813 # SCSI DEVICE CONFIGURATION
815 # The SCSI subsystem consists of the `base' SCSI code, a number of
816 # high-level SCSI device `type' drivers, and the low-level host-adapter
817 # device drivers. The host adapters are listed in the ISA and PCI
818 # device configuration sections below.
820 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
821 # that a given bus, target, and LUN always come on line as the same
822 # device unit. In earlier versions the unit numbers were assigned
823 # in the order that the devices were probed on the SCSI bus. This
824 # means that if you removed a disk drive, you may have had to rewrite
825 # your /etc/fstab file, and also that you had to be careful when adding
826 # a new disk as it may have been probed earlier and moved your device
827 # configuration around.
829 # This old behavior is maintained as the default behavior. The unit
830 # assignment begins with the first non-wired down unit for a device
831 # type. For example, if you wire a disk as "da3" then the first
832 # non-wired disk will be assigned da4.
834 # The syntax for wiring down devices is:
836 hint.scbus.0.at="ahc0"
837 hint.scbus.1.at="ahc1"
839 hint.scbus.3.at="ahc2"

854 # treated as if specified as LUN 0.

860 # The da driver drives SCSI Direct Access ("disk") and Optical Media
863 # The sa driver drives SCSI Sequential Access ("tape") devices.
865 # The cd driver drives SCSI Read Only Direct Access ("cd") devices.
867 # The ses driver drives SCSI Envinronment Services ("ses") and
868 # SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices.
870 # The pt driver drives SCSI Processor devices.
873 # Target Mode support is provided here but also requires that a SIM
874 # (SCSI Host Adapter Driver) provide support as well.
876 # The targ driver provides target mode support as a Processor type device.
877 # It exists to give the minimal context necessary to respond to Inquiry
878 # commands. There is a sample user application that shows how the rest
879 # of the command support might be done in /usr/share/examples/scsi_target.

2011 # Notes on the Specialix SI/XIO driver:

2013 # The Rev 1 host cards use a 64K chunk, on a 32K boundary.
2014 # The Rev 2 host cards use a 32K chunk, on a 32K boundary.
2015 # The cards can use an IRQ of 11, 12 or 15.
2017 # Notes on the Sony Programmable I/O controller
2018 # This is a temporary driver that should someday be replaced by something
2019 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
2020 # General Device 10 decoder, which means you have to fiddle with PCI
2021 # registers to map it in, even though it is otherwise treated here as
2022 # an ISA device. At the moment, the driver polls, although the device
2023 # is capable of generating interrupts. It largely undocumented.
2024 # The port location in the hint is where you WANT the device to be
2025 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2026 # is the only thing truly supported, but aparently a fair percentage
2027 # of the Vaio extra features are controlled by this device.

2031 # This is version 0.0.5alpha, unsupported by Stallion.
