   --- device     cbb          # cardbus (yenta) bridg
   +++ #device     cbb         # cardbus (yenta) bridg
   

3. Add the following line to the file /usr/src/sys/conf/files.

   mv /usr/src/sys/dev/mfi /root/mfibackup
   cd ~
   git clone git://github.com/linpc/sas9240-freebsd-mfi-driver.git .
   cp -r sas9240-freebsd-mfi-driver/9.0/mfi /usr/src/sys/dev/mfi
