662
663# SCSI DEVICE CONFIGURATION
664
665# The SCSI subsystem consists of the `base' SCSI code, a number of
666# high-level SCSI device `type' drivers, and the low-level host-adapter
667# device drivers. The host adapters are listed in the ISA and PCI
668# device configuration sections below.
669#
670# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
671# that a given bus, target, and LUN always come on line as the same
672# device unit. In earlier versions the unit numbers were assigned
673# in the order that the devices were probed on the SCSI bus. This
674# means that if you removed a disk drive, you may have had to rewrite
675# your /etc/fstab file, and also that you had to be careful when adding
676# a new disk as it may have been probed earlier and moved your device
677# configuration around.
678
679# This old behavior is maintained as the default behavior. The unit
680# assignment begins with the first non-wired down unit for a device
681# type. For example, if you wire a disk as "da3" then the first
682# non-wired disk will be assigned da4.
683
684# The syntax for wiring down devices is:
685
686# controller scbus0 at ahc0 # Single bus device
687# controller scbus1 at ahc1 bus 0 # Single bus device
688# controller scbus3 at ahc2 bus 0 # Twin bus device
689# controller scbus2 at ahc2 bus 1 # Twin bus device
690# disk da0 at scbus0 target 0 unit 0
691# disk da1 at scbus3 target 1
692# disk da2 at scbus2 target 3
693# tape st1 at scbus1 target 6
694# device cd0 at scbus?
695
696# "units" (SCSI logical unit number) that are not specified are
697# treated as if specified as LUN 0.
698
699# All SCSI devices allocate as many units as are required.

661# SCSI DEVICES
662
663# SCSI DEVICE CONFIGURATION
664
665# The SCSI subsystem consists of the `base' SCSI code, a number of
666# high-level SCSI device `type' drivers, and the low-level host-adapter
667# device drivers. The host adapters are listed in the ISA and PCI
668# device configuration sections below.
669#
670# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
671# that a given bus, target, and LUN always come on line as the same
672# device unit. In earlier versions the unit numbers were assigned
673# in the order that the devices were probed on the SCSI bus. This
674# means that if you removed a disk drive, you may have had to rewrite
675# your /etc/fstab file, and also that you had to be careful when adding
676# a new disk as it may have been probed earlier and moved your device
677# configuration around.
678
679# This old behavior is maintained as the default behavior. The unit
680# assignment begins with the first non-wired down unit for a device
681# type. For example, if you wire a disk as "da3" then the first
682# non-wired disk will be assigned da4.
683
684# The syntax for wiring down devices is:
685
686# controller scbus0 at ahc0 # Single bus device
687# controller scbus1 at ahc1 bus 0 # Single bus device
688# controller scbus3 at ahc2 bus 0 # Twin bus device
689# controller scbus2 at ahc2 bus 1 # Twin bus device
690# disk da0 at scbus0 target 0 unit 0
691# disk da1 at scbus3 target 1
692# disk da2 at scbus2 target 3
693# tape st1 at scbus1 target 6
694# device cd0 at scbus?
695
696# "units" (SCSI logical unit number) that are not specified are
697# treated as if specified as LUN 0.
698
699# All SCSI devices allocate as many units as are required.

974# 0x02 don't use the npx registers to optimize bzero
975# 0x04 don't use the npx registers to optimize copyin or copyout.
976# The npx registers are normally used to optimize copying and zeroing when
977# all of the following conditions are satisfied:
978# "I586_CPU" is an option
979# the cpu is an i586 (perhaps not a Pentium)
980# the probe for npx0 succeeds
981# INT 16 exception handling works.
982# Then copying and zeroing using the npx registers is normally 30-100% faster.
983# The flags can be used to control cases where it doesn't work or is slower.
984# Setting them at boot time using userconfig works right (the optimizations
985# are not used until later in the bootstrap when npx0 is attached).

1041# ST-506, ESDI, and IDE hard disks: `wdc' and `wd'
1042#
1043# The flags fields are used to enable the multi-sector I/O and
1044# the 32BIT I/O modes. The flags may be used in either the controller
1045# definition or in the individual disk definitions. The controller
1046# definition is supported for the boot configuration stuff.
1047#
1048# Each drive has a 16 bit flags value defined:
1049# The low 8 bits are the maximum value for the multi-sector I/O,
1050# where 0xff defaults to the maximum that the drive can handle.
1051# The high bit of the 16 bit flags (0x8000) allows probing for
1052# 32 bit transfers. Bit 14 (0x4000) enables a hack to wake
1053# up powered-down laptop drives. Bit 13 (0x2000) allows
1054# probing for PCI IDE DMA controllers, such as Intel's PIIX
1055# south bridges. Bit 12 (0x1000) sets LBA mode instead of the
1056# default CHS mode for accessing the drive. See the wd.4 man page.
1057#
1058# The flags field for the drives can be specified in the controller
1059# specification with the low 16 bits for drive 0, and the high 16 bits
1060# for drive 1.
1061# e.g.:
1062#controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004
1063#
1064# specifies that drive 0 will be allowed to probe for 32 bit transfers and
1065# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
1066# allowed to probe for 32 bit transfers, but will allow multi-sector
1067# transfers up to the maximum that the drive supports.
1068#
1069# If you are using a PCI controller that is not running in compatibility
1070# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
1071# such as:
1072#
1073#controller wdc2 at isa? port "0" bio irq ? flags 0xa0ffa0ff

1407# If instead you have two ISA cards, one installed at 0x100 and the
1408# second installed at 0x180, then you should add the following to
1409# your kernel configuration file:
1410#
1411# device rp0 at isa? port 0x100 tty
1412# device rp1 at isa? port 0x180 tty
1413#
1414# For 4 ISA cards, it might be something like this:
1415#
1416# device rp0 at isa? port 0x180 tty
1417# device rp1 at isa? port 0x100 tty
1418# device rp2 at isa? port 0x340 tty
1419# device rp3 at isa? port 0x240 tty
1420#
1421# And for PCI cards, you only need say:
1422#
1423# device rp0
1424# device rp1
1425# ...
1426# Note: Make sure that any Rocketport PCI devices are specified BEFORE the
1427# ISA Rocketport devices.

1429# Notes on the Digiboard driver:
1430#
1431# The following flag values have special meanings:
1432# 0x01 - alternate layout of pins (dgb & dgm)
1433# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1434
1435# Notes on the Specialix SI/XIO driver:
1436# **This is NOT a Specialix supported Driver!**
1437# The host card is memory, not IO mapped.
1438# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1439# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1440# The cards can use an IRQ of 11, 12 or 15.

1442# Notes on the Stallion stl and stli drivers:
1443# See src/i386/isa/README.stl for complete instructions.
1444# This is version 0.0.5alpha, unsupported by Stallion.
1445# The stl driver has a secondary IO port hard coded at 0x280. You need
1446# to change src/i386/isa/stallion.c if you reconfigure this on the boards.
1447# The "flags" and "iosiz" settings on the stli driver depend on the board:
1448# EasyConnection 8/64 ISA: flags 23 iosiz 0x1000
1449# EasyConnection 8/64 EISA: flags 24 iosiz 0x10000

1535# FC/AL Host Adapter.
