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 formula defined in subr_param.c. Setting
33 # maxusers to 0 will cause the system to auto-size based on physical
39 # We want LINT to cover profiling as well
43 # The `makeoptions' parameter allows variables to be passed to the

51 # The following is equivalent to 'config -g KERNELNAME' and creates

854 # SCSI DEVICE CONFIGURATION
856 # The SCSI subsystem consists of the `base' SCSI code, a number of
857 # high-level SCSI device `type' drivers, and the low-level host-adapter
858 # device drivers. The host adapters are listed in the ISA and PCI
859 # device configuration sections below.
861 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
862 # that a given bus, target, and LUN always come on line as the same
863 # device unit. In earlier versions the unit numbers were assigned
864 # in the order that the devices were probed on the SCSI bus. This
865 # means that if you removed a disk drive, you may have had to rewrite
866 # your /etc/fstab file, and also that you had to be careful when adding
867 # a new disk as it may have been probed earlier and moved your device
868 # configuration around.
870 # This old behavior is maintained as the default behavior. The unit
871 # assignment begins with the first non-wired down unit for a device
872 # type. For example, if you wire a disk as "da3" then the first
873 # non-wired disk will be assigned da4.
875 # The syntax for wiring down devices is:
877 hint.scbus.0.at="ahc0"
878 hint.scbus.1.at="ahc1"
880 hint.scbus.3.at="ahc2"

2119 # registers to map it in, even though it is otherwise treated here as
2120 # an ISA device. At the moment, the driver polls, although the device
2121 # is capable of generating interrupts. It largely undocumented.
2122 # The port location in the hint is where you WANT the device to be
2123 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2124 # is the only thing truly supported, but aparently a fair percentage
