The `c' command is used to create a unix configuration file. The `c' command
prompts for the configuration name, the default name is `unix'. The config-
uration process involves answering a series questions about the processor,
peripheral devices, and system parameters. These questions consist of the
question itself followed by an item or list of items enclosed in < >. A single
item enclosed in < > is the default answer to the question, to use the default
answer, type only a return. A list of items enclosed in < > represents a
multiple choice answer to the question, select one item from the list as the
answer, type that item then return. These questions have no default answer.
To obtain help with answering a question, respond to the question with a `?'
followed by a return. A help message will be printed and the question will be
repeated. Typing a `control c' at any time during the configuration creation
process will abort the creation of the configuration and return to the `>'
command prompt. Typing a `control d' in response to a question will cause
SYSGEN to abort that question and backup to the previous question. Backing up
with `control d' can cause large amounts of configuration information to be
erased, for example, backing up from the magtapes question to the disks question
will cause all previously entered disks to be erased from the configuration.
Certain questions, such as the types of disks on a controller, require multiple
answers. For those questions, the question will be repeated until answered with
only a return.
> c
To backup to the previous question, type `control d' !
Answer any question with a `?' followed by a return for help !
Configuration name <unix> ? ?
The default configuration name is `unix', to use the default name type a
return. Otherwise, type the desired configuration name, up to a maximum of
eight characters, followed by a return.
Configuration name <unix> ? unix
Processor type:
< 23 24 34 40 44 45 55 60 70 > ? ?
Select the appropriate CPU type from the list and type that number followed by
a return. Actually there are only two versions of the unix operating system,
one for CPUs with separate Instruction and data space and one for those CPUs
without separate I & D space. All other CPU differences are handled dynamically
and do not require that a unix kernel be generated specifically for each CPU
type. If the target CPU is not listed pick the CPU type from the list that
most closely resembles it. If the target CPU has separate I & D space, pick
from PDP11/44, 45, 55, or 70. Otherwise chose from PDP11/23, 24, 34, 40, or 60.
The Micro PDP11 is an 11/23 processor.
Processor type:

Disk controller type:
< rh11 rh70 rp11 rk611 rk711 rl11 rx211 rk11 uda50 rqdx1 > ? ?
Specify a disk controller by typing one of the names from the list of disk
controllers followed by a return. SYSGEN will ask several questions about the
controller and the disk drives connected to it. After these questions have been
answered SYSGEN will prompt for the next disk controller type. Enter the name
of the next disk controller or type a return to terminate the list of disk
controllers. In order to expedite the disk controller specification process
the system disk controller should be entered first.

