[SOLVED] how to add driver during the boot

DBabo · 03-30-2015, 08:51 PM

Gents,
i wonder how can i load a driver during the system boot (fedora 21)?

Current situation:
a. dell latitude e6400
b. built-in Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)

during the boot network (wifi) won't come up and i manually have to :

Code:

export FIRMWARE_INSTALL_DIR="/lib/firmware"
b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o

modprobe -r b43
modprobe b43

after that wifi comes up and life is great... until next reboot.
Appreciate your guidance

You can put the following in a file say wifi.sh:

Code:

export FIRMWARE_INSTALL_DIR="/lib/firmware"
b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" broadcom-wl-5.100.138/linux/wl_apsta.o

modprobe -r b43
modprobe b43

And then put wifi.sh in /etc/rc.d/rc.local

Make sure that /etc/rc.d/rc.local has got execute permission.

thats a good idea. thank you.
yet i thought there maybe a "better" way to accomplish the same ?

Another way to do it is to recompile the kernel with the driver so that the driver becomes part of kernel itself. More work, so adding it to /etc/rc.d/rc.local would be an easier way to achieve the same.

plus - won't have to recompile after every kernel update... (which is often)..
i think you convinced me to use your solution

thank you
