Quick question - I couldn't find a google explanation.
Why does the default SB Pro compatibility for Aureal Vortex2 boards use two DMA channels? The default is both 1 and 3 in Windows 98. If I override the default settings and use Basic Configuration 0004 (in my case), I can get it to just use IRQ 7 and DMA 1, with no second DMA channel.
Everything works, so I don't know if I am losing anything by doing this, but I just wanted to know why the SQ2500 board defaults to using two DMA channels.
