733
734# SCSI DEVICE CONFIGURATION
735
736# The SCSI subsystem consists of the `base' SCSI code, a number of
737# high-level SCSI device `type' drivers, and the low-level host-adapter
738# device drivers. The host adapters are listed in the ISA and PCI
739# device configuration sections below.
740#
741# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
742# that a given bus, target, and LUN always come on line as the same
743# device unit. In earlier versions the unit numbers were assigned
744# in the order that the devices were probed on the SCSI bus. This
745# means that if you removed a disk drive, you may have had to rewrite
746# your /etc/fstab file, and also that you had to be careful when adding
747# a new disk as it may have been probed earlier and moved your device
748# configuration around.
749
750# This old behavior is maintained as the default behavior. The unit
751# assignment begins with the first non-wired down unit for a device
752# type. For example, if you wire a disk as "da3" then the first
753# non-wired disk will be assigned da4.
754
755# The syntax for wiring down devices is:
756
757# device scbus0 at ahc0 # Single bus device
758# device scbus1 at ahc1 bus 0 # Single bus device
759# device scbus3 at ahc2 bus 0 # Twin bus device
760# device scbus2 at ahc2 bus 1 # Twin bus device
761# device da0 at scbus0 target 0 unit 0
762# device da1 at scbus3 target 1
763# device da2 at scbus2 target 3
764# device sa1 at scbus1 target 6
765# device cd
766
767# "units" (SCSI logical unit number) that are not specified are
768# treated as if specified as LUN 0.
769
770# All SCSI devices allocate as many units as are required.

742# that a given bus, target, and LUN always come on line as the same
743# device unit. In earlier versions the unit numbers were assigned
744# in the order that the devices were probed on the SCSI bus. This
745# means that if you removed a disk drive, you may have had to rewrite
746# your /etc/fstab file, and also that you had to be careful when adding
747# a new disk as it may have been probed earlier and moved your device
748# configuration around.
749
750# This old behavior is maintained as the default behavior. The unit
751# assignment begins with the first non-wired down unit for a device
752# type. For example, if you wire a disk as "da3" then the first
753# non-wired disk will be assigned da4.
754
755# The syntax for wiring down devices is:
756
757# device scbus0 at ahc0 # Single bus device
758# device scbus1 at ahc1 bus 0 # Single bus device
759# device scbus3 at ahc2 bus 0 # Twin bus device
760# device scbus2 at ahc2 bus 1 # Twin bus device
761# device da0 at scbus0 target 0 unit 0
762# device da1 at scbus3 target 1
763# device da2 at scbus2 target 3
764# device sa1 at scbus1 target 6
765# device cd
766
767# "units" (SCSI logical unit number) that are not specified are
768# treated as if specified as LUN 0.
769
770# All SCSI devices allocate as many units as are required.
771

773# configuration and doesn't have to be explicitly configured.

906#
907# MAXMEM specifies the amount of RAM on the machine; if this is not

1428# Notes on the Comtrol Rocketport driver:
1429#
1430# The exact values used for rp0 depend on how many boards you have

1432#
1433# Comtrol Rocketport ISA single card

1435#
1436# If instead you have two ISA cards, one installed at 0x100 and the
1437# second installed at 0x180, then you should add the following to
1438# your kernel configuration file:
1439#
1440# device rp0 at isa? port 0x100
1441# device rp1 at isa? port 0x180
1442#
1443# For 4 ISA cards, it might be something like this:

1446# device rp1 at isa? port 0x100
1447# device rp2 at isa? port 0x340
1448# device rp3 at isa? port 0x240
1449#
1450# And for PCI cards, you only need say:
1451#
1452# device rp
1453
1454# Notes on the Digiboard driver:
1455#
1456# The following flag values have special meanings:
1457# 0x01 - alternate layout of pins (dgb & dgm)
1458# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1459
1460# Notes on the Specialix SI/XIO driver:
1461# **This is NOT a Specialix supported Driver!**
1462# The host card is memory, not IO mapped.
1463# The Rev 1 host cards use a 64K chunk, on a 32K boundary.

