This could propably help. SB16 has software configurable IRQ and DMA
numbers. However there are some problems with it with it with oldest SB16
models. The IRQ selection seem to be locked after the setup register has
been written first time. If it has been configured to use another IRQ
under DOS, Linux may fail changing the register properly.

In the oldest SB16 models there is a jumper for setting the IRQ. I don't
know how the software IRQ setup works with these cards. Possibly the
software setup is just ignored and the card uses always the jumpered value.
