6. Reboot the system to use the new kernel.
NOTE: Add this line next to the line that has:
dev/mfi/mfi_cam.c optional mfi.
7. Copy the zip file (mfi.zip) to the /usr/src/sys/dev directory.
Before you proceed to the next step, make sure that the mfi directory does not
exist in the /usr/src/sys/dev/ directory. If the mfi directory already exists,
move the directory to a different folder. For example:
mv /usr/src/sys/dev/mfi /root/mfibackup.
8. Go to the directory /usr/src/sys/dev and run the following command to
unzip the source:
tar –x –f mfi.zip
9. Go to the directory /usr/src/sys/dev/mfi and run the following command
to compile the driver:
make clean all
10. Run the following command to load the compiled driver:
Kldload ./mfi.ko
7.2 Limitations The FreeBSD operating system does not support supplying Driver Update Disks (DUDs)
at installation time. The kernel that comes with the installation CD has the driver
statically linked in it but not as a module. Hence, it is not possible to override the driver
binary that is part of the kernel with the new driver module.
