Next should come device, options, and hints lines in that 27254721Semaste# order. All device and option lines must be described by a comment that 28254721Semaste# doesn't just expand the device or option name. Use only a concise 29254721Semaste# comment on the same line if possible. Very detailed descriptions of 30254721Semaste# devices and subsystems belong in manpages. 31254721Semaste# 32254721Semaste# A space followed by a tab separates 'option' from an option name. Two 33254721Semaste# spaces followed by a tab separate 'device' from a device name. Comments 34254721Semaste# after an option or device should use one space after the comment character. 35254721Semaste# To comment out a negative option that disables code and thus should not be 36254721Semaste# enabled for LINT builds, precede 'option' with "#!". 37254721Semaste# 38254721Semaste 39254721Semaste# 40254721Semaste# This is the ``identification'' of the kernel.

The host adapters are listed in the ISA and PCI 799# device configuration sections below. 800# 801# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 802# that a given bus, target, and LUN always come on line as the same 803# device unit. In earlier versions the unit numbers were assigned 804# in the order that the devices were probed on the SCSI bus. This 805# means that if you removed a disk drive, you may have had to rewrite 806# your /etc/fstab file, and also that you had to be careful when adding 807# a new disk as it may have been probed earlier and moved your device 808# configuration around. 809 810# This old behavior is maintained as the default behavior. The unit 811# assignment begins with the first non-wired down unit for a device 812# type.
