# This directive is mandatory; it defines the architecture to be

#
# 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

#
# 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 `sppp' pseudo-device serves a similar role for certain types
#  of synchronous PPP links (like `cx').
#  The `sl' pseudo-device implements the Serial Line IP (SLIP) service.
#  The `ppp' pseudo-device implements the Point-to-Point Protocol.
#  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.
#  The `disc' pseudo-device implements a minimal network interface,
#  which throws away all packets sent and never receives any.  It is
#  included for testing purposes.

# larger static sizes of a number of system tables.
#
# MROUTING enables the kernel multicast packet forwarder, which works

# FILESYSTEM OPTIONS

#
# Only the root, /usr, and /tmp filesystems need be statically
# compiled; everything else will be automatically loaded at mount

# 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.

# 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.
#
controller	scbus0	#base SCSI code
device		ch0	#SCSI media changers
device		sd0	#SCSI disks
device		st0	#SCSI tapes
device		uk0			#unknown scsi devices

#
# The `cd' (SCSI read-only removable disk) driver is special in that
# the code dynamically allocates more units as they are required, with
# no limit (other than memory) to the number available.
device		cd0	#SCSI CD-ROMs


#####################################################################
# MISCELLANEOUS DEVICES AND OPTIONS

#
# Of these, only the `log' device is truly mandatory.  The `pty'
# device usually turns out to be ``effectively mandatory'', as it is
# required for `telnetd', `rlogind', `screen', `emacs', and `xterm',
# 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_DRQ suppresses the DMA conflict checks.  This option is
# not known to be good for anything.
#
# 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).
#
# ALLOW_CONFLICT_MEMADDR suppresses the memory address conflict checks.
# This option is not known to be good for anything.
#
# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
# interrupt controller.  This saves about 1.25 usec for each interrupt.
# No problems are known to be caused by this option.
#
# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
# interrupt controller.  This saves about 1.25 usec for each interrupt.
# Automatic EOI is documented not to work for for the slave with the
# original i8259A, but it works for some clones and some integrated
# versions.
#
# 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.
#
# DISKSLICE provides support for slicing up a disk into virtual disks.
# It isn't really ISA-specific, but the on-disk slice table is currently
# required to be a DOS partition table.
#
# DUMMY_NOPS disables extra delays for some bus operations.  The delays
# are mostly for older systems and aren't used consistently.  Probably
# works OK on most EISA bus machines.
#
# TUNE_1542 enables the automatic ISA bus speed selection for the
# Adaptec 1542 boards. Does not work for all boards, use it with caution.
