Chapter 7

FreeBSD Driver

Installation

This chapter describes the installation of the FreeBSD

driver and

consists of the following section:

• Section 7.1, “Upgrading the Driver on an Existing FreeBSD System”

7.1 Upgrading the Driver on an Existing FreeBSD System

When the FreeBSD operating system is already installed, the kernel

image has to be updated on the new driver module. Perform the following

steps to install the FreeBSD driver.

Step 1. Make sure that the kernel source has been installed on the

system. If the kernel source has been installed, the

/usr/src/sys directory exists.

Step 2. Move to the arch/conf directory and copy the GENERIC

configuration file to a new file. The new file will be the kernel

configuration file. Here is an example:

# cd /usr/src/sys/i386/conf

# cp GENERIC MYKERNEL

Step 3. Copy the zip file (mfi.zip) under the path /usr/src/sys/dev.

Before you proceed to the next step, make sure that the

directory with name “mfi” does not exist under the path

/usr/src/sys/dev/. If a directory with the name “mfi” already

exists, move it to a different folder. For example, type the

following command: mv /usr/src/sys/dev/mfi

/root/mfibackup.

Step 4. Go to the directory /usr/src/sys/dev and run the following

command to unzip the source:

tar –x –f mfi.zip
