1.  Run DOS 'diagnose' (or isapnptools, or Windows) to determine
io (default io=0x220)
irq (default irq=5)
low dma (default dma=1)
high dma (default dma16=5)

2.  If there are no available IRQ or DMA settings for DOS diagnose, use 
Windows or isapnptools to change the settings to something that is free. 
On one of my computers the parport was broken and the card I put in to 
replace it was tying up both IRQ 5 and DMA 0 and 1 so I had to reset the 
card to IRQ 7 and DMA 3 and 5.

3.  When insmodding sb, if you discovered that you can play wav but not 
mp3 files, you have a conflict with the HIGH dma setting.  Christof's BL 
sound package, in its sample sb-on file, specifies ONLY the low dma 
setting.

What worked for me, on a card with standard settings (and no ISA parport 
card in teh computer), was

insmod sb io=0x220 irq=5 dma=1 dma16=5

On the computer with the paport card:
insmod sb io=0x220 irq=7 dma=3 dma16=5


The problem with high DMA occurred on my ASUS (both boards)Super Socket 7 
K6 (300 and 300MHz) and on my PIII (Tyan?) board, both of which appear to 
use DMA 5 for something else.  These three boards have USB, and Windows 
was using one IRQ for a USB to PCI something-or-other.


/proc/dma does not reveal what is using DMA 5 (unless you insmod the sb 
card, which then uses it).

The problem has something to do with writing data to /dev/dsp, which uses 
DMA 5, whereas playing wav files does not.


The ASUS boards work with the Mplayer second version for PI but not with 
the first version for PII.   The faster board works with the PII version 
but not the PI version.

I changed the subject line so people outside this list can find the 
information.


Christof, please add dma16=5 to your package on the insmod sb line.
