Module snd-sc6000
-----------------
Module for Gallant SC-6000 soundcard.
Module for Gallant SC-6000 soundcard and later models: SC-6600
and SC-7000.
port - Port # (0x220 or 0x240)
mss_port - MSS Port # (0x530 or 0xe80)
irq - IRQ # (5,7,9,10,11)
mpu_irq - MPU-401 IRQ # (5,7,9,10) ,0 - no MPU-401 irq
dma - DMA # (1,3,0)
joystick - Enable gameport - 0 = disable (default), 1 = enable
This module supports multiple cards.
