172# CPU_BLUELIGHTNING_3X enables triple-clock mode on IBM Blue Lightning
173# CPU if CPU supports it. The default is double-clock mode on

872# SCSI DEVICE CONFIGURATION
873
874# The SCSI subsystem consists of the `base' SCSI code, a number of
875# high-level SCSI device `type' drivers, and the low-level host-adapter
876# device drivers. The host adapters are listed in the ISA and PCI
877# device configuration sections below.
878#
879# Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
880# that a given bus, target, and LUN always come on line as the same
881# device unit. In earlier versions the unit numbers were assigned
882# in the order that the devices were probed on the SCSI bus. This
883# means that if you removed a disk drive, you may have had to rewrite
884# your /etc/fstab file, and also that you had to be careful when adding
885# a new disk as it may have been probed earlier and moved your device
886# configuration around.
887
888# This old behavior is maintained as the default behavior. The unit
889# assignment begins with the first non-wired down unit for a device
890# type. For example, if you wire a disk as "da3" then the first
891# non-wired disk will be assigned da4.
892
893# The syntax for wiring down devices is:
894
895# device scbus0 at ahc0 # Single bus device
896# device scbus1 at ahc1 bus 0 # Single bus device
897# device scbus3 at ahc2 bus 0 # Twin bus device
898# device scbus2 at ahc2 bus 1 # Twin bus device
899# device da0 at scbus0 target 0 unit 0
900# device da1 at scbus3 target 1
901# device da2 at scbus2 target 3
902# device sa1 at scbus1 target 6

1039#
1040# AUTO_EOI_1 enables the `automatic EOI' feature for the master 8259A
1041# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1042# This option breaks suspend/resume on some portables.
1043#
1044# AUTO_EOI_2 enables the `automatic EOI' feature for the slave 8259A
1045# interrupt controller. This saves about 0.7-1.25 usec for each interrupt.
1046# Automatic EOI is documented not to work for for the slave with the
1047# original i8259A, but it works for some clones and some integrated
1048# versions.
1049#
1050# MAXMEM specifies the amount of RAM on the machine; if this is not
1051# specified, FreeBSD will first read the amount of memory from the CMOS
1052# RAM, so the amount of memory will initially be limited to 64MB or 16MB
1053# depending on the BIOS. If the BIOS reports 64MB, a memory probe will
1054# then attempt to detect the installed amount of RAM. If this probe
1055# fails to detect >64MB RAM you will have to use the MAXMEM option.
1056# The amount is in kilobytes, so for a machine with 128MB of RAM, it would
1057# be 131072 (128 * 1024).

1545# device rp2 at isa? port 0x340
