FreeBSD Driver Installation
Updating Drivers in the FreeBSD System
5. Proceed with the installation on a drive attached to the motherboard.
Make sure you install the full the FreeBSD OS source.
6. After the OS installation, follow the instructions for driver installation in Section 6.6.1, Updating the Kernel with
the New Driver Source (for a statically linked module), or in Section 6.6.2, Compiling and Loading the Driver as a
Module by using kldload (Dynamically Loadable Module) .
6.6 Updating Drivers in the FreeBSD System
You can update drivers either from source files or with driver modules. By using source files, you can compile drivers
into the kernel, or you can create modules for versions of the FreeBSD OS for which LSI does not supply modules.
This section includes these topics:
 Updating the kernel with the new driver source
 Compiling and loading the driver as a module using kldload (dynamically loadable module)
 Updating the MegaRAID kernel driver module in the FreeBSD OS
6.6.1 Updating the Kernel with the New Driver Source
Use this procedure to update your kernel from driver source files for both a dynamically loadable module and a
statically linked module. To obtain the source files, see
Section 6.2, Obtaining LSI FreeBSD Drivers .
Perform the following steps to update your kernel with the driver source files:
1. Make sure that the kernel source has been installed on the system.
The kernel sources are in the /usr/src/sys directory.
2. Go to the /usr/src/sys/dev/ directory and perform the following steps.
a. Check to see whether a directory with the driver name already exists. If a directory already exists, move it to a
different folder.
 For example, to move the mfi driver, type the following command and press Enter:
# mv /usr/src/sys/dev/mfi /root/mfi.backup
 To move the mrsas driver, type the following command and press Enter:
# mv /usr/src/sys/dev/mrsas /root/mrsas.backup
b. Make sure the directory exists.
 For example, to make sure the mfi directory exists, type the following command and press Enter:
# mkdir /usr/src/sys/dev/mfi
 To make sure the mrsas directory exists, type the following command and press Enter:
# mkdir /usr/src/sys/dev/mrsas
