576# SCSI DEVICE CONFIGURATION
577
578# The SCSI subsystem consists of the `base' SCSI code, a number of
579# high-level SCSI device `type' drivers, and the low-level host-adapter
580# device drivers. The host adapters are listed in the ISA and PCI
581# device configuration sections below.
582#
583# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
584# that a given bus, target, and LUN always come on line as the same
585# device unit. In earlier versions the unit numbers were assigned
586# in the order that the devices were probed on the SCSI bus. This
587# means that if you removed a disk drive, you may have had to rewrite
588# your /etc/fstab file, and also that you had to be careful when adding
589# a new disk as it may have been probed earlier and moved your device
590# configuration around.
591
592# This old behavior is maintained as the default behavior. The unit
593# assignment begins with the first non-wired down unit for a device
594# type. For example, if you wire a disk as "sd3" then the first
595# non-wired disk will be assigned sd4.
596
597# The syntax for wiring down devices is:
598
599# controller scbus0 at ahc0 # Single bus device
600# controller scbus1 at ahc1 bus 0 # Single bus device
601# controller scbus3 at ahc2 bus 0 # Twin bus device
602# controller scbus2 at ahc2 bus 1 # Twin bus device
603# disk sd0 at scbus0 target 0 unit 0
604# disk sd1 at scbus3 target 1
605# disk sd2 at scbus2 target 3
606# tape st1 at scbus1 target 6
607# device cd0 at scbus?

702#
703# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
704# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
705# This option breaks suspend/resume on some portables.
706#
707# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
708# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
709# Automatic EOI is documented not to work for for the slave with the
710# original i8259A, but it works for some clones and some integrated
711# versions.
712#
713# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
714# than 16 megabytes of memory. It doesn't hurt on other machines.
715# Some broken EISA and VLB hardware may need this, too.
716#
717# MAXMEM specifies the amount of RAM on the machine; if this is not
718# specified, FreeBSD will first read the amount of memory from the CMOS
719# RAM, so the amount of memory will initially be limited to 64MB or 16MB
720# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
721# then attempt to detect the installed amount of RAM. If this probe
722# fails to detect >64MB RAM you will have to use the MAXMEM option.
723# The amount is in kilobytes, so for a machine with 128MB of RAM, it would

859#
860# Each drive has a 16 bit flags value defined:

862# where 0xff defaults to the maximum that the drive can handle.
863# The high bit of the 16 bit flags (0x8000) allows probing for
864# 32 bit transfers. Bit 14 (0x4000) enables a hack to wake
865# up powered-down laptop drives. Bit 13 (0x2000) allows
866# probing for PCI IDE DMA controllers, such as Intel's PIIX
867# south bridges. Bit 12 (0x1000) sets LBA mode instead of the
868# default CHS mode for accessing the drive. See the wd.4 man page.
869#
870# The flags field for the drives can be specified in the controller
871# specification with the low 16 bits for drive 0, and the high 16 bits
872# for drive 1.
873# e.g.:
874#controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004 vector wdintr
875#
876# specifies that drive 0 will be allowed to probe for 32 bit transfers and
877# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
878# allowed to probe for 32 bit transfers, but will allow multi-sector
879# transfers up to the maximum that the drive supports.
880#
881# If you are using a PCI controller that is not running in compatibility
882# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)

