Loading kernel modules at boot

burk · 04-20-2002, 09:16 AM

I have a K7SEM motherboard with the pctel amr modem, running Mandrake 8.1. I found a driver for the modem on the web. It has an install script that creates and loads 2 modules, pctel.o and ptserial.o. I can load the modules manually using insmod, but I would like to have them load at boot. Where do I need to put the modules? Which init. file do I need to edit and what are the commands? Thanks.

find out "rc.local" # find /etc -name rc.local

edit it as root

append this line:
modprobe pctel.o ptserial.o

Notes:
-under slackware, "rc.local" is located on /etc/rc.d/
I don't know what's about redhat or mandrake,thus I've suggested to use "find".

good luck

Under RH and Mandy it's under the same location /etc/rc.d/rc.local

I inserted the following lines in the /etc/rc.d/rc.local file at the end just before the final line (touch /var/lock/subsys/local).

modprobe /home/dale/modem driver/lib/pctel.o
modprobe /home/dale/modem driver/lib/ptserial.o

I get an error message that has something to do with permissions, I think. It flies by pretty fast during boot, and I'm not sure which log file to take a look at.

Do "dmesg" right after login to see the boot messages.
If you did a make install on the modem driver then the modules should be in /lib/modules/<kernel-version> and can be loaded with "modprobe pctel" and "modprobe ptserial", you don't use the .o in the command when loading a module, also you should try adding the modules to /etc/modules.conf.

The install script just does make, then installs using insmod. I guess I need to do some reading on kernel modules. Thanks

If you add the following lines to your install script
the modules will load each time you boot up.

As root add this:
----------------------------------------
mkdir /lib/modules/`uname -r`/misc
cp lib/*.o /lib/modules/`uname -r`/misc

echo "insmod pctel" >> /etc/rc.d/rc.local
echo "insmod ptserial" >> /etc/rc.d/rclocal

------------------------------------------------

Let me know if it works for you.
This driver also works in Mdk 8.2

Thanks Egort. I had already copied the files to the directory and edited my rc.local. Glad to hear the drivers work in 8.2, I've been thinking about upgrading.
