Boot says ec0 on IRQ9. 3c503 does not support IRQ9. irq9 is really irq2, that is to say: The card thinks it is on irq2 but the motherboard thinks the card is on irq9. It is like this because of the way the two irq controllers are daisy-chained together. By your description, the card seems to be detected alright so you must have the card on irq2. Maybe you have to select the right DMA channel on the card for it to work. I have not even got this far with the 3c503 so I have a question of my own: How do you set the card to irq2 ? I tried the DOS 3c503.exe diagnostics program to set the irq level, but it resets the irq afterwards. Someone told me that it doesn't keep the value between powerdown resets either, so that would not be much use anyway. So, how is it possible to set the correct IRQ and DMA values on the card before the card is probed (it is one of those EtherLink II things). -- Adam D. (adam@veda.is)
