Chapter 4. Driver Installation
Compiling and Loading the driver as a Module
If you want to compile the driver and load it as a module without rebuilding
the kernel, follow these steps.
1 Disconnect all drives in the system, except the CD or DVD and the ones
connected to the 9550SX controller.
2 Create the RAID units on the 9550SX using 3BM (BIOS)
3 Unpack twa.tgz and copy (*.c and *.h) files to
Makefile to
4 cd /sys/modules/twa
make
5 Comment out the entry
usr/src/sys/i386/conf
6 Rebuild the kernel and reboot your system.
7 Load the kernel driver module from
kldload twa.ko
Upgrading the Driver for 9500S Controllers
The FreeBSD 5.4 kernel has native support for 3ware 9500S RAID
controllers; the driver is built in.
If you want to upgrade to the latest driver, you can do so and rebuild the
kernel. Follow the instructions under "To update the kernel with new driver
source" on page 52.
