Hello,


I have experienced some kind of problem in a serial
board that has "compatible" 16550 chips for sio.
The problem resides that the sio driver expect to see 
a real 16550 or 8250 chip, during the startup test,
in the attach routine, and one of the tests fail.

Solution: 
	Modify the attach routine in sio.c (/usr/src/sys/i386/isa)
	there is a piece of code that makes 4 tests, recompile the
	code by doing a "printf" of the counter, and see where it
	stops, and ignore the situation.


Sergio de Almeida Lenzi.
