607 # SCSI DEVICE CONFIGURATION
609 # The SCSI subsystem consists of the `base' SCSI code, a number of
610 # high-level SCSI device `type' drivers, and the low-level host-adapter
611 # device drivers. The host adapters are listed in the ISA and PCI
612 # device configuration sections below.
614 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
615 # that a given bus, target, and LUN always come on line as the same
616 # device unit. In earlier versions the unit numbers were assigned
617 # in the order that the devices were probed on the SCSI bus. This
618 # means that if you removed a disk drive, you may have had to rewrite
619 # your /etc/fstab file, and also that you had to be careful when adding
620 # a new disk as it may have been probed earlier and moved your device
621 # configuration around.
623 # This old behavior is maintained as the default behavior. The unit
624 # assignment begins with the first non-wired down unit for a device
625 # type. For example, if you wire a disk as "da3" then the first
626 # non-wired disk will be assigned da4.
628 # The syntax for wiring down devices is:
630 # controller scbus0 at ahc0 # Single bus device
631 # controller scbus1 at ahc1 bus 0 # Single bus device
632 # controller scbus3 at ahc2 bus 0 # Twin bus device
633 # controller scbus2 at ahc2 bus 1 # Twin bus device
634 # disk da0 at scbus0 target 0 unit 0
635 # disk da1 at scbus3 target 1
636 # disk da2 at scbus2 target 3
637 # tape st1 at scbus1 target 6
638 # device cd0 at scbus?
640 # "units" (SCSI logical unit number) that are not specified are
641 # treated as if specified as LUN 0.
643 # All SCSI devices allocate as many units as are required.
645 # The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
646 # configuration and doesn't have to be explicitly configured.

764 # MAXMEM specifies the amount of RAM on the machine; if this is not
765 # specified, FreeBSD will first read the amount of memory from the CMOS

767 # depending on the BIOS. If the BIOS reports 64MB, a memory probe will
768 # then attempt to detect the installed amount of RAM. If this probe
769 # fails to detect >64MB RAM you will have to use the MAXMEM option.
