I need to have an interrupt at shorter intervals than the timer
chip is programmed to do.

"Undocumented Windows" explains how to set a synchronous callback.

From what I know at this points it seems I need a timer device driver
that will reprogram the timer chip with the frequency I want.

The multimedia extensions available with 3.1 are supposed to do this for
me. Yes ?

I am hesitant to manually reprogram the chip because I dont know how this would
fare with the rest of windows. Unexplained crashes are the least thing I want.

Has anyone done anything similar ?

Thanks
NN
