533
534# SCSI DEVICE CONFIGURATION
535
536# The SCSI subsystem consists of the `base' SCSI code, a number of
537# high-level SCSI device `type' drivers, and the low-level host-adapter
538# device drivers. The host adapters are listed in the ISA and PCI
539# device configuration sections below.
540#
541# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
542# that a given bus, target, and LUN always come on line as the same
543# device unit. In earlier versions the unit numbers were assigned
544# in the order that the devices were probed on the SCSI bus. This
545# means that if you removed a disk drive, you may have had to rewrite
546# your /etc/fstab file, and also that you had to be careful when adding
547# a new disk as it may have been probed earlier and moved your device
548# configuration around.
549
550# This old behavior is maintained as the default behavior. The unit
551# assignment begins with the first non-wired down unit for a device
552# type. For example, if you wire a disk as "sd3" then the first
553# non-wired disk will be assigned sd4.
554
555# The syntax for wiring down devices is:
556
557# controller scbus0 at ahc0 # Single bus device

534# SCSI DEVICE CONFIGURATION
535
536# The SCSI subsystem consists of the `base' SCSI code, a number of
537# high-level SCSI device `type' drivers, and the low-level host-adapter
538# device drivers. The host adapters are listed in the ISA and PCI
539# device configuration sections below.
540#
541# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
542# that a given bus, target, and LUN always come on line as the same
543# device unit. In earlier versions the unit numbers were assigned
544# in the order that the devices were probed on the SCSI bus. This
545# means that if you removed a disk drive, you may have had to rewrite
546# your /etc/fstab file, and also that you had to be careful when adding
547# a new disk as it may have been probed earlier and moved your device
548# configuration around.
549
550# This old behavior is maintained as the default behavior. The unit
551# assignment begins with the first non-wired down unit for a device
552# type. For example, if you wire a disk as "sd3" then the first
553# non-wired disk will be assigned sd4.
554
555# The syntax for wiring down devices is:
556
557# controller scbus0 at ahc0 # Single bus device
558# controller scbus1 at ahc1 bus 0 # Single bus device
559# controller scbus3 at ahc2 bus 0 # Twin bus device
560# controller scbus2 at ahc2 bus 1 # Twin bus device
561# disk sd0 at scbus0 target 0 unit 0
562# disk sd1 at scbus3 target 1

658# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
659# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
660# This option breaks suspend/resume on some portables.
661#
662# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
663# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
664# Automatic EOI is documented not to work for for the slave with the
665# original i8259A, but it works for some clones and some integrated

668# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
669# than 16 megabytes of memory. It doesn't hurt on other machines.
670# Some broken EISA and VLB hardware may need this, too.
671#
672# MAXMEM specifies the amount of RAM on the machine; if this is not
673# specified, FreeBSD will first read the amount of memory from the CMOS
674# RAM, so the amount of memory will initially be limited to 64MB or 16MB
675# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
676# then attempt to detect the installed amount of RAM. If this probe
677# fails to detect >64MB RAM you will have to use the MAXMEM option.
678# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

829# allowed to probe for 32 bit transfers, but will allow multi-sector
830# transfers up to the maximum that the drive supports.
831#
832# If you are using a PCI controller that is not running in compatibility

1160# your kernel configuration file:
1161#
1162# device rp0 at isa? port 0x100 tty
1163# device rp1 at isa? port 0x180 tty

1492# DPT_VERIFY_HINTR Performs some strict hardware interrupts testing.
1493# Only use if you suspect PCI bus corruption problems
1494# DPT_RESTRICTED_FREELIST Normally, the freelisat used by the DPT for queue

1496# will NOT shrink. To restrict the number of queue
1497# slots to exactly what the DPT can hold at one time,
1498# enable this option.
1499# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1500# instruments are enabled. Assumed to be enabled by
1501# /usr/sbin/dpt_* tools.
1502# DPT_FREELIST_IS_STACK For optimat L{1,2} CPU cache utilization, enable
1503# this option. Otherwise, the transaction queue is
1504# a LIFO. I cannot measure the performance gain.
1505# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1506# If you ant the driver to handle timeouts, enable
1507# this option. If your system is very busy, this
1508# option will create more trouble than solve.

