+INTRODUCTION
+.PP
+.I Config
+is a tool used in building 4.4BSD system images (the UNIX kernel).
+It takes a file describing a system's tunable parameters and
+hardware support, and generates a collection
+of files which are then used to build a copy of UNIX appropriate
+to that configuration.
+.I Config
+simplifies system maintenance by isolating system dependencies
+in a single, easy to understand, file.
+.PP
+This document describes the content and 
+format of system configuration
+files and the rules which must be followed when creating 
+these files.  Example configuration files are constructed
+and discussed.
+.PP
+Later sections suggest guidelines to be used in modifying
+system source and explain some of the inner workings of the
+autoconfiguration process.  Appendix D summarizes the rules
+used in calculating the most important system data structures
+and indicates some inherent system data structure size
+limitations (and how to go about modifying them).

+.\".ds RH "Configuration File Contents
+.ne 2i
+.NH
+CONFIGURATION FILE CONTENTS
+.PP
+A system configuration must include at least the following
+pieces of information:
+.IP \(bu 3
+machine type
+.IP \(bu 3
+cpu type
+.IP \(bu 3
+system identification
+.IP \(bu 3
+timezone
+.IP \(bu 3
+maximum number of users
+.IP \(bu 3
+location of the root file system
+.IP \(bu 3
+available hardware
+.PP
+.I Config
+allows multiple system images to be generated from a single
+configuration description.  Each system image is configured
+for identical hardware, but may have different locations for the root
+file system and, possibly, other system devices.
+.NH 2
+Machine type
+.PP
+The 
+.I "machine type"
+indicates if the system is going to operate on a DEC VAX-11\(dg computer,
+.FS
+\(dg DEC, VAX, UNIBUS, MASSBUS and MicroVAX are trademarks of Digital
+Equipment Corporation.
+.FE
+or some other machine on which 4.4BSD operates.  The machine type
+is used to locate certain data files which are machine specific, and
+also to select rules used in constructing the resultant
+configuration files.
+.NH 2
+Cpu type
+.PP
+The
+.I "cpu type"
+indicates which, of possibly many, cpu's the system is to operate on.
+For example, if the system is being configured for a VAX-11, it could
+be running on a VAX 8600, VAX-11/780, VAX-11/750, VAX-11/730 or MicroVAX II.
+(Other VAX cpu types, including the 8650, 785 and 725, are configured using
+the cpu designation for compatible machines introduced earlier.)
+Specifying
+more than one cpu type implies that the system should be configured to run
+on any of the cpu's specified.  For some types of machines this is not
+possible and 
+.I config
+will print a diagnostic indicating such.
+.NH 2
+System identification
+.PP
+The
+.I "system identification"
+is a moniker attached to the system, and often the machine on which the
+system is to run.  For example, at Berkeley we have machines named Ernie
+(Co-VAX), Kim (No-VAX), and so on.  The system identifier selected is used to
+create a global C ``#define'' which may be used to isolate system dependent
+pieces of code in the kernel.  For example, Ernie's Varian driver used
+to be special cased because its interrupt vectors were wired together.  The
+code in the driver which understood how to handle this non-standard hardware
+configuration was conditionally compiled in only if the system
+was for Ernie.  
+.PP
+The system identifier ``GENERIC'' is given to a system which
+will run on any cpu of a particular machine type; it should not
+otherwise be used for a system identifier.
+.NH 2
+Timezone
+.PP
+The timezone in which the system is to run is used to define the
+information returned by the \fIgettimeofday\fP\|(2)
+system call.  This value is specified as the number of hours east
+or west of GMT.  Negative numbers indicate a value east of GMT.
+The timezone specification may also indicate the
+type of daylight savings time rules to be applied.
+.NH 2
+Maximum number of users
+.PP
+The system allocates many system data structures at boot time
+based on the maximum number of users the system will support.
+This number is normally between 8 and 40, depending
+on the hardware and expected job mix.  The rules
+used to calculate system data structures are discussed in
+Appendix D.
+.NH 2
+Root file system location
+.PP
+When the system boots it must know the location of
+the root of the file system
+tree.  This location and the part(s) of the disk(s) to be used
+for paging and swapping must be specified in order to create
+a complete configuration description.  
+.I Config
+uses many rules to calculate default locations for these items;
+these are described in Appendix B.
+.PP
+When a generic system is configured, the root file system is left
+undefined until the system is booted.  In this case, the root file
+system need not be specified, only that the system is a generic system.
+.NH 2
+Hardware devices
+.PP
+When the system boots it goes through an
+.I autoconfiguration
+phase.  During this period, the system searches for all
+those hardware devices
+which the system builder has indicated might be present.  This probing
+sequence requires certain pieces of information such as register
+addresses, bus interconnects, etc.  A system's hardware may be configured
+in a very flexible manner or be specified without any flexibility
+whatsoever.  Most people do not configure hardware devices into the
+system unless they are currently present on the machine, expect
+them to be present in the near future, or are simply guarding
+against a hardware
+failure somewhere else at the site (it is often wise to configure in
+extra disks in case an emergency requires moving one off a machine which
+has hardware problems).
+.PP
+The specification of hardware devices usually occupies the majority of
+the configuration file.  As such, a large portion of this document will
+be spent understanding it.  Section 6.3 contains a description of
+the autoconfiguration process, as it applies to those planning to
+write, or modify existing, device drivers.
+.NH 2
+Pseudo devices
+.PP
+Several system facilities are configured in a manner like that used
+for hardware devices although they are not associated with specific hardware.
+These system options are configured as
+.IR pseudo-devices .
+Some pseudo devices allow an optional parameter that sets the limit
+on the number of instances of the device that are active simultaneously.
+.NH 2
+System options
+.PP
+Other than the mandatory pieces of information described above, it
+is also possible to include various optional system facilities
+or to modify system behavior and/or limits.
+For example, 4.4BSD can be configured to support binary compatibility for
+programs built under 4.3BSD.  Also, optional support is provided
+for disk quotas and tracing the performance of the virtual memory
+subsystem.  Any optional facilities to be configured into
+the system are specified in the configuration file.  The resultant
+files generated by
+.I config
+will automatically include the necessary pieces of the system.

