31.Sh NAME
32.Nm snd_sbc
33.Nd Creative Sound Blaster ISA and compatible bridge device driver
34.Sh SYNOPSIS
35To compile this driver into the kernel, place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device sound"
39.Cd "device snd_sbc"
40.Ed
41.Pp
42Alternatively, to load the driver as a module at boot time, place the
43following line in
44.Xr loader.conf 5 :
45.Bd -literal -offset indent
46snd_sbc_load="YES"
47.Ed
48.Pp
49Non-PnP cards require the following lines in
50.Xr device.hints 5 :
51.Bd -literal -offset indent
52hint.sbc.0.at="isa"
53hint.sbc.0.port="0x220"
54hint.sbc.0.irq="5"
55hint.sbc.0.drq="1"
56hint.sbc.0.flags="0x15"
57.Ed
58.Sh DESCRIPTION
59The
60.Nm
61bridge driver allows the generic audio driver
62.Xr sound 4
63to attach to Creative Sound Blaster ISA compatible audio cards.
64.Pp
65The value of flags specifies the secondary DMA channel.
66If the secondary
67DMA channel is C, set the flags to (C | 0x10).
68For a sound card without the
69secondary DMA channel, the flags should be set to zero.
