One could just change the #define, but a more "elegant" method is to open /dev/kmem and burrow through the namelist to find how fast the timer really ticks on that machine. I'll spare you the details of figuring out how to do this. When I get that far (if ever), I'll just steal the appropriate code from "gprof" which figures the clock rate in just this manner. -- Ray Essick, University of Illinois -- {ihnp4,convex,pur-ee}!uiucdcs!essick essick%uiuc@csnet-relay.arpa
