Is there a way to determine the PCI clock speed for a given system. I
have a board that has a timer which is incremented once per PCI clock.
To determine the PCI clock speed, I calculated the number of ticks in
this timer over a period of 5 seconds which was clocked by the PC timer
and then did a divide to determine the frequency. If I didn't have this
timer, I would not have been able to determine this frequency.
In addition, if I didn't have this timer, I probably wouldn't need to
know the PCI clock rate. But that's a different subject. It seems
that there should be a system call in the PCI bios that shall give this
