Yo Craig Hart,
 CH> You simply try all DMA channels and IRQ's until you find the
 CH> one that works.
 CH> some psuedo code:
 CH> for dma=0 to 7 do for irq = 0 to 15 do play a 1 byte sample
 CH> using DMA so that an irq is triggered. did our ISR go off? no : try
 CH> next values yes : OK we have the settings!! end.
Don't I have to know the port address for that ?
Let's say you don't know which port the SB uses... Can I TRY to play a
(one byte) sample on all the IRQ's,DMA's and PORTs no matter what device
is using them ? What if there is a videocard or something using them ?
How will it react ?
