4816a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
4826a8d6623SGarrett Wollman
4836a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
484ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
4856a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
4866a8d6623SGarrett Wollman# device configuration sections below.
4876a8d6623SGarrett Wollman#
488265368d4SRodney W. Grimes# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
489ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
490ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
491ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
492ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
493ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
494ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
495ebc1a0e2SPeter Dufault# configuration around.
496ebc1a0e2SPeter Dufault
497ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
498ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
499ebc1a0e2SPeter Dufault# type.  For example, if you wire a disk as "sd3" then the first
500ebc1a0e2SPeter Dufault# non-wired disk will be assigned sd4.

1134c4823710SPeter Wemm#  **This is NOT a Specialix supported Driver!**
1135c4823710SPeter Wemm#  The host card is memory, not IO mapped.
1136c4823710SPeter Wemm#  The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1137c4823710SPeter Wemm#  The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1138c4823710SPeter Wemm#  The cards can use an IRQ of 11, 12 or 15.

1140c9da1b81SPeter Wemm# Notes on the Stallion stl and stli drivers:

1143c9da1b81SPeter Wemm#  The stl driver has a secondary IO port hard coded at 0x280.  You need
1144c9da1b81SPeter Wemm#     to change src/i386/isa/stallion.c if you reconfigure this on the boards.
