459
460# SCSI DEVICE CONFIGURATION
461
462# The SCSI subsystem consists of the `base' SCSI code, a number of
463# high-level SCSI device `type' drivers, and the low-level host-adapter
464# device drivers. The host adapters are listed in the ISA and PCI
465# device configuration sections below.
466#
467# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
468# that a given bus, target, and LUN always come on line as the same
469# device unit. In earlier versions the unit numbers were assigned
470# in the order that the devices were probed on the SCSI bus. This
471# means that if you removed a disk drive, you may have had to rewrite
472# your /etc/fstab file, and also that you had to be careful when adding
473# a new disk as it may have been probed earlier and moved your device
474# configuration around.
475
476# This old behavior is maintained as the default behavior. The unit
477# assignment begins with the first non-wired down unit for a device
478# type. For example, if you wire a disk as "sd3" then the first
479# non-wired disk will be assigned sd4.
480
481# The syntax for wiring down devices is:
482
483# controller scbus0 at ahc0 # Single bus device
484# controller scbus1 at ahc1 bus 0 # Single bus device
485# controller scbus3 at ahc2 bus 0 # Twin bus device
486# controller scbus2 at ahc2 bus 1 # Twin bus device

590# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
591# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
592# This option breaks suspend/resume on some portables.
593#
594# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
595# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
596# Automatic EOI is documented not to work for for the slave with the
597# original i8259A, but it works for some clones and some integrated
598# versions.
599#
600# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
601# than 16 megabytes of memory. It doesn't hurt on other machines.
602# Some broken EISA and VLB hardware may need this, too.
603#
604# MAXMEM specifies the amount of RAM on the machine; if this is not
605# specified, FreeBSD will read the amount of memory from the CMOS RAM,
606# so the amount of memory will be limited to 64MB or 16MB depending on
607# the BIOS. The amount is in kilobytes, so for a machine with 128MB of
608# RAM, it would be 131072 (128 * 1024).
609#
610# TUNE_1542 enables the automatic ISA bus speed selection for the
611# Adaptec 1542 boards. Does not work for all boards, use it with caution.

458# SCSI DEVICES
459
460# SCSI DEVICE CONFIGURATION
461
462# The SCSI subsystem consists of the `base' SCSI code, a number of
463# high-level SCSI device `type' drivers, and the low-level host-adapter
464# device drivers. The host adapters are listed in the ISA and PCI
465# device configuration sections below.
466#
467# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
468# that a given bus, target, and LUN always come on line as the same
469# device unit. In earlier versions the unit numbers were assigned
470# in the order that the devices were probed on the SCSI bus. This
471# means that if you removed a disk drive, you may have had to rewrite
472# your /etc/fstab file, and also that you had to be careful when adding
473# a new disk as it may have been probed earlier and moved your device
474# configuration around.
475
476# This old behavior is maintained as the default behavior. The unit
477# assignment begins with the first non-wired down unit for a device
478# type. For example, if you wire a disk as "sd3" then the first
479# non-wired disk will be assigned sd4.
480
481# The syntax for wiring down devices is:
482
483# controller scbus0 at ahc0 # Single bus device
484# controller scbus1 at ahc1 bus 0 # Single bus device
485# controller scbus3 at ahc2 bus 0 # Twin bus device
486# controller scbus2 at ahc2 bus 1 # Twin bus device
487# disk sd0 at scbus0 target 0 unit 0
488# disk sd1 at scbus3 target 1
489# disk sd2 at scbus2 target 3
490# tape st1 at scbus1 target 6
491# device cd0 at scbus?
492
493# "units" (SCSI logical unit number) that are not specified are
494# treated as if specified as LUN 0.
495
496# All SCSI devices allocate as many units as are required.
497
498# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI

578# ISA and EISA devices:
579# EISA support is available for some device, so they can be auto-probed.
580# Micro Channel is not supported at all.
581
582#
583# Mandatory ISA devices: isa, sc or vt, npx
584#
585controller isa0
586
587#
588# Options for `isa':
589#
590# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
591# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
592# This option breaks suspend/resume on some portables.
593#
594# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
595# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
596# Automatic EOI is documented not to work for for the slave with the
597# original i8259A, but it works for some clones and some integrated
598# versions.
599#
600# BOUNCE_BUFFERS provides support for ISA DMA on machines with more
601# than 16 megabytes of memory. It doesn't hurt on other machines.
602# Some broken EISA and VLB hardware may need this, too.
603#
604# MAXMEM specifies the amount of RAM on the machine; if this is not
605# specified, FreeBSD will read the amount of memory from the CMOS RAM,
606# so the amount of memory will be limited to 64MB or 16MB depending on
607# the BIOS. The amount is in kilobytes, so for a machine with 128MB of
608# RAM, it would be 131072 (128 * 1024).
609#
610# TUNE_1542 enables the automatic ISA bus speed selection for the
611# Adaptec 1542 boards. Does not work for all boards, use it with caution.
612#
613# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
614# reset the CPU for reboot. This is needed on some systems with broken

666# the cpu is an i586 (perhaps not a Pentium)
667# the probe for npx0 succeeds
668# INT 16 exception handling works.
669# Then copying and zeroing using the npx registers is normally 30-100% faster.
670# The flags can be used to control cases where it doesn't work or is slower.

679# size reported by the BIOS. Setting it at boot time using userconfig takes
