2013 sys161.conf for ASST1
# Sample sys161.conf file
#
# This file tells System/161 what devices to use.
#
# There are 32 LAMEbus slots on the System/161 motherboard. There may
# be only one bus controller card, and it must go in slot 31. Other
# than that, you can put in whatever devices you want.
#
# The syntax is simple: one slot per line; the slot number goes first,
# then the expansion card name, then any arguments. Some of the devices
# have required arguments.
#
# The devices are:
#
# mainboard The multiprocessor LAMEbus controller card. Must go in
# slot 31, and only in slot 31. Required argument
# "ramsize=NUMBER" specifies the amount of physical RAM in
# the system. This amount must be a multiple of the
# hardware page size (which is probably 4096 or 8192.) The
# maximum amount of RAM allowed is 16M; this restriction
# is meant as a sanity check and can be altered by
# recompiling System/161. The argument "cpus=NUMBER"
# selects the number of CPUs; the default is 1 and the
# maximum 32.
#
# oldmainboard The uniprocessor LAMEbus controller card, fully
# backwards compatible with OS/161 1.x. In general,
# uniprocessor kernels should nonetheless work on the
# multiprocessor mainboard; therefore this device will
# probably be removed in the future. Configuration is the
# same as the multiprocessor mainboard, except that the
# "cpus" argument is not accepted. The OS/161 1.x name
# "busctl" is an alias for "oldmainboard".
#
# trace The System/161 trace controller device. This can be used
# by software for various debugging purposes. You can have
# more than one trace card, but they all manipulate the
# same internal state. No arguments.
#
# timer Countdown timer. The timer card also contains a real-time
# clock and a small speaker for beeping. Most configurations
# will include at least one timer. No arguments.
#
# serial Serial port. This is connected to the standard input and
# standard output of the System/161 process, and serves as
# the system console. Most configurations need this. There
# is no support at present for more than one serial port.
# No arguments.
#
# screen Full-screen memory-mapped text video card. This is
# connected to the standard input and standard output of
# the System/161 process, and serves as the system console.
# There is no support at present for more than one screen.
# Likewise, at present you may not use "screen" and "serial"
# together. No arguments. NOTE: not presently implemented.
#
# random (Pseudo-)random number generator. This accesses the
# randomizer state within System/161; thus, while you can
# add multiple random cards, they all return values from the
# same pseudorandom sequence. The random seed is set by
# using either the "seed=NUMBER" argument, which sets the
# random seed to a specified value, or the "autoseed"
# argument, which sets the random seed based on the host
# system clock. If neither argument is given or no random
# device is used, the seed is set to 0. Note that the seed
# affects various randomized behavior of the system as well
# as the values provided by the random device.
#
# disk Fixed disk. The options are as follows:
# rpm=NUMBER Set spin rate of disk.
# sectors=NUMBER Set disk size. Each sector is 512 bytes.
# file=PATH Specify file to use as storage for disk.
# paranoid Set paranoid mode.
#
# The "file=PATH" argument must be supplied. The size must be
# at least 128 sectors (64k), and the RPM setting must be a
# multiple of 60.
#
# The "paranoid" argument, if given, causes fsync() to be
# called on every disk write to make sure the data written
# reaches actual stable storage. This will make things very
# slow.
#
# You can have as many disks as you want (until you run out
# of slots) but each should have a distinct file to use for
# storage. Most common setups will use two separate disks,
# one for filesystem storage and one for swapping.
#
# nic Network card. This allows communication among multiple
# simultaneously-running copies of System/161. The arguments
# are:
# hub=PATH Give the path to the hub socket.
# hwaddr=NUMBER Specify the hardware-level card address.
#
# The hub socket path should be the argument supplied to the
# hub161 program. The default is ".sockets/hub".
#
# The hardware address should be unique among the systems
# connected to the same hub. It should be an integer between
# 1 and 65534. Values 0 and 65535 are reserved for special
# purposes. This argument is required.
#
# NOTE: disable (comment out) nic devices if you aren't
# actively using them, to avoid unnecessary overhead.
#
# emufs Emulator filesystem. This provides access *within*
# System/161 to the filesystem that System/161 is running
# in. There is one optional argument, "dir=PATH". The path
# specified is used as the root of the filesystem provided
# by emufs. (Note that it is possible to access the real
# parent of this root and thus any other directory; this
# argument does not restrict access.) The default path is
# ".", meaning System/161's own current directory.
#
#
# Here is a suggested default configuration: 512k RAM, two 5M disks.
#
0 serial
#0 screen
1 emufs
2 disk rpm=7200 sectors=10240 file=DISK1.img
