quick questions about modules
 

how exactly does /etc/rc.d/rc.modules fit into things? when it's run at startup it consults /lib/modules/$REALEASE/modules.dep (that's what it says anyway), and loads any modules listed there? is that correct?

i'm asking because i'm trying to clean out my lsmod list. i've got some stuff i don't need, like agpgart for instance. i found that in rc.modules and commented out the line, so that's ok. but lsmod lists a bunch of OSS modules, and i'm pretty sure i don't need those. they're not listed in rc.modules though...in fact, the only uncommented line is apm. so i can't clean any more out by editing rc.modules.

now i've looked at /lib/modules/2.4.26/modules.dep and it's a very long file. there are a lot of modules listed that i don't recognize. as i understand it, modules.dep is created when you compile your kernel (make modules, make modules install), so i'm not even sure i should be editing it in the first place (i haven't touched it yet). is that the way to remove unwanted modules? or do i need to generate a new modules.dep file by recompiling the kernel?

What does lsmod look like? You shouldn't have any oss modules loaded for any other sound device with the exception of the card you have.
good luck.

hi there,

i think those OSS modules are loaded by hotplug.
if you put them on the blacklist ( /etc/hotplug/blacklist : just add the names to the list )
then they won't load anymore on boot.

root@lightstar $ lsmod

so i removed ide-scsi and agpgart from rc.modules, i don't know what uhci is, or usbstorage, but it looks like those two and usbcore are somehow all connected. i have a usb jumpdrive which i'd like to keep using, so i'll probably leave them until i can verify exactly what they do. you can see though what i meant about sound modules. they're not all OSS like i thought they were, but easily 3/4 of all those entries are sound modules....i must be able to get rid of some of those, right?

No those are your alsa modules, and I'd advise leaving them be unless you would like to wreak havoc on your sound. :D
good luck.

all of them? wow!

Alsa uses different modules for different devices and features. I'm not 100% certain that you need all of them, but, if all of your sound functions are working I'd leave them alone. On the other hand, if you don't break anything, you won't know how to fix anything. :D
good luck.

hehe, alright thanks man. i appreciate your help!

Glad to be of service sir. Take care.
good luck.