+.ne 2i
+.NH
+SYSTEM BUILDING PROCESS
+.PP
+In this section we consider the steps necessary to build a bootable system
+image.  We assume the system source is located in the ``/sys'' directory
+and that, initially, the system is being configured from source code.
+.PP
+Under normal circumstances there are 5 steps in building a system.
+.IP 1) 3
+Create a configuration file for the system.
+.IP 2) 3
+Make a directory for the system to be constructed in.
+.IP 3) 3
+Run
+.I config
+on the configuration file to generate the files required
+to compile and load the system image.
+.IP 4)
+Construct the source code interdependency rules for the
+configured system with
+.I make depend
+using
+.IR make (1).
+.IP 5)
+Compile and load the system with 
+.IR make .
+.PP
+Steps 1 and 2 are usually done only once.  When a system configuration
+changes it usually suffices to just run
+.I config
+on the modified configuration file, rebuild the source code dependencies,
+and remake the system.  Sometimes,
+however, configuration dependencies may not be noticed in which case
+it is necessary to clean out the relocatable object files saved
+in the system's directory; this will be discussed later.
+.NH 2
+Creating a configuration file
+.PP
+Configuration files normally reside in the directory ``/sys/conf''.
+A configuration file is most easily constructed by copying an
+existing configuration file and modifying it.  The 4.4BSD distribution
+contains a number of configuration files for machines at Berkeley;
+one may be suitable or, in worst case, a copy
+of the generic configuration file may be edited.
+.PP
+The configuration file must have the same name as the directory in
+which the configured system is to be built.  
+Further,
+.I config
+assumes this directory is located in the parent directory of
+the directory in which it
+is run.  For example, the generic
+system has a configuration file ``/sys/conf/GENERIC'' and an accompanying
+directory named ``/sys/GENERIC''.
+Although it is not required that the system sources and configuration
+files reside in ``/sys,'' the configuration and compilation procedure
+depends on the relative locations of directories within that hierarchy,
+as most of the system code and the files created by
+.I config
+use pathnames of the form ``../''.
+If the system files are not located in ``/sys,''
+it is desirable to make a symbolic link there for use in installation
+of other parts of the system that share files with the kernel.
+.PP
+When building the configuration file, be sure to include the items
+described in section 2.  In particular, the machine type,
+cpu type, timezone, system identifier, maximum users, and root device
+must be specified.  The specification of the hardware present may take
+a bit of work; particularly if your hardware is configured at non-standard
+places (e.g. device registers located at funny places or devices not
+supported by the system).  Section 4 of this document
+gives a detailed description of the configuration file syntax,
+section 5 explains some sample configuration files, and
+section 6 discusses how to add new devices to
+the system.  If the devices to be configured are not already
+described in one of the existing configuration files you should check
+the manual pages in section 4 of the UNIX Programmers Manual.  For each
+supported device, the manual page synopsis entry gives a
+sample configuration line.
+.PP
+Once the configuration file is complete, run it through
+.I config
+and look for any errors.  Never try and use a system which
+.I config
+has complained about; the results are unpredictable.
+For the most part,
+.IR config 's
+error diagnostics are self explanatory.  It may be the case that
+the line numbers given with the error messages are off by one.
+.PP
+A successful run of
+.I config
+on your configuration file will generate a number of files in
+the configuration directory.  These files are:
+.IP \(bu 3
+A file to be used by \fImake\fP\|(1)
+in compiling and loading the system,
+.IR Makefile .
+.IP \(bu 3
+One file for each possible system image for this machine,
+.IR swapxxx.c ,
+where
+.I xxx
+is the name of the system image,
+which describes where swapping, the root file system, and other
+miscellaneous system devices are located.
+.IP \(bu 3
+A collection of header files, one per possible device the
+system supports, which define the hardware configured.
+.IP \(bu 3
+A file containing the I/O configuration tables used by the system
+during its 
+.I autoconfiguration
+phase,
+.IR ioconf.c .
+.IP \(bu 3
+An assembly language file of interrupt vectors which
+connect interrupts from the machine's external buses to the main
+system path for handling interrupts,
+and a file that contains counters and names for the interrupt vectors.
+.PP
+Unless you have reason to doubt 
+.IR config ,
+or are curious how the system's autoconfiguration scheme
+works, you should never have to look at any of these files.
+.NH 2
+Constructing source code dependencies
+.PP
+When 
+.I config
+is done generating the files needed to compile and link your system it
+will terminate with a message of the form ``Don't forget to run make depend''.
+This is a reminder that you should change over to the configuration
+directory for the system just configured and type ``make depend''
+to build the rules used by 
+.I make
+to recognize interdependencies in the system source code.
+This will insure that any changes to a piece of the system
+source code will result in the proper modules being recompiled
+the next time
+.I make
+is run.
+.PP
+This step is particularly important if your site makes changes
+to the system include files.  The rules generated specify which source code
+files are dependent on which include files.  Without these rules,
+.I make
+will not recognize when it must rebuild modules
+due to the modification of a system header file.
+The dependency rules are generated by a pass of the C preprocessor
+and reflect the global system options.
+This step must be repeated when the configuration file is changed
+and
+.I config
+is used to regenerate the system makefile.
+.NH 2
+Building the system
+.PP
+The makefile constructed by
+.I config
+should allow a new system to be rebuilt by simply typing ``make image-name''.
+For example, if you have named your bootable system image ``vmunix'',
+then ``make vmunix''
+will generate a bootable image named ``vmunix''.  Alternate system image names
+are used when the root file system location and/or swapping configuration
+is done in more than one way.  The makefile which
+.I config
+creates has entry points for each system image defined in
+the configuration file.
+Thus, if you have configured ``vmunix'' to be a system with the root file
+system on an ``hp'' device and ``hkvmunix'' to be a system with the root
+file system on an ``hk'' device, then ``make vmunix hkvmunix'' will generate
+binary images for each.
+As the system will generally use the disk from which it is loaded
+as the root filesystem, separate system images are only required
+to support different swap configurations.
+.PP
+Note that the name of a bootable image is different from the system
+identifier.  All bootable images are configured for the same system;
+only the information about the root file system and paging devices differ.
+(This is described in more detail in section 4.)
+.PP
+The last step in the system building process is to rearrange certain commonly
+used symbols in the symbol table of the system image;  the makefile
+generated by 
+.I config
+does this automatically for you.
+This is advantageous for programs such as
+\fInetstat\fP\|(1) and \fIvmstat\fP\|(1),
+which run much faster when the symbols they need are located at
+the front of the symbol table.  
+Remember also that many programs expect
+the currently executing system to be named ``/vmunix''.  If you install
+a new system and name it something other than ``/vmunix'', many programs
+are likely to give strange results.
+.NH 2
+Sharing object modules
+.PP
+If you have many systems which are all built on a single machine
+there are at least two approaches to saving time in building system
+images.  The best way is to have a single system image which is run on
+all machines.  This is attractive since it minimizes disk space used
+and time required to rebuild systems after making changes.  However,
+it is often the case that one or more systems will require a separately
+configured system image.  This may be due to limited memory (building
+a system with many unused device drivers can be expensive), or to
+configuration requirements (one machine may be a development machine
+where disk quotas are not needed, while another is a production machine
+where they are), etc.  In these cases it is possible
+for common systems to share relocatable object modules which are not
+configuration dependent; most of the modules in the directory ``/sys/sys''
+are of this sort.
+.PP
+To share object modules, a generic system should be built.  Then, for
+each system configure the system as before, but before recompiling and
+linking the system, type ``make links'' in the system compilation directory.
+This will cause the system
+to be searched for source modules which are safe to share between systems
+and generate symbolic links in the current directory to the appropriate
+object modules in the directory ``../GENERIC''.  A shell script,
+``makelinks'' is generated with this request and may be checked for
+correctness.  The file ``/sys/conf/defines'' contains a list of symbols
+which we believe are safe to ignore when checking the source code
+for modules which may be shared.  Note that this list includes the definitions
+used to conditionally compile in the virtual memory tracing facilities, and
+the trace point support used only rarely (even at Berkeley). 
+It may be necessary
+to modify this file to reflect local needs.  Note further that
+interdependencies which are not directly visible
+in the source code are not caught.  This means that if you place
+per-system dependencies in an include file, they will not be recognized
+and the shared code may be selected in an unexpected fashion.
+.NH 2
+Building profiled systems
+.PP
+It is simple to configure a system which will automatically
+collect profiling information as it operates.  The profiling data
+may be collected with \fIkgmon\fP\|(8) and processed with
+\fIgprof\fP\|(1)
+to obtain information regarding the system's operation.  Profiled
+systems maintain histograms of the program counter as well as the
+number of invocations of each routine.  The \fIgprof\fP
+command will also generate a dynamic call graph of the executing
+system and propagate time spent in each routine along the arcs
+of the call graph (consult the \fIgprof\fP documentation for elaboration).
+The program counter sampling can be driven by the system clock, or
+if you have an alternate real time clock, this can be used.  The 
+latter is highly recommended, as use of the system clock will result
+in statistical anomalies, and time spent in the clock routine will
+not be accurately attributed.
+.PP
+To configure a profiled system, the
+.B \-p
+option should be supplied to \fIconfig\fP.
+A profiled system is about 5-10% larger in its text space due to
+the calls to count the subroutine invocations.  When the system
+executes, the profiling data is stored in a buffer which is 1.2
+times the size of the text space.  The overhead for running a
+profiled system varies; under normal load we see anywhere from 5-25%
+of the system time spent in the profiling code.
+.PP
+Note that systems configured for profiling should not be shared as
+described above unless all the other shared systems are also to be
+profiled.

