Updating the Firmware and Driver
www.3ware.com 201
To compile the driver as a module
1 Boot to FreeBSD.
2 Download and extract the driver, as described under “Downloading the
Driver and Firmware” on page 181.
3 Unpack twa.tgz. Then copy the *.c and *.h files to
/sys/dev/twa and the Makefile to /sys/modules/twa .
4 Build the twa.ko module
cd /sys/modules/twa
make
The twa.ko module is created in /sys/modules/twa
To load the driver as a module
1 In the current configuration file under /usr/src/sys/i386/conf or
/usr/src/sys/amd64/conf comment out the entry: " Device twa #
3ware 9000 series ". This will unlink the old driver once you rebuild
the kernel.
2 Rebuild the kernel.
Run command config <config_name> specifying your configuration
file: (GENERIC, SMP, PAE, or your custom config), followed by:
cd ../compile/< config_name >
make clean
make cleandepend
make depend
make
make install
3 Reboot to FreeBSD.
4 Load the kernel driver module from /sys/modules/twa
cd /sys/modules/twa
kldload ./twa.ko
5 If you wish to load the driver automatically every time the system is
rebooted,
add the line ' twa_load="YES" ' to the file
/boot/loader.conf
