Not until after I spent a few hours trying to outguess the computer about 
IRQs and DMAs.  It was more educational that way, of course.

They did, thanks.

DOS ctcm offered some configurations without mpu ios at all.

If I don't need FM synthesis why would I want to leave in the mpu io?

This looks like the 'configurations' offered by DOS ctcm. - Choose
one set and then modify as needed.

I have never even SEEN an MPU device - what do they look like?

In DOS I have a program that I can use to turn it on and off.  I think it 
is some 3D effect that your Vibra16 does not have.  It is off by default 
in DOS and midis play just fine anyway.  I wonder how I would turn it on 
in linux and use it.  Reverb?  I have an Audio Excel with 3D.

It seems to work (no error messages) but now drvmidi no longer plays midi 
music - just silence like before I got this working.  It might not be a 
good idea to initialize the card both in DOS and with isapnp.  I will try 
isapnp after bypassing system files some time.  I rmmod'ed sb and 
awe_wave, insmodded sb with the new settings, and then insmod awe_wave 
said SB32 not detected (just like before I initialized with DOS) so maybe 
two rights made a wrong.

I can try isapnp to determine the settings for the ne ethernet card.
