Reboot your system.
When the system reboots, the new kernel driver module will load
automatically.
Installing the 3ware Kernel Driver Module on a FreeBSD
System that Boots from a Device on the Motherboard
Use the steps in this section if FreeBSD is installed on a boot drive attached to
the motherboard ATA controller, and you will be using the unit on your 3ware
RAID controller for secondary storage.
When you use the controller for secondary storage, you do not need to install
the kernel driver module, however you may want to update the kernel with it.
Note:
If you have more than 4 GBytes of system memory, you will need to use the
PAE kernel. The FreeBSD PAE kernel has a bug that requires the 3ware driver to
be statically compiled. Do not dynamically load the kernel driver module (e.g.
kldload twa.ko
); doing so will cause the kernel to panic.