+.NH
+CONFIGURATION FILE SYNTAX
+.PP
+In this section we consider the specific rules used in writing
+a configuration file.  A complete grammar for the input language
+can be found in Appendix A and may be of use if you should have
+problems with syntax errors.
+.PP
+A configuration file is broken up into three logical pieces:
+.IP \(bu 3
+configuration parameters global to all system images 
+specified in the configuration file,
+.IP \(bu 3
+parameters specific to each
+system image to be generated, and
+.IP \(bu 3
+device specifications.
+.NH 2
+Global configuration parameters
+.PP
+The global configuration parameters are the type of machine,
+cpu types, options, timezone, system identifier, and maximum users.
+Each is specified with a separate line in the configuration file.
+.IP "\fBmachine\fP \fItype\fP"
+.br
+The system is to run on the machine type specified.  No more than
+one machine type can appear in the configuration file.  Legal values
+are
+.B vax
+and
+\fBsun\fP.
+.IP "\fBcpu\fP ``\fItype\fP''"
+.br
+This system is to run on the cpu type specified.
+More than one cpu type specification
+can appear in a configuration file.
+Legal types for a
+.B vax
+machine are
+\fBVAX8600\fP, \fBVAX780\fP, \fBVAX750\fP,
+\fBVAX730\fP
+and
+\fBVAX630\fP (MicroVAX II).
+The 8650 is listed as an 8600, the 785 as a 780, and a 725 as a 730.
+.IP "\fBoptions\fP \fIoptionlist\fP"
+.br
+Compile the listed optional code into the system. 
+Options in this list are separated by commas.
+Possible options are listed at the top of the generic makefile.
+A line of the form ``options FUNNY,HAHA'' generates global ``#define''s
+\-DFUNNY \-DHAHA in the resultant makefile.
+An option may be given a value by following its name with ``\fB=\fP'',
+then the value enclosed in (double) quotes.
+The following are major options are currently in use:
+COMPAT (include code for compatibility with 4.1BSD binaries),
+INET (Internet communication protocols),
+NS (Xerox NS communication protocols),
+and
+QUOTA (enable disk quotas).
+Other kernel options controlling system sizes and limits
+are listed in Appendix D;
+options for the network are found in Appendix E.
+There are additional options which are associated with certain
+peripheral devices; those are listed in the Synopsis section
+of the manual page for the device.
+.IP "\fBmakeoptions\fP \fIoptionlist\fP"
+.br
+Options that are used within the system makefile
+and evaluated by
+.I make
+are listed as
+.IR makeoptions .
+Options are listed with their values with the form
+``makeoptions name=value,name2=value2.''
+The values must be enclosed in double quotes if they include numerals
+or begin with a dash.
+.IP "\fBtimezone\fP \fInumber\fP [ \fBdst\fP [ \fInumber\fP ] ]"
+.br
+Specifies the timezone used by the system.  This is measured in the
+number of hours your timezone is west of GMT.  
+EST is 5 hours west of GMT, PST is 8.  Negative numbers
+indicate hours east of GMT. If you specify
+\fBdst\fP, the system will operate under daylight savings time.
+An optional integer or floating point number may be included
+to specify a particular daylight saving time correction algorithm;
+the default value is 1, indicating the United States.
+Other values are: 2 (Australian style), 3 (Western European),
+4 (Middle European), and 5 (Eastern European).  See
+\fIgettimeofday\fP\|(2) and \fIctime\fP\|(3) for more information.
+.IP "\fBident\fP \fIname\fP"
+.br
+This system is to be known as
+.IR name .
+This is usually a cute name like ERNIE (short for Ernie Co-Vax) or
+VAXWELL (for Vaxwell Smart).
+This value is defined for use in conditional compilation,
+and is also used to locate an optional list of source files specific
+to this system.
+.IP "\fBmaxusers\fP \fInumber\fP"
+.br
+The maximum expected number of simultaneously active user on this system is
+.IR number .
+This number is used to size several system data structures.
+.NH 2
+System image parameters
+.PP
+Multiple bootable images may be specified in a single configuration
+file.  The systems will have the same global configuration parameters
+and devices, but the location of the root file system and other
+system specific devices may be different.  A system image is specified
+with a ``config'' line:
+.IP
+\fBconfig\fP\ \fIsysname\fP\ \fIconfig-clauses\fP
+.LP
+The
+.I sysname
+field is the name given to the loaded system image; almost everyone
+names their standard system image ``vmunix''.  The configuration clauses
+are one or more specifications indicating where the root file system
+is located and the number and location of paging devices.
+The device used by the system to process argument lists during
+.IR execve (2)
+calls may also be specified, though in practice this is almost
+always selected by
+.I config
+using one of its rules for selecting default locations for
+system devices.
+.PP
+A configuration clause is one of the following
+.IP
+.nf
+\fBroot\fP [ \fBon\fP ] \fIroot-device\fP
+\fBswap\fP [ \fBon\fP ] \fIswap-device\fP [ \fBand\fP \fIswap-device\fP ] ...
+\fBdumps\fP [ \fBon\fP ] \fIdump-device\fP
+\fBargs\fP [ \fBon\fP ] \fIarg-device\fP
+.LP
+(the ``on'' is optional.)  Multiple configuration clauses
+are separated by white space; 
+.I config
+allows specifications to be continued across multiple lines
+by beginning the continuation line with a tab character.
+The ``root'' clause specifies where the root file system
+is located, the ``swap'' clause indicates swapping and paging
+area(s), the ``dumps'' clause can be used to force system dumps
+to be taken on a particular device, and the ``args'' clause
+can be used to specify that argument list processing for
+.I execve
+should be done on a particular device.
+.PP
+The device names supplied in the clauses may be fully specified
+as a device, unit, and file system partition; or underspecified
+in which case
+.I config
+will use builtin rules to select default unit numbers and file
+system partitions.  The defaulting rules are a bit complicated
+as they are dependent on the overall system configuration.
+For example, the swap area need not be specified at all if 
+the root device is specified; in this case the swap area is
+placed in the ``b'' partition of the same disk where the root
+file system is located.  Appendix B contains a complete list
+of the defaulting rules used in selecting system configuration
+devices.
+.PP
+The device names are translated to the
+appropriate major and minor device
+numbers on a per-machine basis.  A file,
+``/sys/conf/devices.machine'' (where ``machine''
+is the machine type specified in the configuration file),
+is used to map a device name to its major block device number.
+The minor device number is calculated using the standard 
+disk partitioning rules: on unit 0, partition ``a'' is minor device
+0, partition ``b'' is minor device 1, and so on; for units
+other than 0, add 8 times the unit number to get the minor
+device.
+.PP
+If the default mapping of device name to major/minor device
+number is incorrect for your configuration, it can be replaced
+by an explicit specification of the major/minor device.
+This is done by substituting
+.IP
+\fBmajor\fP \fIx\fP \fBminor\fP \fIy\fP
+.LP
+where the device name would normally be found.  For example,
+.IP
+.nf
+\fBconfig\fP vmunix \fBroot\fP \fBon\fP \fBmajor\fP 99 \fBminor\fP 1
+.fi
+.PP
+Normally, the areas configured for swap space are sized by the system
+at boot time.  If a non-standard size is to be used for one
+or more swap areas (less than the full partition),
+this can also be specified.  To do this, the
+device name specified for a swap area should have a ``size''
+specification appended.  For example,
+.IP
+.nf
+\fBconfig\fP vmunix \fBroot\fP \fBon\fP hp0 \fBswap\fP \fBon\fP hp0b \fBsize\fP 1200
+.fi
+.LP
+would force swapping to be done in partition ``b'' of ``hp0'' and
