880# SCSI DEVICE CONFIGURATION
881
882# The SCSI subsystem consists of the `base' SCSI code, a number of
883# high-level SCSI device `type' drivers, and the low-level host-adapter
884# device drivers. The host adapters are listed in the ISA and PCI
885# device configuration sections below.
886#
887# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
888# that a given bus, target, and LUN always come on line as the same
889# device unit. In earlier versions the unit numbers were assigned
890# in the order that the devices were probed on the SCSI bus. This
891# means that if you removed a disk drive, you may have had to rewrite
892# your /etc/fstab file, and also that you had to be careful when adding
893# a new disk as it may have been probed earlier and moved your device
894# configuration around.
895
896# This old behavior is maintained as the default behavior. The unit
897# assignment begins with the first non-wired down unit for a device
898# type. For example, if you wire a disk as "da3" then the first
899# non-wired disk will be assigned da4.
900
901# The syntax for wiring down devices is:
902
903# device scbus0 at ahc0 # Single bus device
904# device scbus1 at ahc1 bus 0 # Single bus device
905# device scbus3 at ahc2 bus 0 # Twin bus device
906# device scbus2 at ahc2 bus 1 # Twin bus device
907# device da0 at scbus0 target 0 unit 0
908# device da1 at scbus3 target 1
909# device da2 at scbus2 target 3
910# device sa1 at scbus1 target 6
911# device cd
912
913# "units" (SCSI logical unit number) that are not specified are

1046# Options for `isa':
1047#
1048# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1049# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1050# This option breaks suspend/resume on some portables.
1051#
1052# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1053# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1054# Automatic EOI is documented not to work for for the slave with the
1055# original i8259A, but it works for some clones and some integrated
1056# versions.
1057#
1058# MAXMEM specifies the amount of RAM on the machine; if this is not
1059# specified, FreeBSD will first read the amount of memory from the CMOS
1060# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1061# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1062# then attempt to detect the installed amount of RAM. If this probe
1063# fails to detect >64MB RAM you will have to use the MAXMEM option.
1064# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
1065# be 131072 (128 * 1024).
1066#
1067# BROKEN_KEYBOARD_RESET disables the use of the keyboard controller to