Drive 0 type < rx50 rd51 > ? ?
After the disk controller type has been specified, the type of each disk drive
on that controller, in order starting with drive zero, will be requested. Enter
one of the drive types from the list followed by a return. Type only a return to
terminate the list of disk drives. SYSGEN assumes that the disk drive numbers
will be in order starting from zero, i.e., if three drives are present they will
be numbered 0, 1, 2. To allow for non sequential numbering of drives, a drive
type may be entered even if the drive does not exist. The system will ignore the
nonexistent drives. For example, if three RP06 disks were to be numbered 0, 1,
and 4, drives two and three would also be specified as RP06 disks. Drives two
and three will be ignored, however space for them is the system's disk driver
information tables will be reserved and therefore wasted.
Drive 0 type < rx50 rd51 > ? rd51
Drive 1 type < rx50 rd51 > ? rx50
Drive 2 type < rx50 rd51 > ? rx50
Drive 3 type < rx50 rd51 > ? [Return]
CSR address <172150> ? ?
The number enclosed in < > is the default CSR address for the device, type a
return to use the default address. To specify a nonstandard CSR address, type
that address followed by a return. Only octal addresses are allowed.
CSR address <172150> ? [Return]
Vector address <154> ? ?
The number enclosed in < > is the default interrupt vector address for the
device, type a return to use the default vector address. To specify a non-
standard vector, type the vector address followed by a return. Only octal
vector addresses are allowed.
Vector address <154> ? [Return]
Is the system disk on this controller <yes> ? ?
If the system disk is connected to this controller, answer yes followed by a
return or just a return. The system disk is where the Unix operating system
resides, i.e., the disk onto which the Unix ROOT file system was loaded from
the distribution tape. If the system disk is not on this controller, type no
followed by a return.
Is the system disk on this controller <yes> ? yes
System disk unit number <0> ? ?
To use the default system disk unit number of zero, type return. To specify an
alternate system disk unit number, type that number followed by a return. If the
system disk is other than unit zero, the following changes will be required:
1. Most hardware boot ROMs will only boot from unit zero.
The system may be bootstrapped by loading the secondary boot
program from the distribution magtape.
2. The boot file specification must be changed to reflect the
system disk unit number, i.e., hp(2,0)unix.
3. The file `/etc/fstab' must be edited to incorporate the new
file system names, see fstab(5).
4. The special file `/dev/swap' must be recreated, so that the ps(1)
command can access the swap area, see `/dev/makefile'.
System disk unit number <0> ? 0
Disk controller type:
< rh11 rh70 rp11 rk611 rk711 rl11 rx211 rk11 uda50 rqdx1 > ? [Return]
Use standard placement of root, swap, and error log <yes> ? ?
The sysgen program contains tables which define the standard locations of the
Unix ROOT, SWAP, and ERROR LOG file systems on each type of disk. To use the
default placements of these file systems, type yes followed by a return or just
a return. To specify alternate placements of the file systems, answer no
followed by a return. It is strongly recommended that the standard placements be
used for the initial system generation and that reliable system operation be
established prior to experimenting with alternate placements.
If this question is answered no, the sysgen program will ask a series of
questions about the desired placement of the ROOT, PIPE, SWAP, and ERROR LOG
file systems. Along with each question the program will print a default value,
which may be used or modified as desired. WARNING, the sysgen program accepts
the answers to these questions blindly and does not check them !
The following hints may be helpful:
1. Placing ROOT and SWAP on separate disk controllers will increase
system I/O performance. Placing ROOT and SWAP on separate drives
on the same controller is of little benefit.
2. The PIPE minor device should always equal the ROOT minor device.
3. All four of the file systems may exist within the same disk partition.
However, care must be taken to insure that there is no file system
overlap, use the standard placements for the RL02 as a guide.
4. The `mkconf' program, which is called by sysgen, does some checking
of the file system placements and prints warnings about overlap.
Use standard placement of root, swap, and error log <yes> ? yes
Magtape controller:
< tm02 tm03 tm11 ts11 tsv05 tc11 > ? ?
Select the magtape controller type from the list and enter that name followed
by a return. Multiple magtape controllers may be specified, however only one
controller of each type may be specified. For each magtape controller entered,
several questions about the controller and its drives will be asked. After
answering these questions, type the name of the next magtape controller or a
return to end the list of controllers.

Magtape controller:
< tm02 tm03 tm11 ts11 tsv05 tc11 > ? tsv05
Number of magtape units <1> ? ?
Enter the number of magtape units connected to the controller followed by a
return. The default number of units is one, type return to use the default.
The drive type for magtape units is not required by SYSGEN. SYSGEN expects
the tape units to be numbered sequentially, i.e., a controller with three
drives connected to it would have those drives numbered 0, 1, 2. If non-
sequential drive numbering is desired, set the number of drives to one greater
than the highest numbered unit. The system will ignore the nonexistent units,
however space for those tape units in the system's driver tables will be wasted.
Number of magtape units <1> ? 1
CSR address <172520> ? ?
The number enclosed in < > is the default CSR address for the device, type a
return to use the default address. To specify a nonstandard CSR address, type
that address followed by a return. Only octal addresses are allowed.
CSR address <172520> ? [Return]
Vector address <224> ? ?
The number enclosed in < > is the default interrupt vector address for the
device, type a return to use the default vector address. To specify a non-
standard vector, type the vector address followed by a return. Only octal
vector addresses are allowed.
Vector address <224> ? [Return]
Use this magtape for crash dumps <yes> ? ?
Unix does crash dumps by writing an image of memory to a magtape. Answering
yes followed by a return or just a return to this question will designate
the current magtape controller as the crash dump device. If the question is
answered no, it will be repeated for each magtape controller specified until
a yes answer is received. Only on magtape controller can be selected for taking
crash dumps. The crash dump will always be written to unit zero on the magtape
controller that is selected for crash dumps.
For RL02 or RD51 based systems, crash dumps will be written to the swap area
of the system disk. This assumes that there is no magtape present of the system.
Use this magtape for crash dumps <yes> ? no
Magtape controller:
< tm02 tm03 tm11 ts11 tsv05 tc11 > ? [Return]
Crash dumps to RD51 unit 0 (swap area)

