The host adapters are listed in the ISA and PCI 582# device configuration sections below. 583# 584# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 585# that a given bus, target, and LUN always come on line as the same 586# device unit. In earlier versions the unit numbers were assigned 587# in the order that the devices were probed on the SCSI bus. This 588# means that if you removed a disk drive, you may have had to rewrite 589# your /etc/fstab file, and also that you had to be careful when adding 590# a new disk as it may have been probed earlier and moved your device 591# configuration around. 592 593# This old behavior is maintained as the default behavior. The unit 594# assignment begins with the first non-wired down unit for a device 595# type.
