freebsd-skq/sys/i386/conf/NOTES
wollman 9e6f88883f Finally demolished the last, tottering remnants of GATEWAY. If you want
to enable IP forwarding, use sysctl(8).  Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.
(The two should never have been controlled by the same option anyway.)

# SCSI DEVICES
# SCSI DEVICE CONFIGURATION
# The SCSI subsystem consists of the `base' SCSI code, a number of
# high-level SCSI device `type' drivers, and the low-level host-adapter
# device drivers. The host adapters are listed in the ISA and PCI
# device configuration sections below.
#
# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
# that a given bus, target, and LUN always come on line as the same
# device unit. In earlier versions the unit numbers were assigned
# in the order that the devices were probed on the SCSI bus. This
# means that if you removed a disk drive, you may have had to rewrite
# your /etc/fstab file, and also that you had to be careful when adding
# a new disk as it may have been probed earlier and moved your device
# configuration around.
# This old behavior is maintained as the default behavior. The unit
# assignment begins with the first non-wired down unit for a device
# type. For example, if you wire a disk as "sd3" then the first
# non-wired disk will be assigned sd4.
# The syntax for wiring down devices is:
# controller scbus0 at ahc0 # Single bus device
# controller scbus1 at ahc1 bus 0 # Single bus device
# controller scbus3 at ahc2 bus 0 # Twin bus device
# controller scbus2 at ahc2 bus 1 # Twin bus device
# disk sd0 at scbus0 target 0 unit 0
# disk sd1 at scbus3 target 1
# disk sd2 at scbus2 target 3
# tape st1 at scbus1 target 6
# device cd0 at scbus?
# "units" (SCSI logical unit number) that are not specified are
# treated as if specified as LUN 0.
# All SCSI devices allocate as many units as are required.
# The "unknown" device (uk? in pre-2.0.5) is now part of the base SCSI
# configuration and doesn't have to be explicitly configured.
controller scbus0 #base SCSI code
device ch0 #SCSI media changers
device sd0 #SCSI disks
device st0 #SCSI tapes
device cd0 #SCSI CD-ROMs
device od0 #SCSI optical disk
# The previous devices (ch, sd, st, cd) are recognized by config.
# config doesn't (and shouldn't) know about these newer ones,
# so we have to specify that they are on a SCSI bus with the "at scbus?"
# clause.
device worm0 at scbus? # SCSI worm
device pt0 at scbus? # SCSI processor type
device sctarg0 at scbus? # SCSI target
# SCSI OPTIONS:
# SCSIDEBUG: When defined enables debugging macros
# NO_SCSI_SENSE: When defined disables sense descriptions (about 4k)
# SCSI_REPORT_GEOMETRY: Always report disk geometry at boot up instead
# of only when booting verbosely.

# DUMMY_NOPS disables extra delays for some bus operations. The delays

#
# TUNE_1542 enables the automatic ISA bus speed selection for the
# Adaptec 1542 boards. Does not work for all boards, use it with caution.

# Each drive has a 16 bit flags value defined:

#
# Notes on the spigot:
# The video spigot is at 0xad6. This port address can not be changed.
# The irq values may only be 10, 11, or 15
# I/O memory is an 8kb region. Possible values are:
# 0a0000, 0a2000, ..., 0fffff, f00000, f02000, ..., ffffff
# The start address must be on an even boundary.
# Add the following option if you want to allow non-root users to be able
# to access the spigot. This option is not secure because it allows users
# direct access to the I/O page.
# options SPIGOT_UNSECURE
#
# Notes on the Digiboard driver:
#
# The following flag values have special meanings:
# 0x01 - alternate layout of pins
# 0x02 - use the windowed PC/Xe in 64K mode
# Notes on the Specialix SI/XIO driver:
# **This is NOT a Specialix supported Driver!**
# The host card is memory, not IO mapped.
# The Rev 1 host cards use a 64K chunk, on a 32K boundary.
# The Rev 2 host cards use a 32K chunk, on a 32K boundary.
# The cards can use an IRQ of 11, 12 or 15.

# EISA devices:
#
# The EISA bus device is eisa0. It provides auto-detection and
# configuration support for all devices on the EISA bus.
#
# The `ahb' device provides support for the Adaptec 174X adapter.
#
# The `ahc' device provides support for the Adaptec 274X and 284X
# adapters. The 284X, although a VLB card responds to EISA probes.

# PCI devices:
#
# The main PCI bus device is `pci'. It provides auto-detection and
# configuration support for all devices on the PCI bus, using either
# configuration mode defined in the PCI specification.
#
# The `ahc' device provides support for the Adaptec 29/3940(U)(W)
# and motherboard based AIC7870/AIC7880 adapters.
#
# The `ncr' device provides support for the NCR 53C810 and 53C825
# self-contained SCSI host adapters.
#
# The `de' device provides support for the Digital Equipment DC21040
# self-contained Ethernet adapter.
#
# The `vx' device provides support for the 3Com 3C590
# early support
#
# The `fpa' device provides support for the Digital DEFPA PCI FDDI
# adapter. pseudo-device fddi is also needed.
#
# The PROBE_VERBOSE option enables a long listing of chip set registers
# for supported PCI chip sets (currently only intel Saturn and Mercury).
#
# The 'meteor' device is a PCI video capture board. It can also have the
# following options:
# options METEOR_ALLOC_PAGES=xxx preallocate kernel pages for data entry
# figure (ROWS*COLUMN*BYTES_PER_PIXEL*FRAME+PAGE_SIZE-1)/PAGE_SIZE
# options METEOR_DEALLOC_PAGES remove all allocated pages on close(2)
# options METEOR_DEALLOC_ABOVE=xxx remove all allocated pages above the
# specified amount. If this value is below the allocated amount no action
# taken
