4#
5# Lines that begin with 'device', 'options', 'machine', 'ident', 'maxusers',
6# 'makeoptions', 'hints', etc. go into the kernel configuration that you
7# run config(8) with.
8#
9# Lines that begin with 'hint.' are NOT for config(8), they go into your
10# hints file. See /boot/device.hints and/or the 'hints' config(8) directive.

12# Please use ``make LINT'' to create an old-style LINT file if you want to
13# do kernel test-builds.

20# NOTES conventions and style guide:
21#
22# Large block comments should begin and end with a line containing only a
23# comment character.
24#
25# To describe a particular object, a block comment (if it exists) should
26# come first. Next should come device, options, and hints lines in that
27# order. All device and option lines must be described by a comment that
28# doesn't just expand the device or option name. Use only a concise
29# comment on the same line if possible. Very detailed descriptions of
30# devices and subsystems belong in manpages.
31#
32# A space followed by a tab separates 'option' from an option name. Two
33# spaces followed by a tab separate 'device' from a device name. Comments
34# after an option or device should use one space after the comment character.
35# To comment out a negative option that disables code and thus should not be
36# enabled for LINT builds, precede 'option' with "#!".
37#

40# This is the ``identification'' of the kernel. Usually this should
41# be the same as the name of your kernel.

46# The `maxusers' parameter controls the static sizing of a number of
47# internal system tables by a formula defined in subr_param.c.
48# Omitting this parameter or setting it to 0 will cause the system to
49# auto-size based on physical memory.

54# The `makeoptions' parameter allows variables to be passed to the

57# CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
58# after most other flags. Here we use it to inhibit use of non-optimal

61# DEBUG happens to be magic.
62# The following is equivalent to 'config -g KERNELNAME' and creates
63# 'kernel.debug' compiled with -g debugging as well as a normal

65# but that isn't normally necessary as the debug symbols are not loaded
66# by the kernel and are not useful there anyway.

839# SCSI DEVICES
840
841# SCSI DEVICE CONFIGURATION
842
843# The SCSI subsystem consists of the `base' SCSI code, a number of
844# high-level SCSI device `type' drivers, and the low-level host-adapter
845# device drivers. The host adapters are listed in the ISA and PCI
846# device configuration sections below.
847#
848# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
849# that a given bus, target, and LUN always come on line as the same
850# device unit. In earlier versions the unit numbers were assigned
851# in the order that the devices were probed on the SCSI bus. This
852# means that if you removed a disk drive, you may have had to rewrite
853# your /etc/fstab file, and also that you had to be careful when adding
854# a new disk as it may have been probed earlier and moved your device
855# configuration around.
856
857# This old behavior is maintained as the default behavior. The unit
858# assignment begins with the first non-wired down unit for a device
859# type. For example, if you wire a disk as "da3" then the first
860# non-wired disk will be assigned da4.
861
862# The syntax for wiring down devices is:

1544# the MPX 5030/5038, which is either a RealTek in disguise or a
1545# RealTek workalike. Note that the D-Link DFE-530TX+ uses the RealTek

22# Large block comments should begin and end with a line containing only a

24#
25# To describe a particular object, a block comment (if it exists) should
26# come first. Next should come device, options, and hints lines in that
27# order. All device and option lines must be described by a comment that
28# doesn't just expand the device or option name. Use only a concise
29# comment on the same line if possible. Very detailed descriptions of
30# devices and subsystems belong in manpages.
31#
32# A space followed by a tab separates 'option' from an option name. Two
33# spaces followed by a tab separate 'device' from a device name. Comments
34# after an option or device should use one space after the comment character.
35# To comment out a negative option that disables code and thus should not be
36# enabled for LINT builds, precede 'option' with "#!".

839# SCSI DEVICES
840
841# SCSI DEVICE CONFIGURATION
842
843# The SCSI subsystem consists of the `base' SCSI code, a number of
844# high-level SCSI device `type' drivers, and the low-level host-adapter
845# device drivers. The host adapters are listed in the ISA and PCI
846# device configuration sections below.
847#
848# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
849# that a given bus, target, and LUN always come on line as the same
850# device unit. In earlier versions the unit numbers were assigned
851# in the order that the devices were probed on the SCSI bus. This
852# means that if you removed a disk drive, you may have had to rewrite
853# your /etc/fstab file, and also that you had to be careful when adding
854# a new disk as it may have been probed earlier and moved your device
855# configuration around.
856
857# This old behavior is maintained as the default behavior. The unit
858# assignment begins with the first non-wired down unit for a device
859# type. For example, if you wire a disk as "da3" then the first
860# non-wired disk will be assigned da4.
861
862# The syntax for wiring down devices is:
863
864hint.scbus.0.at="ahc0"
865hint.scbus.1.at="ahc1"
866hint.scbus.1.bus="0"

1804# If instead you have two ISA cards, one installed at 0x100 and the

1809# hint.rp.1.at="isa"
1810# hint.rp.1.port="0x180"

1812# For 4 ISA cards, it might be something like this:
