2646a8d6623SGarrett Wollman# SCSI DEVICE CONFIGURATION
2656a8d6623SGarrett Wollman
2666a8d6623SGarrett Wollman# The SCSI subsystem consists of the `base' SCSI code, a number of
267ebc1a0e2SPeter Dufault# high-level SCSI device `type' drivers, and the low-level host-adapter
2686a8d6623SGarrett Wollman# device drivers.  The host adapters are listed in the ISA and PCI
2696a8d6623SGarrett Wollman# device configuration sections below.
2706a8d6623SGarrett Wollman#
271ebc1a0e2SPeter Dufault# Beginning with FreeBSD 2.1 you can wire down your SCSI devices so
272ebc1a0e2SPeter Dufault# that a given bus, target, and LUN always come on line as the same
273ebc1a0e2SPeter Dufault# device unit.  In earlier versions the unit numbers were assigned
274ebc1a0e2SPeter Dufault# in the order that the devices were probed on the SCSI bus.  This
275ebc1a0e2SPeter Dufault# means that if you removed a disk drive, you may have had to rewrite
276ebc1a0e2SPeter Dufault# your /etc/fstab file, and also that you had to be careful when adding
277ebc1a0e2SPeter Dufault# a new disk as it may have been probed earlier and moved your device
278ebc1a0e2SPeter Dufault# configuration around.
279ebc1a0e2SPeter Dufault
280ebc1a0e2SPeter Dufault# This old behavior is maintained as the default behavior.  The unit
281ebc1a0e2SPeter Dufault# assignment begins with the first non-wired down unit for a device
282ebc1a0e2SPeter Dufault# type.  For example, if you wire a disk as "sd3" then the first
283ebc1a0e2SPeter Dufault# non-wired disk will be assigned sd4.
284ebc1a0e2SPeter Dufault
285ebc1a0e2SPeter Dufault# The syntax for wiring down devices is:
286ebc1a0e2SPeter Dufault
287ebc1a0e2SPeter Dufault# disk sd0 at scbus0 target 0 unit 0
288ebc1a0e2SPeter Dufault# disk sd1 at scbus0 target 1

3449ba0e7c3SBruce Evans# ALLOW_CONFLICT_DRQ suppresses the DMA conflict checks.  This option is
345ca83dc2dSJordan K. Hubbard# included so that people with sound cards that support multiple emulations
346ca83dc2dSJordan K. Hubbard# can setup different sound drivers on the same DMA channel.  There are no
347ca83dc2dSJordan K. Hubbard# other known uses for this option.
3489ba0e7c3SBruce Evans#
3496a8d6623SGarrett Wollman# ALLOW_CONFLICT_IOADDR suppresses the I/O address conflict checks, so
3506a8d6623SGarrett Wollman# that the PS/2 mouse driver doesn't conflict with the console driver.
3516a8d6623SGarrett Wollman#
3526a8d6623SGarrett Wollman# ALLOW_CONFLICT_IRQ suppresses the interrupt line conflict checks, so
3536a8d6623SGarrett Wollman# that multiple devices can share the same IRQ, provided that the
3546a8d6623SGarrett Wollman# hardware supports it (it usually doesn't).
3556a8d6623SGarrett Wollman#
3569ba0e7c3SBruce Evans# ALLOW_CONFLICT_MEMADDR suppresses the memory address conflict checks.
3579ba0e7c3SBruce Evans# This option is not known to be good for anything.

3599ba0e7c3SBruce Evans# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A

3639ba0e7c3SBruce Evans# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
