How do you load instructions at boot time?

[williewang]

please help me! I'm a complete newb at this but i'm learning new things at a phenomenal rate thanks to you guys! :]

ok. at boot time, i want to load my acer_acpi module which i usually load at terminal by using modprobe acer_acpi. Can anyone tell me how to do this?

Also I want to give a couple of terminal instructions at boot time too - eg.
echo "enabled: 1" > /proc/acpi/acer/wireless
ifdown wlan0 daemon
service driverloader reload
dldr_wpa_supplicant -B -c /etc/driverloader/dldr_wpa_supplicant.conf -i wlan0 daemon
ifup wlan0 daemon

i've been told i have to edit the rc.local file, but this file doesn't seem to exist anywhere on my system. does anyone know of a file that i can edit and add these lines to to make them load at boot-time?

i really really need to know this to start my wireless workiing... please please please help all you linux gurus!
