# FILESYSTEM OPTIONS

# Only the root, /usr, and /tmp filesystems need be statically

# 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.

# Note: 4.4BSD NQNFS lease checking has relatively high cost for

#####################################################################
# SCSI DEVICES
# SCSI OPTIONS:
# SCSIDEBUG: When defined enables debugging macros
# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k)
# SCSI DEVICE CONFIGURATION
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers. The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.1 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit. In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus. This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.
# This old behavior is maintained as the default behavior. The unit
# assignment begins with the first non-wired down unit for a device
# type. For example, if you wire a disk as "sd3" then the first
# non-wired disk will be assigned sd4.
# The syntax for wiring down devices is:
# disk sd0 at scbus0 target 0 unit 0
# disk sd1 at scbus0 target 1
# disk sd2 at scbus0 target 3
# tape st1 at scbus0 target 6
# device cd0 at scbus?
# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.
# All SCSI devices allocate as many units as are required.
# The "unknown" device (uk? in pre-2.1) is now part of the base SCSI
# configuration and doesn't have to be explicitly configured.
controller scbus0 #base SCSI code
device ch0 #SCSI media changers
device sd0 #SCSI disks
device st0 #SCSI tapes
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.
#
pseudo-device pty 16 #Pseudo ttys - can go as high as 64
pseudo-device speaker #Play IBM BASIC-style noises out your speaker
pseudo-device log #Kernel syslog interface (/dev/klog)
pseudo-device gzip #Exec gzipped a.out's
pseudo-device vn #Vnode driver (turns a file into a device)
pseudo-device snp 3 #Snoop device - to look at pty/vty/etc..
#####################################################################
# 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
# included so that people with sound cards that support multiple emulations
# can setup different sound drivers on the same DMA channel. There are no
# other known uses for this option.
#
# 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.
#
# 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.

# PCI devices:
#
# The main PCI bus device is `pci'. It provides auto-detection and
# configuration support for all devices on the PCI bus, using either
# configuration mode defined in the PCI specification.
#
# The `ncr' device provides support for the NCR 53C810 and 53C825
# self-contained SCSI host adapters.
#
# The `de' device provides support for the Digital Equipment DC21040
# self-contained Ethernet adapter.
#
# The `fpa' device provides support for the Digital DEFPA PCI FDDI
# adapter. pseudo-device fddi is also needed.
#
# The PROBE_VERBOSE option enables a long listing of chip set registers
# for supported PCI chip sets (currently only intel Saturn and Mercury).
