38 Non-PnP cards require the following lines in
39 .Pa /boot/device.hints :
40 .Cd hint.sbc.0.at="isa"

48 bridge driver allows the generic audio drivers including
50 to attach to Creative Sound Blaster ISA compatible audio cards.
52 The value of flags specifies the secondary DMA channel.
54 DMA channel is C, set the flags to (C | 0x10).
55 For a sound card without the
56 secondary DMA channel, the flags should be set to zero.
60 driver supports the following sound cards:
98 .It sb_dspwr(XX) timed out.
99 A command to the DSP has timed out.
100 Check the I/O port configuration.
101 .It bad irq XX (5/7/9/10 valid)
102 The IRQ given to the driver is not valid.
