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

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?).