666controller isa0

668#
669# Options for `isa':
670#
671# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
672# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
673# This option breaks suspend/resume on some portables.
674#
675# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
676# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
677# Automatic EOI is documented not to work for for the slave with the
678# original i8259A, but it works for some clones and some integrated
679# versions.
680#
681# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
682# than 16 megabytes of memory. It doesn't hurt on other machines.
683# Some broken EISA and VLB hardware may need this, too.
684#
685# MAXMEM specifies the amount of RAM on the machine; if this is not
686# specified, FreeBSD will first read the amount of memory from the CMOS
687# RAM, so the amount of memory will initially be limited to 64MB or 16MB
688# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
689# then attempt to detect the installed amount of RAM. If this probe
690# fails to detect >64MB RAM you will have to use the MAXMEM option.
691# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
692# be 131072 (128 * 1024).
693#
694# TUNE_1542 enables the automatic ISA bus speed selection for the
695# Adaptec 1542 boards. Does not work for all boards, use it with caution.
696#
697# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to

820# The flags fields are used to enable the multi-sector I/O and

822# definition or in the individual disk definitions. The controller
823# definition is supported for the boot configuration stuff.
824#
825# Each drive has a 16 bit flags value defined:
826# The low 8 bits are the maximum value for the multi-sector I/O,
827# where 0xff defaults to the maximum that the drive can handle.
828# The high bit of the 16 bit flags (0x8000) allows probing for
829# 32 bit transfers. Bit 14 (0x4000) enables a hack to wake
830# up powered-down laptop drives. Bit 13 (0x2000) allows
831# probing for PCI IDE DMA controllers, such as Intel's PIIX
832# south bridges. See the wd.4 man page.
833#
834# The flags field for the drives can be specified in the controller
835# specification with the low 16 bits for drive 0, and the high 16 bits
836# for drive 1.
837# e.g.:
838#controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004 vector wdintr
839#
840# specifies that drive 0 will be allowed to probe for 32 bit transfers and
841# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
842# allowed to probe for 32 bit transfers, but will allow multi-sector
843# transfers up to the maximum that the drive supports.
844#
845# If you are using a PCI controller that is not running in compatibility
846# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)
847# such as:
848#
849#controller wdc2 at isa? port "0" bio irq ? flags 0xa0ffa0ff vector wdintr

1173# your kernel configuration file:
1174#
1175# device rp0 at isa? port 0x100 tty
1176# device rp1 at isa? port 0x180 tty
1177#
1178# For 4 ISA cards, it might be something like this:

1182# device rp2 at isa? port 0x340 tty
1183# device rp3 at isa? port 0x240 tty
1184#
1185# And for PCI cards, you only need say:
1186#

1502# The 'dpt' driver provides support for DPT controllers (http://www.dpt.com/).
1503# These have hardware RAID-{0,1,5} support, and do multi-initiator I/O.
1504# See sys/dev/dpt for debugging and other subtle options.
1505# DPT_VERIFY_HINTR Performs some strict hardware interrupts testing.
1506# Only use if you suspect PCI bus corruption problems
1507# DPT_RESTRICTED_FREELIST Normally, the freelisat used by the DPT for queue
1508# will grow to accomodate increased use. This growth
1509# will NOT shrink. To restrict the number of queue
1510# slots to exactly what the DPT can hold at one time,
1511# enable this option.
1512# DPT_MEASURE_PERFORMANCE Enables a set of (semi)invasive metrics. Various
1513# instruments are enabled. Assumed to be enabled by
1514# /usr/sbin/dpt_* tools.
1515# DPT_FREELIST_IS_STACK For optimat L{1,2} CPU cache utilization, enable
1516# this option. Otherwise, the transaction queue is
1517# a LIFO. I cannot measure the performance gain.
1518# DPT_HANDLE_TIMEOUTS Normally device timeouts are handled by the DPT.
1519# If you ant the driver to handle timeouts, enable
1520# this option. If your system is very busy, this
1521# option will create more trouble than solve.
1522# DPT_TIMEOUT_FACTOR Used to compute the excessive amount of time to
1523# wait when timing out with the above option.
1524# DPT_DEBUG_xxxx These are controllable from sys/dev/dpt/dpt.h
1525# DPT_LOST_IRQ When enabled, will try, once per second, to catch
1526# any interrupt that got lost. Seems to help in some
1527# DPT-firmware/Motherboard combinations. Minimal
1528# cost, great benefit.