+the swap partition size would be set to 1200 sectors.  A swap area
+sized larger than the associated disk partition is trimmed to the
+partition size.
+.PP
+To create a generic configuration, only the clause ``swap generic''
+should be specified; any extra clauses will cause an error.
+.NH 2
+Device specifications
+.PP
+Each device attached to a machine must be specified
+to
+.I config
+so that the system generated will know to probe for it during
+the autoconfiguration process carried out at boot time.  Hardware
+specified in the configuration need not actually be present on
+the machine where the generated system is to be run.  Only the
+hardware actually found at boot time will be used by the system.
+.PP
+The specification of hardware devices in the configuration file
+parallels the interconnection hierarchy of the machine to be
+configured.  On the VAX, this means that a configuration file must
+indicate what MASSBUS and UNIBUS adapters are present, and to
+which \fInexi\fP they might be connected.* 
+.FS
+* While VAX-11/750's and VAX-11/730 do not actually have 
+nexi, the system treats them as having 
+.I "simulated nexi"
+to simplify device configuration.
+.FE
+Similarly, devices
+and controllers must be indicated as possibly being connected
+to one or more adapters.  A device description may provide a
+complete definition of the possible configuration parameters
+or it may leave certain parameters undefined and make the system
+probe for all the possible values.  The latter allows a single
+device configuration list to match many possible physical
+configurations.  For example, a disk may be indicated as present
+at UNIBUS adapter 0, or at any UNIBUS adapter which the system
+locates at boot time.  The latter scheme, termed 
+.IR wildcarding ,
+allows more flexibility in the physical configuration of a system;
+if a disk must be moved around for some reason, the system will
+still locate it at the alternate location.
+.PP
+A device specification takes one of the following forms:
+.IP
+.nf
+\fBmaster\fP \fIdevice-name\fP \fIdevice-info\fP
+\fBcontroller\fP \fIdevice-name\fP \fIdevice-info\fP [ \fIinterrupt-spec\fP ]
+\fBdevice\fP \fIdevice-name\fP \fIdevice-info\fP \fIinterrupt-spec\fP
+\fBdisk\fP \fIdevice-name\fP \fIdevice-info\fP
+\fBtape\fP \fIdevice-name\fP \fIdevice-info\fP
+.fi
+.LP
+A ``master'' is a MASSBUS tape controller; a ``controller'' is a
+disk controller, a UNIBUS tape controller, a MASSBUS adapter, or
+a UNIBUS adapter.  A ``device'' is an autonomous device which
+connects directly to a UNIBUS adapter (as opposed to something
+like a disk which connects through a disk controller).  ``Disk''
+and ``tape'' identify disk drives and tape drives connected to
+a ``controller'' or ``master.''
+.PP
+The
+.I device-name
+is one of the standard device names, as
+indicated in section 4 of the UNIX Programmers Manual,
+concatenated with the
+.I logical
+unit number to be assigned the device (the 
+.I logical
+unit number may be different than the
+.I physical
+unit number indicated on the front of something
+like a disk; the
+.I logical
+unit number is used to refer to the UNIX device, not
+the physical unit number).  For example, ``hp0'' is logical
+unit 0 of a MASSBUS storage device, even though it might
+be physical unit 3 on MASSBUS adapter 1.
+.PP
+The
+.I device-info
+clause specifies how the hardware is
+connected in the interconnection hierarchy.  On the VAX,
+UNIBUS and MASSBUS adapters are connected to the internal
+system bus through
+a \fInexus\fP.
+Thus, one of the following
+specifications would be used:
+.IP
+.ta 1.5i 2.5i 4.0i
+.nf
+\fBcontroller\fP	mba0	\fBat\fP \fBnexus\fP \fIx\fP
+\fBcontroller\fP	uba0	\fBat\fP \fBnexus\fP \fIx\fP
+.fi
+.LP
+To tie a controller to a specific nexus, ``x'' would be supplied
+as the number of that nexus; otherwise ``x'' may be specified as
+``?'', in which
+case the system will probe all nexi present looking
+for the specified controller.
+.PP
+The remaining interconnections on the VAX are:
+.IP \(bu 3
+a controller
+may be connected to another controller (e.g. a disk controller attached
+to a UNIBUS adapter),
+.IP \(bu 3
+a master is always attached to a controller (a MASSBUS adapter),
+.IP \(bu 3
+a tape is always attached to a master (for MASSBUS
+tape drives),
+.IP \(bu 3
+a disk is always attached to a controller, and
+.IP \(bu 3
+devices
+are always attached to controllers (e.g. UNIBUS controllers attached
+to UNIBUS adapters).
+.LP
+The following lines give an example of each of these interconnections:
+.IP
+.ta 1.5i 2.5i 4.0i
+.nf
+\fBcontroller\fP	hk0	\fBat\fP uba0 ...
+\fBmaster\fP	ht0	\fBat\fP mba0 ...
+\fBdisk\fP	hp0	\fBat\fP mba0 ...
+\fBtape\fP	tu0	\fBat\fP ht0 ...
+\fBdisk\fP	rk1	\fBat\fP hk0 ...
+\fBdevice\fP	dz0	\fBat\fP uba0 ...
+.fi
+.LP
+Any piece of hardware which may be connected to a specific
+controller may also be wildcarded across multiple controllers.
+.PP
+The final piece of information needed by the system to configure
+devices is some indication of where or how a device will interrupt.
+For tapes and disks, simply specifying the \fIslave\fP or \fIdrive\fP
+number is sufficient to locate the control status register for the
+device.
+\fIDrive\fP numbers may be wildcarded
+on MASSBUS devices, but not on disks on a UNIBUS controller.
+For controllers, the control status register must be
+given explicitly, as well the number of interrupt vectors used and
+the names of the routines to which they should be bound. 
+Thus the example lines given above might be completed as:
+.IP
+.ta 1.5i 2.5i 4.0i
+.nf
+\fBcontroller\fP	hk0	\fBat\fP uba0 \fBcsr\fP 0177440	\fBvector\fP rkintr
+\fBmaster\fP	ht0	\fBat\fP mba0 \fBdrive\fP 0
+\fBdisk\fP	hp0	\fBat\fP mba0 \fBdrive\fP ?
+\fBtape\fP	tu0	\fBat\fP ht0 \fBslave\fP 0
+\fBdisk\fP	rk1	\fBat\fP hk0 \fBdrive\fP 1
+\fBdevice\fP	dz0	\fBat\fP uba0 \fBcsr\fP 0160100	\fBvector\fP dzrint dzxint
+.fi
+.PP
+Certain device drivers require extra information passed to them
+at boot time to tailor their operation to the actual hardware present.
+The line printer driver, for example, needs to know how many columns
+are present on each non-standard line printer (i.e. a line printer
+with other than 80 columns).  The drivers for the terminal multiplexors
+need to know which lines are attached to modem lines so that no one will
+be allowed to use them unless a connection is present.  For this reason,
+one last parameter may be specified to a
+.IR device ,
+a 
+.I flags
+field.  It has the syntax
+.IP
+\fBflags\fP \fInumber\fP
+.LP
+and is usually placed after the
+.I csr
+specification.  The
+.I number
+is passed directly to the associated driver.  The manual pages
+in section 4 should be consulted to determine how each driver
+uses this value (if at all).
+Communications interface drivers commonly use the flags
+to indicate whether modem control signals are in use.
+.PP
+The exact syntax for each specific device is given in the Synopsis
+section of its manual page in section 4 of the manual.
+.NH 2
+Pseudo-devices
+.PP
+A number of drivers and software subsystems
+are treated like device drivers without any associated hardware.
+To include any of these pieces, a ``pseudo-device'' specification
+must be used.  A specification for a pseudo device takes the form
+.IP
+.DT
+.nf
+\fBpseudo-device\fP	\fIdevice-name\fP [ \fIhowmany\fP ]
+.fi
+.PP
+Examples of pseudo devices are
+\fBpty\fP, the pseudo terminal driver (where the optional
+.I howmany
+value indicates the number of pseudo terminals to configure, 32 default),
+and \fBloop\fP, the software loopback network pseudo-interface.
+Other pseudo devices for the network include
+\fBimp\fP (required when a CSS or ACC imp is configured)
+and \fBether\fP (used by the Address Resolution Protocol
+on 10 Mb/sec Ethernets).
+More information on configuring each of these can also be found
+in section 4 of the manual.

