3692 Problems: It seems that Trident chips generates interrupts more than
3693 one time in special cases. The spurious interrupts are
3694 detected via sample timer (T4D_STIMER) and computing
3695 corresponding delta value. The limits are detected with
3696 the method try & fail so it is possible that it won't
3697 work on all computers. [jaroslav]
