That variant of the chip must be used with the 55.Xr wss 4 56driver. The 57.Nm 58driver will not attach to such chips. 59.Sh SEE ALSO 60.Xr audio 4 , 61.Xr intro 4 , 62.Xr midi 4 , 63.Xr pci 4 , 64.Xr wss 4 65.Sh HISTORY 66The 67.Nm 68device driver appeared in 69.Nx 1.5.1 . 70.Sh BUGS 71The MagicMedia 256 series is not well-documented. 72.Pp 73No MIDI or FM synthesizer capability is provided with the MagicMedia 256 74in AC'97 mode.
