Bryce Denney d12a76d30b - Applied patch: pit-panic. The 82c54 model (pit.cc) implements timer modes 0, 2, and 3 in its handler functions, without caring which timer number is involved. However, the I/O write code that sets the mode is inconsistent. Timer 0 can be set to modes 0,2,3 only. Timer 1 can be set to mode 2 only. Timer 2 can be set to mode 2,3 only. From a quick reading of an 8254 datasheet, I can't see any reason to restrict which timer can be in which mode, so I think it's correct to allow ALL timers to go into ALL modes that are implemented.	2001-04-10 02:14:37 +00:00
