The host adapters are listed in the ISA and PCI 476# device configuration sections below. 477# 478# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so 479# that a given bus, target, and LUN always come on line as the same 480# device unit. In earlier versions the unit numbers were assigned 481# in the order that the devices were probed on the SCSI bus. This 482# means that if you removed a disk drive, you may have had to rewrite 483# your /etc/fstab file, and also that you had to be careful when adding 484# a new disk as it may have been probed earlier and moved your device 485# configuration around. 486 487# This old behavior is maintained as the default behavior. The unit 488# assignment begins with the first non-wired down unit for a device 489# type.
