Lahaie Changed probing / attach code order - * Scott Murray Added mixer support (Dec 03, 1998) - * Scott Murray Changed detection code to be more forgiving, - * added force option as last resort, - * fixed ioctl return values. (Dec 30, 1998) - * Scott Murray Simpler detection code should work all the time now - * (with thanks to Ben Hutchings for the heuristic), - * removed now unnecessary force option.

(Dec 6, 2000) - * Scott Murray Inspired by a patch by Peter Englmaier, and based on - * what ALSA does, added initialization code for the - * default DMA and IRQ settings. (Dec 6, 2000) - * Scott Murray Added some more checks to the card detection code, - * based on what ALSA does. (Dec 12, 2000) - * Scott Murray Inspired by similar patches from John Fremlin, - * Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4 - * ISA PnP API support, mainly based on bits from - * sb_card.c and awe_wave.c.
