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

904 # SCSI DEVICE CONFIGURATION
906 # The SCSI subsystem consists of the `base' SCSI code, a number of
907 # high-level SCSI device `type' drivers, and the low-level host-adapter
908 # device drivers. The host adapters are listed in the ISA and PCI
909 # device configuration sections below.
911 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
912 # that a given bus, target, and LUN always come on line as the same
913 # device unit. In earlier versions the unit numbers were assigned
914 # in the order that the devices were probed on the SCSI bus. This
915 # means that if you removed a disk drive, you may have had to rewrite
916 # your /etc/fstab file, and also that you had to be careful when adding
917 # a new disk as it may have been probed earlier and moved your device
918 # configuration around.
920 # This old behavior is maintained as the default behavior. The unit
921 # assignment begins with the first non-wired down unit for a device
922 # type. For example, if you wire a disk as "da3" then the first
923 # non-wired disk will be assigned da4.
925 # The syntax for wiring down devices is:

2190 # This is a temporary driver that should someday be replaced by something
2191 # that hooks into the ACPI layer. The device is hooked to the PIIX4's
2192 # General Device 10 decoder, which means you have to fiddle with PCI
2193 # registers to map it in, even though it is otherwise treated here as
2194 # an ISA device. At the moment, the driver polls, although the device
2195 # is capable of generating interrupts. It largely undocumented.
2196 # The port location in the hint is where you WANT the device to be
2197 # mapped. 0x10a0 seems to be traditional. At the moment the jogdial
2198 # is the only thing truly supported, but aparently a fair percentage
2199 # of the Vaio extra features are controlled by this device.