1222# device rp0 at isa? port 0x100 tty
1223# device rp1 at isa? port 0x180 tty

1229# device rp2 at isa? port 0x340 tty
1230# device rp3 at isa? port 0x240 tty

576# SCSI DEVICE CONFIGURATION
577
578# The SCSI subsystem consists of the `base' SCSI code, a number of
579# high-level SCSI device `type' drivers, and the low-level host-adapter
580# device drivers. The host adapters are listed in the ISA and PCI
581# device configuration sections below.
582#
583# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
584# that a given bus, target, and LUN always come on line as the same
585# device unit. In earlier versions the unit numbers were assigned
586# in the order that the devices were probed on the SCSI bus. This
587# means that if you removed a disk drive, you may have had to rewrite
588# your /etc/fstab file, and also that you had to be careful when adding
589# a new disk as it may have been probed earlier and moved your device
590# configuration around.
591
592# This old behavior is maintained as the default behavior. The unit
593# assignment begins with the first non-wired down unit for a device
594# type. For example, if you wire a disk as "sd3" then the first
595# non-wired disk will be assigned sd4.
596
597# The syntax for wiring down devices is:
598
599# controller scbus0 at ahc0 # Single bus device
600# controller scbus1 at ahc1 bus 0 # Single bus device
601# controller scbus3 at ahc2 bus 0 # Twin bus device
602# controller scbus2 at ahc2 bus 1 # Twin bus device
603# disk sd0 at scbus0 target 0 unit 0
604# disk sd1 at scbus3 target 1
605# disk sd2 at scbus2 target 3
606# tape st1 at scbus1 target 6
607# device cd0 at scbus?
608
609# "units" (SCSI logical unit number) that are not specified are
610# treated as if specified as LUN 0.
611
612# All SCSI devices allocate as many units as are required.

701# Options for `isa':
702#
703# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
704# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
705# This option breaks suspend/resume on some portables.
706#
707# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
708# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
709# Automatic EOI is documented not to work for for the slave with the
710# original i8259A, but it works for some clones and some integrated
711# versions.
712#
713# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
714# than 16 megabytes of memory. It doesn't hurt on other machines.
715# Some broken EISA and VLB hardware may need this, too.
716#
717# MAXMEM specifies the amount of RAM on the machine; if this is not
718# specified, FreeBSD will first read the amount of memory from the CMOS
719# RAM, so the amount of memory will initially be limited to 64MB or 16MB
720# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
721# then attempt to detect the installed amount of RAM. If this probe
722# fails to detect >64MB RAM you will have to use the MAXMEM option.
723# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
724# be 131072 (128 * 1024).

859#
860# Each drive has a 16 bit flags value defined:
861# The low 8 bits are the maximum value for the multi-sector I/O,
862# where 0xff defaults to the maximum that the drive can handle.
863# The high bit of the 16 bit flags (0x8000) allows probing for
864# 32 bit transfers. Bit 14 (0x4000) enables a hack to wake
865# up powered-down laptop drives. Bit 13 (0x2000) allows
866# probing for PCI IDE DMA controllers, such as Intel's PIIX
867# south bridges. Bit 12 (0x1000) sets LBA mode instead of the
868# default CHS mode for accessing the drive. See the wd.4 man page.
869#
870# The flags field for the drives can be specified in the controller
871# specification with the low 16 bits for drive 0, and the high 16 bits
872# for drive 1.
873# e.g.:
874#controller wdc0 at isa? port "IO_WD1" bio irq 14 flags 0x00ff8004 vector wdintr
875#
876# specifies that drive 0 will be allowed to probe for 32 bit transfers and
877# a maximum multi-sector transfer of 4 sectors, and drive 1 will not be
878# allowed to probe for 32 bit transfers, but will allow multi-sector
879# transfers up to the maximum that the drive supports.
880#
881# If you are using a PCI controller that is not running in compatibility
882# mode (for example, it is a 2nd IDE PCI interface), then use config line(s)

1214#
1215# Comtrol Rocketport ISA single card

1217#
1218# If instead you have two ISA cards, one installed at 0x100 and the
1219# second installed at 0x180, then you should add the following to
1220# your kernel configuration file:
1221#
1222# device rp0 at isa? port 0x100 tty
1223# device rp1 at isa? port 0x180 tty
1224#
1225# For 4 ISA cards, it might be something like this:

1228# device rp1 at isa? port 0x100 tty
1229# device rp2 at isa? port 0x340 tty
1230# device rp3 at isa? port 0x240 tty
1231#
1232# And for PCI cards, you only need say:
1233#
1234# device rp0
1235# device rp1
1236# ...
1237# Note: Make sure that any Rocketport PCI devices are specified BEFORE the

1240# Notes on the Digiboard driver:
1241#

1243# 0x01 - alternate layout of pins (dgb & dgm)
1244# 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1245
1246# Notes on the Specialix SI/XIO driver:
1247# **This is NOT a Specialix supported Driver!**
1248# The host card is memory, not IO mapped.
1249# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
