+.Sh SEE ALSO
+.Xr sound 4
+.Sh HISTORY
+The
+.Nm
+device driver first appeared in
+.Fx 4.2 .
+.Sh BUGS
+The Forte Media FM801 chipset is a sort of PCI bridge, not an actual
+sound controller, making it possible to have soundless support.
+One problem is that both chipsets, with and without sound support, use the
+same PCI ID.
+This makes it impossible to determine which one is installed.