Communications devices:
< dz dzv dh dhdm du dn kl dl > ? ?
Enter the name of one of the communications devices listed followed by a return,
answer the questions about that device, then enter the name of the next device
or a return to terminate the list of devices.
The communications devices are specified by their Unix names:
NAME DEVICE COMMENTS

kl DL11/DLV11 (CSR 776500) single line unit
dl DL11/DLV11 (CSR 775610) single line unit
The first `kl' unit is reserved for the console terminal. The console is always
present, do not count it in the `kl' specification. Use the `kl' and `dl' names
for the equivalent Q bus devices.
Communications devices:
< dz dzv dh dhdm du dn kl dl > ? dzv
Number of units <1> ? ?
Enter the number of communication device units followed by a return, or type
a return to use the default number of one unit. The `d' command may be used
to print a list of the devices and the maximum number of units allowed for each
device.
Number of units <1> ? 1
CSR address <160100> ? ?
The number enclosed in < > is the default CSR address for the device, type a
return to use the default address. To specify a nonstandard CSR address, type
that address followed by a return. Only octal addresses are allowed.
CSR address <160100> ? [Return]
Vector address <300> ? ?
The number enclosed in < > is the default interrupt vector address for the
device, type a return to use the default vector address. To specify a non-
standard vector, type the vector address followed by a return. Only octal
vector addresses are allowed.
Vector address <300> ? [Return]
Communications devices:
< dz dzv dh dhdm du dn kl dl > ? [Return]
Include C/A/T phototypesetter driver <no> ? ?
Please answer yes or no !
? no
User devices:
< u1 u2 u3 u4 > ? ?
Up to four user devices may be configured into the V7M-11 operating system.
The driver code for the user device must be edited into one of the four user
device driver prototype files (u1.c u2.c u3.c u4.c) in the /sys/dev directory.
The user device driver prototype files define the interface to the operating
system the user must supply the code to operate the device.
If there are no user devices type just a return. If user devices are to be
configured, type the name of the device followed by a return. The sysgen program
will ask for the CSR address and vector address of the device. If there is
another user device to be configured type its name followed by a return, if not
type just a return.
User devices:
< u1 u2 u3 u4 > ? [Return]
Include packet driver <no> ? ?
Type yes followed by a return to include the packet driver. Type no followed
by a return or just a return to omit the packer driver. For more information
about the packet protocol driver refer to pkon(2), pkopen(3), and pk(4) in the
"Unix Programmer`s Manual".
The packet driver is not a supported feature of V7M-11, refer to section 4.21
of the V7M-11 Software Technical Description for more information.
Include packet driver <no> ? no
Include multiplexed files support <no> ? ?
Type yes followed by a return to include multiplexed files support. Type no
followed by a return or just a return to omit multiplexed files support. For
more information about multiplexed files refer to mpx(2) and mpxio(5) in the
"Unix Programmer's Manual".
Multiplexed files is not a supported feature of V7M-11, refer to section 4.21
of the V7M-11 Software Technical Description for more information.
Include multiplexed files support <no> ? no
Use standard system parameters <yes> ? ?
The Unix operating has a number of parameters, used to adjust the sizes of its
internal data structures to match the number of users on the system. The sysgen
program contains a set of standard values for these parameters. Is is highly
recommended that the standard values be used for the initial system generation.
Experimentation with the parameters should be postponed until the initial
system has been installed and reliable operation verified. To use the standard
values respond the the question with a return. If the question is answered no,
the sysgen program will prompt for the value of each parameter. The name of
the parameter and its standard value will be printed. Type return to use the
standard value or type the new value followed by a return. The parameters are:
PARAM OV_VAL ID_VAL COST COMMENT
NBUF 16 29 542 (OV = 30) buffer cache size
NINODE 100 200 74 inode table size

Line frequency in hertz <60> ? 50
Timezone (hours ahead of GMT) <5=EST 6=CST 7=MST 8=PST> ? ?
The timezone ,in which the system will be operating, must be specified as the
number of hours ahead of GMT (Greenwich Mean Time). For example, Eastern
standard time is five hours ahead of GMT. Do NOT include daylight savings time
in the timezone specification.
Timezone (hours ahead of GMT) <5=EST 6=CST 7=MST 8=PST> ? 0
Does your area use daylight savings time <yes> ? ?
If the timezone in which unix is to operate uses daylight savings time, answer
yes followed by a return or just a return. Otherwise type no followed by a
return. If the question is answered yes, unix will automatically compensate
for daylight savings time.
Does your area use daylight savings time <yes> ? yes
