FreeBSD Driver Installation

Updating Drivers in the FreeBSD System

To compile the kernel, go to the /usr/src directory, type the following commands if your current
configuration is MYKERNEL, and press Enter.

# cd /usr/src

# make buildkernel KERNCONF=MYKERNEL

To install the new kernel, type the following commands if your current configuration is MYKERNEL, and
press Enter.

# make installkernel KERNCONF=MYKERNEL

The new kernel is copied to the /boot/kernel directory.

The old kernel is moved to the /boot/kernel.old directory.

Reboot your system to use the new kernel.

When the system reboots, the new kernel driver module loads automatically.

6.6.2

Compiling and Loading the Driver as a Module by using kldload (Dynamically Loadable
Module)

To use a driver module in case LSI does not supply a driver module for your version of the FreeBSD OS, use the
procedures in this section. If you want to install only an LSI-supplied module, see

Section 6.6.3, Updating the

MegaRAID Kernel Driver Module in the FreeBSD OS

NOTE

You can use kldload to load the driver as a module only if your boot
drive is attached to the mother board and is not managed by the
MegaRAID controller.

Perform the following steps to compile the driver as a module:

Boot to the FreeBSD OS.

Obtain driver source files; see

Section 6.2, Obtaining LSI FreeBSD Drivers

Make sure your kernel is prepared for the dynamically loadable module described in

Section 6.6.1, Updating the

Kernel with the New Driver Source

To build the driver module, type the following command, depending on which driver you use, and press Enter.

For the mfi driver, type the following commands and press Enter.

# cd /usr/src/sys/modules/mfi

# make
