Works either way.

You can use any setting for the DMA channel except for 0, and any
IRQ number that you can strap the board for. Note that when you fiddle with
these there is one strap that tells the board what to use, and there is a
second strap that tells the board what to tell the CPU that it is using, and
if you have the board incorrectly strapped these can be different.
Finally, you can use I/O address 0x330 or 0x334. I could add more, but
I do not like the idea of probing a whole bunch of memory addresses when we are
not even sure if the board is in the system or not.
