How would I automate this, perhaps by putting all the insmods in rc except 
for the mad16 itself?  I am about to set up a Basiclinux computer for the 
high-school-age son of a friend who views it as a big upgrade from Redhat 
6.2 (which he figured out how to get to boot into CLI).  The opti929 card 
has a nice volume dial and a speaker/line jumper so he can use headphones 
until he gets speakers with volume controls.  He likes to listen to MIDI 
files - my next challenge (non-AWE midi).  He is willing to switch over 
completely as long as he can use the programs he compiled for Redhat 6.2 - 
is that the same library as BL3?  I was going to put on both 2 and 3, with 
chroot scripts.  He is interested in the games, and Abiword, and sc (which 
he compiled for Redhat), and RPM (I told him rpm2tgz would help) and 
Gnumeric - does that require GNOME?  He also wants a parport zip drive so 
I might copy him over the zip drive BL3 as well.

That is essentially what I have had to do to get this to work.
But if I separate the steps - all but mad16 in rc, and the mad16 line when 
needed, will that also work?  insmod mad16 could be in a script called 
'sound'.

Silly program then, since a lot of sound cards seem to use io=0x530 or 534 
in WSS mode.

Why does ALSA not work with the same module for 929 and 931?
I have five 929s and had two more so they must be common.

I have to get midi working in linux without AWE now.  At least I have two 
types of card to experiment on.

Are the BL3 games statically compiled (will they work in BL2?).
