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.

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#

46# The `maxusers' parameter controls the static sizing of a number of
47# internal system tables by a formula defined in subr_param.c.

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

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

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 "#!".

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