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.

341519d15cSJohn Baldwin# after an option or device should use one space after the comment character.

81480c6b8aSGreg Lehey# FreeBSD processes are subject to certain limits to their consumption
82480c6b8aSGreg Lehey# of system resources.  See getrlimit(2) for more details.  Each
83480c6b8aSGreg Lehey# resource limit has two values, a "soft" limit and a "hard" limit.
84480c6b8aSGreg Lehey# The soft limits can be modified during normal system operation, but
85480c6b8aSGreg Lehey# the hard limits are set at boot time.  Their default values are
86480c6b8aSGreg Lehey# in sys/<arch>/include/vmparam.h.  There are two ways to change them:
87480c6b8aSGreg Lehey#
88480c6b8aSGreg Lehey# 1.  Set the values at kernel build time.  The options below are one
89480c6b8aSGreg Lehey#     way to allow that limit to grow to 1GB.  They can be increased
90480c6b8aSGreg Lehey#     further by changing the parameters:
913236b30eSGreg Lehey#
92480c6b8aSGreg Lehey# 2.  In /boot/loader.conf, set the tunables kern.maxswzone,

11536a8d6623SGarrett Wollman
11546a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
1155ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
11566a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI

11586a8d6623SGarrett Wollman#
1159e14eb5a1SGarrett Wollman# It is possible to wire down your SCSI devices so that a given bus,
1160e14eb5a1SGarrett Wollman# target, and LUN always come on line as the same device unit.  In
1161e14eb5a1SGarrett Wollman# earlier versions the unit numbers were assigned in the order that
1162e14eb5a1SGarrett Wollman# the devices were probed on the SCSI bus.  This means that if you
1163e14eb5a1SGarrett Wollman# removed a disk drive, you may have had to rewrite your /etc/fstab
1164e14eb5a1SGarrett Wollman# file, and also that you had to be careful when adding a new disk
1165e14eb5a1SGarrett Wollman# as it may have been probed earlier and moved your device configuration