+SAMPLE CONFIGURATION FILES

+In this section we will consider how to configure a
+sample VAX-11/780 system on which the hardware can be

+We then study the rules needed to configure a VAX-11/750
+to run in a networking environment.
+.NH 2
+VAX-11/780 System
+.PP
+Our VAX-11/780 is configured with hardware

+Table 1.  VAX-11/780 Hardware support.
+.LP
+We will call this machine ANSEL and construct a configuration
+file one step at a time.
+.PP
+The first step is to fill in the global configuration parameters.
+The machine is a VAX, so the
+.I "machine type"
+is ``vax''.  We will assume this system will
+run only on this one processor, so the 
+.I "cpu type"
+is ``VAX780''.  The options are empty since this is going to
+be a ``vanilla'' VAX.  The system identifier, as mentioned before,
+is ``ANSEL,'' and the maximum number of users we plan to support is
+about 40.  Thus the beginning of the configuration file looks like
+this:
+.DS
+.ta 1.5i 2.5i 4.0i
+#
+# ANSEL VAX (a picture perfect machine)
+#
+machine	vax
+cpu	VAX780
+timezone	8 dst
+ident	ANSEL
+maxusers	40
+.DE
+.PP
+To this we must then add the specifications for three
+system images.  The first will be our standard system with the
+root on ``hp0'' and swapping on the same drive as the root.
+The second will have the root file system in the same location,
+but swap space interleaved among drives on each controller.
+Finally, the third will be a generic system,
+to allow us to boot off any of the four disk drives.
+.DS
+.ta 1.5i 2.5i
+config	vmunix	root on hp0
+config	hpvmunix	root on hp0 swap on hp0 and hp2
+config	genvmunix	swap generic
+.DE
+.PP
+Finally, the hardware must be specified.  Let us first just try
+transcribing the information from Table 1.
+.DS
+.ta 1.5i 2.5i 4.0i
+controller	mba0	at nexus ?
+disk	hp0	at mba0 disk 0
+disk	hp1	at mba0 disk 1

+device	dh2	at uba0 csr 0160060	vector dhrint dhxint
+.DE
+.LP
+(Oh, I forgot to mention one panel of the terminal multiplexor
+has modem control, thus the ``dm0'' device.)
+.PP
+This will suffice, but leaves us with little flexibility.  Suppose
+our first disk controller were to break.  We would like to recable the
+drives normally on the second controller so that all our disks could
+still be used without reconfiguring the system.  To do this we wildcard
+the MASSBUS adapter connections and also the slave numbers.  Further,
+we wildcard the UNIBUS adapter connections in case we decide some time
+in the future to purchase another adapter to offload the single UNIBUS
+we currently have.  The revised device specifications would then be:
+.DS
+.ta 1.5i 2.5i 4.0i

+VAX-11/750 with network support
+.PP
+Our VAX-11/750 system will be located on two 10Mb/s Ethernet
+local area networks and also the DARPA Internet.  The system
+will have a MASSBUS drive for the root file system and two
+UNIBUS drives.  Paging is interleaved among all three drives.
+We have sold our standard DEC terminal multiplexors since this
+machine will be accessed solely through the network.  This
+machine is not intended to have a large user community, it
+does not have a great deal of memory.  First the global parameters:
+.DS
+.ta 1.5i 2.5i 4.0i
+#
+# UCBVAX (Gateway to the world)
+#
+machine	vax
+cpu	"VAX780"
+cpu	"VAX750"
+ident	UCBVAX
+timezone	8 dst
+maxusers	32
+options	INET
+options	NS
+.DE
+.PP
+The multiple cpu types allow us to replace UCBVAX with a
+more powerful cpu without reconfiguring the system.  The
+value of 32 given for the maximum number of users is done to
+force the system data structures to be over-allocated.  That
+is desirable on this machine because, while it is not expected
+to support many users, it is expected to perform a great deal
+of work.
+The ``INET'' indicates that we plan to use the
+DARPA standard Internet protocols on this machine,
+and ``NS'' also includes support for Xerox NS protocols.
+Note that unlike 4.2BSD configuration files,
+the network protocol options do not require corresponding pseudo devices.
+.PP
+The system images and disks are configured next.

+.DE
+.PP
+UCBVAX requires heavy interleaving of its paging area to keep up
+with all the mail traffic it handles.  The limiting factor on this
+system's performance is usually the number of disk arms, as opposed
+to memory or cpu cycles.  The extra UNIBUS controller, ``sc0'',
+is in case the MASSBUS controller breaks and a spare controller
+must be installed (most of our old UNIBUS controllers have been
+replaced with the newer MASSBUS controllers, so we have a number
+of these around as spares).
+.PP
+Finally, we add in the network devices.
+Pseudo terminals are needed to allow users to
+log in across the network (remember the only hardwired terminal
+is the console).
+The software loopback device is used for on-machine communications.
+The connection to the Internet is through
+an IMP, this requires yet another
+.I pseudo-device
+(in addition to the actual hardware device used by the
+IMP software).  And, finally, there are the two Ethernet devices.
+These use a special protocol, the Address Resolution Protocol (ARP),
+to map between Internet and Ethernet addresses.  Thus, yet another
+.I pseudo-device
+is needed.  The additional device specifications are show below.

+Miscellaneous comments
+.PP
+It should be noted in these examples that neither system was
+configured to use disk quotas or the 4.1BSD compatibility mode.
+To use these optional facilities, and others, we would probably
+clean out our current configuration, reconfigure the system, then
+recompile and relink the system image(s).  This could, of course,
+be avoided by figuring out which relocatable object files are 
+affected by the reconfiguration, then reconfiguring and recompiling
+only those files affected by the configuration change.  This technique
+should be used carefully.