2182# (the /usr/sbin/svr4 script does this for you). If compiling statically,
2183# the `streams' pseudo-device must be configured into any kernel which also
2184# specifies COMPAT_SVR4. It is possible to have a statically-configured
2185# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2186# script understands that it doesn't need to load the `streams' module under
2187# those circumstances.

2198# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2199# Compaq are actually DPT controllers.
2200#

2205# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.

2207# this option. If your system is very busy, this
2208# option will create more trouble than solve.

1614# supports the Accton EN1207D `Cheetah' adapter, which uses a chip called
1615# the MPX 5030/5038, which is either a RealTek in disguise or a RealTek
1616# workalike. Note that the D-Link DFE-530TX+ uses the RealTek chipset
1617# and is supported by this driver, not the 'vr' driver.
1618#

1638# attach each one as a separate network interface.
1639#
1640# The 'ti' device provides support for PCI gigabit ethernet NICs based
1641# on the Alteon Networks Tigon 1 and Tigon 2 chipsets. This includes the
1642# Alteon AceNIC, the 3Com 3c985, the Netgear GA620 and various others.
1643# Note that you will probably want to bump up NMBCLUSTERS a lot to use
1644# this driver.
1645#
1646# The 'tl' device provides support for the Texas Instruments TNETE100
1647# series 'ThunderLAN' cards and integrated ethernet controllers. This

1657# chips, including the D-Link DFE530TX (see 'rl' for DFE530TX+), the Hawking
1658# Technologies PN102TX, and the AOpen/Acer ALN-320.
1659#
1660# The `vx' device provides support for the 3Com 3C590 and 3C595
1661# early support
1662#
1663# The `wb' device provides support for various fast ethernet adapters
1664# based on the Winbond W89C840F chip. Note: this is not the same as

1680# following options:
1681# options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry
1682# figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE
1683# options METEOR_DEALLOC_PAGES remove all allocated pages on close(2)
1684# options METEOR_DEALLOC_ABOVE=xxx remove all allocated pages above the
1685# specified amount. If this value is below the allocated amount no action
1686# taken
1687# options METEOR_SYSTEM_DEFAULT={METEOR_PAL|METEOR_NTSC|METEOR_SECAM}, used
1688# for initialization of fps routine when a signal is not present.
1689#
1690# The 'bktr' device is a PCI video capture device using the Brooktree
1691# bt848/bt848a/bt849a/bt878/bt879 chipset. When used with a TV Tuner it forms a

1706# Specifes the default video capture mode.
1707# This is required for Dual Crystal (28&35Mhz) boards where PAL is used
1708# to prevent hangs during initialisation. eg VideoLogic Captivator PCI.
1709#
1710# options BKTR_USE_PLL
1711# PAL or SECAM users who have a 28Mhz crystal (and no 35Mhz crystal)
1712# must enable PLL mode with this option. eg some new Bt878 cards.

2184# STREAMS device and a dynamically loadable svr4 emulator; the /usr/sbin/svr4
2185# script understands that it doesn't need to load the `streams' module under
2186# those circumstances.

2194# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
2195# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
2196# The DPT controllers are commonly re-licensed under other brand-names -
2197# some controllers by Olivetti, Dec, HP, AT&T, SNI, AST, Alphatronic, NEC and
2198# Compaq are actually DPT controllers.
2199#
2200# See src/sys/dev/dpt for debugging and other subtle options.
2201# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
2202# instruments are enabled. The tools in
2203# /usr/sbin/dpt_* assume these to be enabled.
2204# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
2205# If you ant the driver to handle timeouts, enable
2206# this option. If your system is very busy, this
2207# option will create more trouble than solve.
2208# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
2209# wait when timing out with the above option.
2210# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
2211# DPT_LOST_IRQ When enabled, will try, once per second, to catch
2212# any interrupt that got lost. Seems to help in some
2213# DPT-firmware/Motherboard combinations. Minimal
2214# cost, great benefit.
2215# DPT_RESET_HBA Make "reset" actually reset the controller
2216# instead of fudging it. Only enable this if you
2217# are 100% certain you need it.
