As for the IRQ, I have no clue. This is the only documentation I could > find which seemed relevent. The IRQs should be 4 and 3, respectively, assuming they're using industry standard settings. Most likely, the 16550 UART emulation on the I/O controller isn't quite up to snuff. YOu can check this by typing `-v' at the Boot: prompt and checking the output of the probe test for the sio devices. If they're like what I've seen from this error, two of the tests will fail for each one.
