how to load a kernel module at boot time

yugandhar · 08-19-2006, 07:22 AM

Hi all,
In my project i have written one driver on top of the parallel port.Now i want to Load my driver which is a kernel module to load into the kernel at boot time whenever i starts the system.
I am using Fedora Core 3 of 2.6 kernel. I have gone through some articles for loading a kernel module at boot time what they are saying is that add modules to /etc/modules and aliases in the /etc/module.conf but these two files are not there in my system. So please help me in this. I also want to load the application daemon which initializes the driver which will also wants to start at boot time.
I am greatful if you explain how to do it with a sample shell script example for both daemon application and driver module.

Reading old articles??????

Try /etc/modprobe.conf you can also add the module loading to someplace like /etc/rc.d/rc.local if need be.

Code:

$ cat /etc/rc.d/rc.local
#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.

touch /var/lock/subsys/local

# I2C adapter drivers
modprobe i2c-sis96x
# I2C chip drivers
# modprobe eeprom
# sleep 2 # optional
/usr/bin/sensors -s # recommended

# My system tweaks

/usr/sbin/ntpdate -u 128.10.252.7

/sbin/modprobe evdev
/sbin/modprobe -r snd_intel8x0m

Added a couple of examples (above) starting at the comment; # My system tweaks

Code:

$ cat /etc/modprobe.conf
alias net-pf-10 off
alias eth0 sis900
alias eth1 orinoco_cs
alias eth2 prism54
# I2C module options
alias char-major-89 i2c-dev
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0

install snd-intel8x0 /sbin/modprobe --ignore-install snd-intel8x0 && /usr/sbin/alsactl restore >/dev/null 2>&1 || :

remove snd-intel8x0 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
