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

844 # treated as if specified as LUN 0.
846 # All SCSI devices allocate as many units as are required.
848 # The ch driver drives SCSI Media Changer ("jukebox") devices.
850 # The da driver drives SCSI Direct Access ("disk") and Optical Media
853 # The sa driver drives SCSI Sequential Access ("tape") devices.
855 # The cd driver drives SCSI Read Only Direct Access ("cd") devices.
857 # The ses driver drives SCSI Envinronment Services ("ses") and
858 # SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices.
860 # The pt driver drives SCSI Processor devices.
863 # Target Mode support is provided here but also requires that a SIM
864 # (SCSI Host Adapter Driver) provide support as well.
866 # The targ driver provides target mode support as a Processor type device.
867 # It exists to give the minimal context necessary to respond to Inquiry
868 # commands. There is a sample user application that shows how the rest
869 # of the command support might be done in /usr/share/examples/scsi_target.

872 # to incoming commands that do not otherwise have a logical unit assigned

1990 # 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1992 # Notes on the Specialix SI/XIO driver:
1993 # The host card is memory, not IO mapped.
1994 # The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1995 # The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1996 # The cards can use an IRQ of 11, 12 or 15.
1998 # Notes on the Sony Programmable I/O controller
1999 # This is a temporary driver that should someday be replaced by something
2000 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
2001 # General Device 10 decoder, which means you have to fiddle with PCI
2002 # registers to map it in, even though it is otherwise treated here as
2003 # an ISA device. At the moment, the driver polls, although the device
2004 # is capable of generating interrupts. It largely undocumented.
2005 # The port location in the hint is where you WANT the device to be
2006 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2007 # is the only thing truly supported, but aparently a fair percentage
2008 # of the Vaio extra features are controlled by this device.
2010 # Notes on the Stallion stl and stli drivers:

2012 # This is version 0.0.5alpha, unsupported by Stallion.
2013 # The stl driver has a secondary IO port hard coded at 0x280. You need