+ADDING NEW SYSTEM SOFTWARE
+.PP
+This section is not for the novice, it describes
+some of the inner workings of the configuration process as
+well as the pertinent parts of the system autoconfiguration process.
+It is intended to give
+those people who intend to install new device drivers and/or
+other system facilities sufficient information to do so in the
+manner which will allow others to easily share the changes.
+.PP
+This section is broken into four parts:
+.IP \(bu 3
+general guidelines to be followed in modifying system code,
+.IP \(bu 3
+how to add non-standard system facilities to 4.4BSD,
+.IP \(bu 3
+how to add a device driver to 4.4BSD, and
+.NH 2
+Modifying system code
+.PP
+If you wish to make site-specific modifications to the system
+it is best to bracket them with
+.DS
+#ifdef SITENAME
+\&...
+#endif
+.DE
+to allow your source to be easily distributed to others, and
+also to simplify \fIdiff\fP\|(1) listings.  If you choose not
+to use a source code control system (e.g. SCCS, RCS), and
+perhaps even if you do, it is
+recommended that you save the old code with something
+of the form:
+.DS
+#ifndef SITENAME
+\&...
+#endif
+.DE
+We try to isolate our site-dependent code in individual files
+which may be configured with pseudo-device specifications.
+.PP
+Indicate machine-specific code with ``#ifdef vax'' (or other machine,
+as appropriate).
+4.4BSD underwent extensive work to make it extremely portable to
+machines with similar architectures\- you may someday find
+yourself trying to use a single copy of the source code on
+multiple machines.
+.NH 2
+Adding non-standard system facilities
+.PP
+This section considers the work needed to augment 
+.IR config 's
+data base files for non-standard system facilities.
+.I Config
+uses a set of files that list the source modules that may be required
+when building a system.
+The data bases are taken from the directory in which
+.I config
+is run, normally /sys/conf.
+Three such files may be used:
+.IR files ,
+.IR files .machine,
+and
+.IR files .ident.
+The first is common to all systems,
+the second contains files unique to a single machine type,
+and the third is an optional list of modules for use on a specific machine.
+This last file may override specifications in the first two.
+The format of the 
+.I files
+file has grown somewhat complex over time.  Entries are normally of
+the form
+.IP
+.nf
+.DT
+\fIdir/source.c\fP	\fItype\fP	 \fIoption-list\fP \fImodifiers\fP
+.LP
+for example,
+.IP
+.nf
+.DT
+\fIvaxuba/foo.c\fP	\fBoptional\fP	foo	\fBdevice-driver\fP
+.LP
+The
+.I type
+is one of
+.B standard
+or
+.BR optional .
+Files marked as standard are included in all system configurations.
+Optional file specifications include a list of one or more system
+options that together require the inclusion of this module.
+The options in the list may be either names of devices that may
+be in the configuration file,
+or the names of system options that may be defined.
+An optional file may be listed multiple times with different options;
+if all of the options for any of the entries are satisfied,
+the module is included.
+.PP
+If a file is specified as a
+.IR device-driver ,
+any special compilation options for device drivers will be invoked.
+On the VAX this results in the use of the
+.B \-i
+option for the C optimizer.  This is required when pointer references
+are made to memory locations in the VAX I/O address space.
+.PP
+Two other optional keywords modify the usage of the file.
+.I Config
+understands that certain files are used especially for
+kernel profiling.  These files are indicated in the
+.I files
+files with a 
+.I profiling-routine
+keyword.  For example, the current profiling subroutines
+are sequestered off in a separate file with the following
+entry:
+.IP
+.nf
+.DT
+\fIsys/subr_mcount.c\fP	\fBoptional\fP	\fBprofiling-routine\fP
+.fi
+.LP
+The 
+.I profiling-routine
+keyword forces
+.I config
+not to compile the source file with the 
+.B \-pg
+option.
+.PP
+The second keyword which can be of use is the
+.I config-dependent
+keyword.  This causes
+.I config
+to compile the indicated module with the global configuration
+parameters.  This allows certain modules, such as
+.I machdep.c
+to size system data structures based on the maximum number
+of users configured for the system.
+.NH 2
+Adding device drivers to 4.4BSD
+.PP
+The I/O system and
+.I config
+have been designed to easily allow new device support to be added.
+The system source directories are organized as follows:
+.DS
+.TS
+lw(1.0i) l.
+/sys/h	machine independent include files
+/sys/sys	machine-independent system source files
+/sys/conf	site configuration files and basic templates
+/sys/net	network-protocol-independent, but network-related code
+/sys/netinet	DARPA Internet code
+/sys/netimp	IMP support code
+/sys/netns	Xerox NS code
+/sys/vax	VAX-specific mainline code
+/sys/vaxif	VAX network interface code
+/sys/vaxmba	VAX MASSBUS device drivers and related code
+/sys/vaxuba	VAX UNIBUS device drivers and related code
+.TE
+.DE
+.PP
+Existing block and character device drivers for the VAX 
+reside in ``/sys/vax'', ``/sys/vaxmba'', and ``/sys/vaxuba''.  Network
+interface drivers reside in ``/sys/vaxif''.  Any new device
+drivers should be placed in the appropriate source code directory
+and named so as not to conflict with existing devices.
+Normally, definitions for things like device registers are placed in
+a separate file in the same directory.  For example, the ``dh''
+device driver is named ``dh.c'' and its associated include file is
+named ``dhreg.h''.
+.PP
+Once the source for the device driver has been placed in a directory,
+the file ``/sys/conf/files.machine'', and possibly
+``/sys/conf/devices.machine'' should be modified.  The 
+.I files
+files in the conf directory contain a line for each C source or binary-only
+file in the system.  Those files which are machine independent are
+located in ``/sys/conf/files,'' while machine specific files
+are in ``/sys/conf/files.machine.''  The ``devices.machine'' file
+is used to map device names to major block device numbers.  If the device
+driver being added provides support for a new disk
+you will want to modify this file (the format is obvious).
+.PP
+In addition to including the driver in the
+.I files
+file, it must also be added to the device configuration tables.  These
+are located in ``/sys/vax/conf.c'', or similar for machines other than
+the VAX.  If you don't understand what to add to this file, you should
+study an entry for an existing driver. 
+Remember that the position in the
+device table specifies the major device number.
+The block major number is needed in the ``devices.machine'' file
+if the device is a disk.
+.PP
+With the configuration information in place, your configuration
+file appropriately modified, and a system reconfigured and rebooted
+you should incorporate the shell commands needed to install the special
+files in the file system to the file ``/dev/MAKEDEV'' or
+``/dev/MAKEDEV.local''.  This is discussed in the document ``Installing
+and Operating 4.4BSD''.

+APPENDIX B. RULES FOR DEFAULTING SYSTEM DEVICES
+.sp
+.R
+.NL
+.PP
+When \fIconfig\fP processes a ``config'' rule which does
+not fully specify the location of the root file system,
+paging area(s), device for system dumps, and device for
+argument list processing it applies a set of rules to
+define those values left unspecified.  The following list
+of rules are used in defaulting system devices.
+.IP 1) 3
+If a root device is not specified, the swap
+specification must indicate a ``generic'' system is to be built.
+.IP 2) 3
+If the root device does not specify a unit number, it
+defaults to unit 0.
+.IP 3) 3
+If the root device does not include a partition specification,
+it defaults to the ``a'' partition.
+.IP 4) 3
+If no swap area is specified, it defaults to the ``b''
+partition of the root device.
+.IP 5) 3
+If no device is specified for processing argument lists, the
+first swap partition is selected.
+.IP 6) 3
+If no device is chosen for system dumps, the first swap
+partition is selected (see below to find out where dumps are
+placed within the partition).
+.PP
+The following table summarizes the default partitions selected
+when a device specification is incomplete, e.g. ``hp0''.
+.DS
+.TS
+l l.
+Type	Partition
+_
+root	``a''
+swap	``b''
+args	``b''
+dumps	``b''
+.TE
+.DE
+.SH
+Multiple swap/paging areas
+.PP
+When multiple swap partitions are specified, the system treats the
+first specified as a ``primary'' swap area which is always used.
+The remaining partitions are then interleaved into the paging
+system at the time a
+.IR swapon (2)
+system call is made.  This is normally done at boot time with
+a call to
+.IR swapon (8)
+from the /etc/rc file.
+.SH
+System dumps
+.PP
+System dumps are automatically taken after a system crash,
+provided the device driver for the ``dumps'' device supports
+this.  The dump contains the contents of memory, but not
+the swap areas.  Normally the dump device is a disk in
+which case the information is copied to a location at the
+back of the partition.  The dump is placed in the back of the
+partition because the primary swap and dump device are commonly
+the same device and this allows the system to be rebooted without
+immediately overwriting the saved information.  When a dump has
+occurred, the system variable \fIdumpsize\fP 
+is set to a non-zero value indicating the size (in bytes) of
+the dump.  The \fIsavecore\fP\|(8)
+program then copies the information from the dump partition to
+a file in a ``crash'' directory and also makes a copy of the
+system which was running at the time of the crash (usually
+``/vmunix'').  The offset to the system dump is defined in the
+system variable \fIdumplo\fP (a sector offset from
+the front of the dump partition). The 
+.I savecore
+program operates by reading the contents of \fIdumplo\fP, \fIdumpdev\fP,
+and \fIdumpmagic\fP from /dev/kmem, then comparing the value
+of \fIdumpmagic\fP read from /dev/kmem to that located in
+corresponding location in the dump area of the dump partition.
+If a match is found, 
+.I savecore
+assumes a crash occurred and reads \fIdumpsize\fP from the dump area
+of the dump partition.  This value is then used in copying the

