7196a8d6623SGarrett Wollman
7206a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
721ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
7226a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI

725265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
726ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
727ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
728ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
729ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
730ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
731ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
