221519d15cSJohn Baldwin# Large block comments should begin and end with a line containing only a
231519d15cSJohn Baldwin# comment character.
241519d15cSJohn Baldwin#
251519d15cSJohn Baldwin# To describe a particular object, a block comment (if it exists) should
261519d15cSJohn Baldwin# come first.  Next should come device, options, and hints lines in that
271519d15cSJohn Baldwin# order.  All device and option lines must be described by a comment that
281519d15cSJohn Baldwin# doesn't just expand the device or option name.  Use only a concise
291519d15cSJohn Baldwin# comment on the same line if possible.  Very detailed descriptions of
301519d15cSJohn Baldwin# devices and subsystems belong in man pages.
311519d15cSJohn Baldwin#
32eb4f7a81SNate Lawson# A space followed by a tab separates 'options' from an option name.  Two
331519d15cSJohn Baldwin# spaces followed by a tab separate 'device' from a device name.  Comments
341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.
351519d15cSJohn Baldwin# To comment out a negative option that disables code and thus should not be
36eb4f7a81SNate Lawson# enabled for LINT builds, precede 'options' with "#!".

9516a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
9526a8d6623SGarrett Wollman
9536a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
954ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
9556a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
9566a8d6623SGarrett Wollman# device configuration sections below.
9576a8d6623SGarrett Wollman#
958e14eb5a1SGarrett Wollman# It is possible to wire down your SCSI devices so that a given bus,
959e14eb5a1SGarrett Wollman# target, and LUN always come on line as the same device unit.  In
960e14eb5a1SGarrett Wollman# earlier versions the unit numbers were assigned in the order that
961e14eb5a1SGarrett Wollman# the devices were probed on the SCSI bus.  This means that if you
962e14eb5a1SGarrett Wollman# removed a disk drive, you may have had to rewrite your /etc/fstab
963e14eb5a1SGarrett Wollman# file, and also that you had to be careful when adding a new disk
964e14eb5a1SGarrett Wollman# as it may have been probed earlier and moved your device configuration
965e14eb5a1SGarrett Wollman# around.  (See also option GEOM_VOL for a different solution to this
966e14eb5a1SGarrett Wollman# problem.)
967ebc1a0e2SPeter Dufault
968ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
969ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
970700daf5eSJustin T. Gibbs# type.  For example, if you wire a disk as "da3" then the first
971700daf5eSJustin T. Gibbs# non-wired disk will be assigned da4.

1670d61e6649SAlexander Langer#       chipset.  Note that the RealTek driver defaults to using programmed
1671d61e6649SAlexander Langer#       I/O to do register accesses because memory mapped mode seems to cause
1672d61e6649SAlexander Langer#       severe lockups on SMP hardware.  This driver also supports the
1673d61e6649SAlexander Langer#       Accton EN1207D `Cheetah' adapter, which uses a chip called
1674d61e6649SAlexander Langer#       the MPX 5030/5038, which is either a RealTek in disguise or a
1675d61e6649SAlexander Langer#       RealTek workalike.  Note that the D-Link DFE-530TX+ uses the RealTek
1676d61e6649SAlexander Langer#       chipset and is supported by this driver, not the 'vr' driver.
1677d61e6649SAlexander Langer# sf:   Support for Adaptec Duralink PCI fast ethernet adapters based on the

1679d61e6649SAlexander Langer#       This includes dual and quad port cards, as well as one 100baseFX card.
1680d61e6649SAlexander Langer#       Most of these are 64-bit PCI devices, except for one single port
1681d61e6649SAlexander Langer#       card which is 32-bit.

1688d61e6649SAlexander Langer#       (also single mode and multimode).
1689d61e6649SAlexander Langer#       The driver will autodetect the number of ports on the card and
1690d61e6649SAlexander Langer#       attach each one as a separate network interface.

1698d61e6649SAlexander Langer#       probably want to bump up NMBCLUSTERS a lot to use this driver.
