DESCRIPTION    [Toc]    [Back]

     The gusc bridge driver allows the generic audio drivers including pcm(4)
     to attach to the following ISA sound cards:

     +o	 Gravis UltraSound PnP

     +o	 Gravis UltraSound MAX

     The value of flags specifies the secondary DMA channel.  If the secondary
     DMA channel is C, set the flags to (C | 0x10). For a sound card without
     the secondary DMA channel, the flags should be set to zero.
