I have small problem:
XaoS needs to quite exactly time one part of program. (Uses it to calculate
framerate: time*5 so for framerate 30 I need to know time in precisity 1/150sec.
) higher precisity is better.
Gettimeofday(I using in unix) is not exact enought (1/18.2sec...4 or inf frames
per second) 

What is the best way to time this? Only I know about is to attach timer, set
it to higher rate and make some my own counter. Can some send me code for this?
Since I am lazy to study all irq attaching stuff under dpmi. Last time I did
this is about 5 years ago in assembly.
