The PSS driver enables MSS and MPU401 modes of the card. SB +is not enabled since it doesn't work concurrently with MSS. + +If you build this driver as a module then the driver takes the following +parameters + +pss_io. The I/O base the PSS card is configured at (normally 0x220 + or 0x240) + +mss_io The base address of the Microsoft Sound System interface. + This is normally 0x530, but may be 0x604 or other addresses. + +mss_irq The interrupt assigned to the Microsoft Sound System + emulation. IRQ's 3,5,7,9,10,11 and 12 are available. If you + get IRQ errors be sure to check the interrupt is set to + "ISA/Legacy" in the BIOS on modern machines. + +mss_dma The DMA channel used by the Microsoft Sound System. + This can be 0, 1, or 3. DMA 0 is not available on older + machines and will cause a crash on them. + +mpu_io The MPU emulation base address. This sets the base of the + synthesizer. It is typically 0x330 but can be altered. + +mpu_irq The interrupt to use for the synthesizer. It must differ + from the IRQ used by the Microsoft Sound System port. + + +The mpu_io/mpu_irq fields are optional. If they are not specified the +synthesizer parts are not configured. + +/*(DEBLOBBED)*/
