FreeBSD Driver Installation

Updating Drivers in the FreeBSD System

Proceed to the /usr/src/sys/modules/ directory and perform the following steps.

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 module, type the following command and press Enter:

# mv /usr/src/sys/modules/mfi /root/mfi_module.backup



To move the mrsas driver module, type the following command and press Enter:

# mv /usr/src/sys/modules/mrsas /root/mrsas_module.backup

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/modules/mfi

To make sure the mrsas directory exists, type the following command and press Enter:

# mkdir /usr/src/sys/modules/mrsas

Perform the following steps:

Unpack the compressed driver source file (mfi.tgz for the mfi driver and mrsas.tgz for the mrsas driver).

Move the *.c and *.h files to /usr/src/sys/dev/driver_name (the driver name is mfi for the mfi
driver and mrsas for the mrsas driver).

Move the Makefile to the /usr/src/sys/modules/driver_name (the driver name is mfi for the mfi
driver and mrsas for the mrsas driver).



For example, to unpack the compressed driver source file and move the Makefile for the mfi driver, enter
the following commands and press Enter:

# cd /usr/src/sys/dev

# tar -xf mfi.tgz

# mv mfi/Makefile /usr/src/sys/modules/mfi/



To unpack the compressed driver source file and move the Makefile for the mrsas driver, enter the
following commands and press Enter:

# cd /usr/src/sys/dev

# tar -xf mrsas.tgz

# mv mrsas/Makefile /usr/src/sys/modules/mrsas/

Go to /usr/src/sys/i386/conf if you are running a 32-bit version of the FreeBSD OS, or



/usr/src/sys/amd64/conf

if you are running a 64-bit version of the FreeBSD OS, and perform the

following steps:

Copy the GENERIC configuration file to another filename. For example:

# cp GENERIC MYKERNEL

Open your current configuration file (GENERIC, MYKERNEL, SMP, or PAE, or custom configuration), with vi
or another editor. For example:

# vi MYKERNEL