+.bp
+.LG
+.B
+.ce
+APPENDIX D. VAX KERNEL DATA STRUCTURE SIZING RULES
+.sp
+.R
+.NL
+.PP
+Certain system data structures are sized at compile time
+according to the maximum number of simultaneous users expected,
+while others are calculated at boot time based on the
+physical resources present, e.g. memory.  This appendix lists
+both sets of rules and also includes some hints on changing
+built-in limitations on certain data structures.
+.SH
+Compile time rules
+.PP
+The file \fI/sys/conf\|/param.c\fP contains the definitions of
+almost all data structures sized at compile time.  This file
+is copied into the directory of each configured system to allow
+configuration-dependent rules and values to be maintained.
+(Each copy normally depends on the copy in /sys/conf,
+and global modifications cause the file to be recopied unless
+the makefile is modified.)
+The rules implied by its contents are summarized below (here
+MAXUSERS refers to the value defined in the configuration file
+in the ``maxusers'' rule).
+Most limits are computed at compile time and stored in global variables
+for use by other modules; they may generally be patched in the system
+binary image before rebooting to test new values.
+.IP \fBnproc\fP
+.br
+The maximum number of processes which may be running at any time.
+It is referred to in other calculations as NPROC and is defined to be
+.DS
+20 + 8 * MAXUSERS
+.DE
+.IP \fBntext\fP
+.br
+The maximum number of active shared text segments.
+The constant is intended to allow for network servers and common commands
+that remain in the table.
+It is defined as
+.DS
+36 + MAXUSERS.
+.DE
+.IP \fBninode\fP
+.br
+The maximum number of files in the file system which may be
+active at any time.  This includes files in use by users, as 
+well as directory files being read or written by the system
+and files associated with bound sockets in the UNIX IPC domain.
+It is defined as
+.DS
+(NPROC + 16 + MAXUSERS) + 32
+.DE
+.IP \fBnfile\fP
+.br
+The number of ``file table'' structures.  One file
+table structure is used for each open, unshared, file descriptor.
+Multiple file descriptors may reference a single file table
+entry when they are created through a \fIdup\fP call, or as the
+result of a \fIfork\fP.  This is defined to be
+.DS
+16 * (NPROC + 16 + MAXUSERS) / 10 + 32
+.DE
+.IP \fBncallout\fP
+.br
+The number of ``callout'' structures.  One callout
+structure is used per internal system event handled with
+a timeout.  Timeouts are used for terminal delays,
+watchdog routines in device drivers, protocol timeout processing, etc.
+This is defined as
+.DS
+16 + NPROC
+.DE
+.IP \fBnclist\fP
+.br
+The number of ``c-list'' structures.  C-list structures are
+used in terminal I/O, and currently each holds 60 characters.
+Their number is defined as
+.DS
+60 + 12 * MAXUSERS
+.DE
+.IP \fBnmbclusters\fP
+.br
+The maximum number of pages which may be allocated by the network.  
+This is defined as 256 (a quarter megabyte of memory) in /sys/h/mbuf.h.
+In practice, the network rarely uses this much memory.  It starts off
+by allocating 8 kilobytes of memory, then requesting more as 
+required.  This value represents an upper bound.
+.IP \fBnquota\fP
+.br
+The number of ``quota'' structures allocated.  Quota structures
+are present only when disc quotas are configured in the system.  One
+quota structure is kept per user.  This is defined to be
+.DS
+(MAXUSERS * 9) / 7 + 3
+.DE
+.IP \fBndquot\fP
+.br
+The number of ``dquot'' structures allocated.  Dquot structures
+are present only when disc quotas are configured in the system.
+One dquot structure is required per user, per active file system quota.
+That is, when a user manipulates a file on a file system on which
+quotas are enabled, the information regarding the user's quotas on
+that file system must be in-core.  This information is cached, so
+that not all information must be present in-core all the time.
+This is defined as
+.DS
+NINODE + (MAXUSERS * NMOUNT) / 4
+.DE
+where NMOUNT is the maximum number of mountable file systems.
+.LP
+In addition to the above values, the system page tables (used to
+map virtual memory in the kernel's address space) are sized at
+compile time by the SYSPTSIZE definition in the file /sys/vax/vmparam.h.
+This is defined to be
+.DS
+20 + MAXUSERS
+.DE
+pages of page tables. 
+Its definition affects
+the size of many data structures allocated at boot time because
+it constrains the amount of virtual memory which may be addressed
+by the running system.  This is often the limiting factor
+in the size of the buffer cache, in which case a message is printed
+when the system configures at boot time.
+.SH
+Run-time calculations
+.PP
+The most important data structures sized at run-time are those used in
+the buffer cache.  Allocation is done by allocating physical memory
+(and system virtual memory) immediately after the system
+has been started up; look in the file /sys/vax/machdep.c.
+The amount of physical memory which may be allocated to the buffer
+cache is constrained by the size of the system page tables, among
+other things.  While the system may calculate
+a large amount of memory to be allocated to the buffer cache,
+if the system page
+table is too small to map this physical
+memory into the virtual address space
+of the system, only as much as can be mapped will be used.
+.PP
+The buffer cache is comprised of a number of ``buffer headers''
+and a pool of pages attached to these headers.  Buffer headers
+are divided into two categories: those used for swapping and
+paging, and those used for normal file I/O.  The system tries
+to allocate 10% of the first two megabytes and 5% of the remaining
+available physical memory for the buffer
+cache (where \fIavailable\fP does not count that space occupied by
+the system's text and data segments).  If this results in fewer
+than 16 pages of memory allocated, then 16 pages are allocated.
+This value is kept in the initialized variable \fIbufpages\fP
+so that it may be patched in the binary image (to allow tuning
+without recompiling the system),
+or the default may be overridden with a configuration-file option.
+For example, the option \fBoptions BUFPAGES="3200"\fP
+causes 3200 pages (3.2M bytes) to be used by the buffer cache.
+A sufficient number of file I/O buffer headers are then allocated
+to allow each to hold 2 pages each.
+Each buffer maps 8K bytes.
+If the number of buffer pages is larger than can be mapped
+by the buffer headers, the number of pages is reduced.
+The number of buffer headers allocated
+is stored in the global variable \fInbuf\fP,
+which may be patched before the system is booted.
+The system option \fBoptions NBUF="1000"\fP forces the allocation
+of 1000 buffer headers.
+Half as many swap I/O buffer headers as file I/O buffers
+are allocated,
+but no more than 256.
+.SH
+System size limitations
+.PP
+As distributed, the sum of the virtual sizes of the core-resident
+processes is limited to 256M bytes.  The size of the text
+segment of a single process is currently limited to 6M bytes.
+It may be increased to no greater than the data segment size limit
+(see below) by redefining MAXTSIZ.
+This may be done with a configuration file option,
+e.g. \fBoptions MAXTSIZ="(10*1024*1024)"\fP
+to set the limit to 10 million bytes.
+Other per-process limits discussed here may be changed with similar options
+with names given in parentheses.
+Soft, user-changeable limits are set to 512K bytes for stack (DFLSSIZ)
+and 6M bytes for the data segment (DFLDSIZ) by default;
+these may be increased up to the hard limit
+with the \fIsetrlimit\fP\|(2) system call.
+The data and stack segment size hard limits are set by a system configuration
+option to one of 17M, 33M or 64M bytes.
+One of these sizes is chosen based on the definition of MAXDSIZ;
+with no option, the limit is 17M bytes; with an option
+\fBoptions MAXDSIZ="(32*1024*1024)"\fP (or any value between 17M and 33M),
+the limit is increased to 33M bytes, and values larger than 33M
+result in a limit of 64M bytes.
+You must be careful in doing this that you have adequate paging space.
+As normally configured , the system has 16M or 32M bytes per paging area,
+depending on disk size.
+The best way to get more space is to provide multiple, thereby
+interleaved, paging areas.
+Increasing the virtual memory limits results in interleaving of
+swap space in larger sections (from 500K bytes to 1M or 2M bytes).
+.PP
+By default, the virtual memory system allocates enough memory
+for system page tables mapping user page tables
+to allow 256 megabytes of simultaneous active virtual memory.
+That is, the sum of the virtual memory sizes of all (completely- or partially-)
+resident processes can not exceed this limit.
+If the limit is exceeded, some process(es) must be swapped out.
+To increase the amount of resident virtual space possible,
+you can alter the constant USRPTSIZE (in
+/sys/vax/vmparam.h).
+Each page of system page tables allows 8 megabytes of user virtual memory.
+.PP
+Because the file system block numbers are stored in
+page table \fIpg_blkno\fP
+entries, the maximum size of a file system is limited to
+2^24 1024 byte blocks.  Thus no file system can be larger than 8 gigabytes.
+.PP
+The number of mountable file systems is set at 20 by the definition
+of NMOUNT in /sys/h/param.h.
+This should be sufficient; if not, the value can be increased up to 255.
+If you have many disks, it makes sense to make some of
+them single file systems, and the paging areas don't count in this total.
+.PP
+The limit to the number of files that a process may have open simultaneously
+is set to 64.
+This limit is set by the NOFILE definition in /sys/h/param.h.
+It may be increased arbitrarily, with the caveat that the user structure
+expands by 5 bytes for each file, and thus UPAGES (/sys/vax/machparam.h)
+must be increased accordingly.
+.PP
+The amount of physical memory is currently limited to 64 Mb
+by the size of the index fields in the core-map (/sys/h/cmap.h).
+The limit may be increased by following instructions in that file
+to enlarge those fields.

