The rumours are wrong.

Yes.
Method 1: boot dos first and run ctcm.
Method 2: use the pnp patch to configure the card (my -current-fied)
version of this attached. Apply in /usr/src/sys. You'll have to edit
pnp.c to insert your card's settings. As you can see, I'm using 0x220,
0x300 (usually 0x330, but I have an aha1542 at that address), 0x388,
and dma 1 7 (usually 5), irq 5.
Regards,
David
