# This directive is mandatory; it defines the architecture to be
# configured for; in this case, the 386 family.  You must also specify
# at least one CPU (the one you intend to run on); deleting the
# specification for CPUs you don't need to use may make parts of the
# system run faster

# DEBUGGING OPTIONS

#
# This line enables the kernel debugger, DDB, and the line following

#
# The DIAGNOSTIC option is used in a number of source files to enable

# NETWORKING OPTIONS

#
# Protocol families:
#  Only the INET (Internet) family is officially supported in FreeBSD.
#  Source code for the NS (Xerox Network Service), ISO (OSI), and
#  CCITT (X.25) families is provided for amusement value, although we
#  try to ensure that it actually compiles.

#
# Network interfaces:
#  The `loop' pseudo-device is mandatory when networking is enabled.
#  The `ether' pseudo-device provides generic code to handle
#  Ethernets; it is mandatory when a Ethernet device driver is
#  configured.
#  The `sl' pseudo-device implements the Serial Line IP (SLIP) service.

# MROUTING enables the kernel multicast packet forwarder, which works
# with mrouted(8).
#
# The `bpfilter' pseudo-device enables the Berkeley Packet Filter.  Be
# aware of the legal and administrative consequences of enabling this
# option.  The number of devices determines the maximum number of
# simultaneous BPF clients programs runnable.

# FILESYSTEM OPTIONS

#
# Only the root, /usr, and /tmp filesystems need be statically
# compiled; everything else will be automatically loaded at mount
# time.  (Exception: the UFS family---FFS, MFS, and LFS---cannot
# currently be demand-loaded.)  Some people still prefer to statically
# compile other filesystems as well.
#
# NB: The LFS, PORTAL, and UNION filesystems are known to be buggy,
# and WILL panic your system if you attempt to do anything with them.
# They are included here as an incentive for some enterprising soul to
# sit down and fix them.
#

# One of these is mandatory:
options         FFS                     #Fast filesystem
options         NFS                     #Network File System

# The rest are optional:

options         UNION                   #Union filesystem

#
# Disk quotas are supported when this option is enabled.  If you
# change the value of this option, you must do a `make clean' in your
# kernel compile directory in order to get a working kernel.

# SCSI DEVICE CONFIGURATION

#
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device drivers, and the low-level host-adapter
# device drivers.  The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Note that, unlike most similar systems, the FreeBSD SCSI system
# does not wire a particular device unit number to any specific
# SCSI bus unit number.  Rather, unit numbers are assigned in the
# order that the devices are found on the SCSI bus.  (This means that
# if you remove a disk drive, you may have to rewrite your /etc/fstab
# file.)  It is expected that this will change for FreeBSD 2.1.

# MISCELLANEOUS DEVICES AND OPTIONS

#
# Of these, only the `log' device is truly mandatory.  The `pty'

# among others.

# HARDWARE DEVICE CONFIGURATION

# ISA and EISA devices:
# Currently there is no separate support for EISA.  There should be.
# Micro Channel is not supported at all.

#
# Mandatory ISA devices: isa, sc, npx
#
controller      isa0

#
# Options for `isa':
#
# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so
# that the PS/2 mouse driver doesn't conflict with the console driver.
#
# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so
# that multiple devices can share the same IRQ, provided that the
# hardware supports it (it usually doesn't).
#
# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
# than 16 megabytes of memory.  It doesn't hurt on other machines.
# Some broken EISA and VLB hardware may need this, too.

# NCONS specifies the number of virtual consoles.  Specification of
# this value is mandatory.  Due to a compiler bug, when compiling with
# GCC 2.6.0 this option must be a power of two.
#
# FAT_CURSOR specifies the use of a large block cursor rather than the
# hardware default underline.
#
# HARDFONTS allows the driver to load an ISO-8859-1 font to replace
