I recall setting those in bios years ago, but I think its doable in the
kernel as well (driver? maybe)
However you should read at least the manual to your card [3].
IT looks to me both CS4236B and S16 reister to the 8bit ISA while the other
with IRQ9 must be 16bit - thus getting IRQ>8
look at [1] to see which IRQ you could probably use and into [3] for
detailed spec on ISA configuration.