+APPENDIX E. NETWORK CONFIGURATION OPTIONS
+.sp
+.R
+.NL
+.PP
+The network support in the kernel is self-configuring
+according to the protocol support options (INET and NS) and the network
+hardware discovered during autoconfiguration.
+There are several changes that may be made to customize network behavior
+due to local restrictions.
+Within the Internet protocol routines, the following options
+set in the system configuration file are supported:
+.IP \fBGATEWAY\fP
+.br
+The machine is to be used as a gateway.
+This option currently makes only minor changes.
+First, the size of the network routing hash table is increased.
+Secondly, machines that have only a single hardware network interface
+will not forward IP packets; without this option, they will also refrain
+from sending any error indication to the source of unforwardable packets.
+Gateways with only a single interface are assumed to have missing
+or broken interfaces, and will return ICMP unreachable errors to hosts
+sending them packets to be forwarded.
+.IP \fBTCP_COMPAT_42\fP
+.br
+This option forces the system to limit its initial TCP sequence numbers
+to positive numbers.
+Without this option, 4.4BSD systems may have problems with TCP connections
+to 4.2BSD systems that connect but never transfer data.
+The problem is a bug in the 4.2BSD TCP.
+.IP \fBIPFORWARDING\fP
+.br
+Normally, 4.4BSD machines with multiple network interfaces
+will forward IP packets received that should be resent to another host.
+If the line ``options IPFORWARDING="0"'' is in the system configuration
+file, IP packet forwarding will be disabled.
+.IP \fBIPSENDREDIRECTS\fP
+.br
+When forwarding IP packets, 4.4BSD IP will note when a packet is forwarded
+using the same interface on which it arrived.
+When this is noted, if the source machine is on the directly-attached
+network, an ICMP redirect is sent to the source host.
+If the packet was forwarded using a route to a host or to a subnet,
+a host redirect is sent, otherwise a network redirect is sent.
+The generation of redirects may be inhibited with the configuration
+option ``options IPSENDREDIRECTS="0".''
+.br
+.IP \fBSUBNETSARELOCAL\fP
+TCP calculates a maximum segment size to use for each connection,
+and sends no datagrams larger than that size.
+This size will be no larger than that supported on the outgoing
+interface.
+Furthermore, if the destination is not on the local network,
+the size will be no larger than 576 bytes.
+For this test, other subnets of a directly-connected subnetted
+network are considered to be local unless the line
+``options SUBNETSARELOCAL="0"'' is used in the system configuration file.
+.LP
+The following options are supported by the Xerox NS protocols:
+.IP \fBNSIP\fP
+.br
+This option allows NS IDP datagrams to be encapsulated in Internet IP
+packets for transmission to a collaborating NSIP host.
+This may be used to pass IDP packets through IP-only link layer networks.
+See
+.IR nsip (4P)
+for details.
+.IP \fBTHREEWAYSHAKE\fP
+.br
+The NS Sequenced Packet Protocol does not require a three-way handshake
+before considering a connection to be in the established state.
+(A three-way handshake consists of a connection request, an acknowledgement
+of the request along with a symmetrical opening indication,
+and then an acknowledgement of the reciprocal opening packet.)
+This option forces a three-way handshake before data may be transmitted
+on Sequenced Packet sockets.

+.Nm config
+.Nd build system configuration files
+.Sh SYNOPSIS
+.Nm config
+.Op Fl p
+.Ar system_name
+.Sh DESCRIPTION
+.Pp
+This is the old version of the
+.Nm config
+program.
+It understands the old autoconfiguration scheme
+used on the HP300, DECstation, and derivative platforms.
+The new version of config is used with the
+SPARC and i386 platforms.
+Only the version of 
+.Nm config
+applicable to the architecture that you are running
+will be installed on your machine.
+.Pp
+.Nm Config
+builds a set of system configuration files from the file
+.Ar SYSTEM_NAME
+which describes
+the system to configure.
+A second file
+tells
+.Nm config
+what files are needed to generate a system and
+can be augmented by configuration specific set of files
+that give alternate files for a specific machine.
+(see the
+.Sx FILES
+section below)
+.Pp
+Available option and operand:
+.Pp
+.Bl -tag -width SYSTEM_NAME
+.It Fl p
+If the
+.Fl p
+option is supplied, 
+.Nm config
+will configure a system for profiling; for example,
+.Xr kgmon 8
+and
+.Xr gprof 1 .
+.It Ar SYSTEM_NAME
+specifies the name of the system configuration file
+containing device specifications, configuration options
+and other system parameters for one system configuration.
+.El
+.Pp
+.Nm Config
+should be run from the
+.Pa conf
+subdirectory of the system source (usually
+.Pa /sys/conf ) .
+.Nm Config
+assumes the directory
+.Pa ../SYSTEM_NAME
+exists and places all output files there.  
+The output of
+.Nm config
+consists of a number of files; for the
+.Tn VAX ,
+they are:
+.Pa ioconf.c ,
+a description
+of what I/O devices are attached to the system;
+.Pa ubglue.s ,
+a set of interrupt service routines for devices
+attached to the
+.Tn UNIBUS ;
+.Pa ubvec.s ,
+offsets into a structure used for counting per-device interrupts;
+.Pa Makefile ,
+used by
+.Xr make 1
+in building the system;
+header files,
+definitions of
+the number of various devices that will be compiled into the system;
+swap configuration files,
+definitions for
+the disk areas to be used for swapping, the root file system,
+argument processing, and system dumps.
+.Pp
+After running
+.Nm config ,
+it is necessary to run
+.Dq Li make depend
+in the directory where the new makefile
+was created.
+.Nm Config
+prints a reminder of this when it completes.
+.Pp
+If any other error messages are produced by
+.Nm config ,
+the problems in the configuration file should be corrected and
+.Nm config
+should be run again.
+Attempts to compile a system that had configuration errors
+are likely to fail.
