# For more information read the handbook part System Administration -> 
# Configuring the FreeBSD Kernel -> The Configuration File. 
# The handbook is available in /usr/share/doc/handbook or online as
# latest version from the FreeBSD World Wide Web server

#
# An exhaustive list of options and more detailed explanations of the 
# device lines is present in the ./LINT configuration file. If you are 
# in doubt as to the purpose or necessity of a line, check first in LINT.
