11 # Please use ``make LINT'' to create an old-style LINT file if you want to

18 # This directive is mandatory; it defines the architecture to be
19 # configured for; in this case, the 386 family based IBM-PC and
25 # This is the ``identification'' of the kernel. Usually this should
26 # be the same as the name of your kernel.
31 # The `maxusers' parameter controls the static sizing of a number of
32 # internal system tables by a complicated formula defined in param.c.
37 # We want LINT to cover profiling as well
41 # The `makeoptions' parameter allows variables to be passed to the
42 # generated Makefile in the build area.

45 # after most other flags. Here we use it to inhibit use of non-optimal

49 # The following is equivalent to 'config -g KERNELNAME' and creates
50 # 'kernel.debug' compiled with -g debugging as well as a normal
51 # 'kernel'. Use 'make install.debug' to install the debug kernel
52 # but that isn't normally necessary as the debug symbols are not loaded

800 # SCSI DEVICE CONFIGURATION
802 # The SCSI subsystem consists of the `base' SCSI code, a number of
803 # high-level SCSI device `type' drivers, and the low-level host-adapter
804 # device drivers. The host adapters are listed in the ISA and PCI
805 # device configuration sections below.
807 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
808 # that a given bus, target, and LUN always come on line as the same
809 # device unit. In earlier versions the unit numbers were assigned
810 # in the order that the devices were probed on the SCSI bus. This
811 # means that if you removed a disk drive, you may have had to rewrite
812 # your /etc/fstab file, and also that you had to be careful when adding
813 # a new disk as it may have been probed earlier and moved your device
814 # configuration around.
816 # This old behavior is maintained as the default behavior. The unit
817 # assignment begins with the first non-wired down unit for a device
818 # type. For example, if you wire a disk as "da3" then the first
819 # non-wired disk will be assigned da4.
821 # The syntax for wiring down devices is:
823 hint.scbus.0.at="ahc0"
824 hint.scbus.1.at="ahc1"
826 hint.scbus.3.at="ahc2"

841 # treated as if specified as LUN 0.

847 # The da driver drives SCSI Direct Access ("disk") and Optical Media
850 # The sa driver drives SCSI Sequential Access ("tape") devices.
852 # The cd driver drives SCSI Read Only Direct Access ("cd") devices.
854 # The ses driver drives SCSI Envinronment Services ("ses") and
855 # SAF-TE ("SCSI Accessable Fault-Tolerant Enclosure") devices.
857 # The pt driver drives SCSI Processor devices.
860 # Target Mode support is provided here but also requires that a SIM
861 # (SCSI Host Adapter Driver) provide support as well.
863 # The targ driver provides target mode support as a Processor type device.
864 # It exists to give the minimal context necessary to respond to Inquiry
865 # commands. There is a sample user application that shows how the rest
866 # of the command support might be done in /usr/share/examples/scsi_target.

869 # to incoming commands that do not otherwise have a logical unit assigned

1978 # 0x01 - alternate layout of pins (dgb & dgm)
1979 # 0x02 - use the windowed PC/Xe in 64K mode (dgb only)
1981 # Notes on the Specialix SI/XIO driver:
1982 # The host card is memory, not IO mapped.
1983 # The Rev 1 host cards use a 64K chunk, on a 32K boundary.
1984 # The Rev 2 host cards use a 32K chunk, on a 32K boundary.
1985 # The cards can use an IRQ of 11, 12 or 15.
1987 # Notes on the Sony Programmable I/O controller
1988 # This is a temporary driver that should someday be replaced by something
1989 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
1990 # General Device 10 decoder, which means you have to fiddle with PCI
1991 # registers to map it in, even though it is otherwise treated here as
1992 # an ISA device. At the moment, the driver polls, although the device
1993 # is capable of generating interrupts. It largely undocumented.
1994 # The port location in the hint is where you WANT the device to be
1995 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
1996 # is the only thing truly supported, but aparently a fair percentage
1997 # of the Vaio extra features are controlled by this device.
1999 # Notes on the Stallion stl and stli drivers:

2001 # This is version 0.0.5alpha, unsupported by Stallion.
2002 # The stl driver has a secondary IO port hard coded at 0x280. You need
