5. 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:
a. Copy the GENERIC configuration file to another file name. For example:
# cp GENERIC MYKERNEL
b. Open your current configuration file ( GENERIC, MYKERNEL, SMP, or PAE, or custom configuration), with vi
or another editor. For example:
 For a dynamically loadable module, comment out the following lines by typing # at the start of the line:
For the mrsas driver, comment out the following line by typing # at the start of the line, if it exists:
#device mfi # LSI MegaRAID SAS
