    NAME

    monitor - SPARC system PROM monitor
     
    

    SYNOPSIS

    STOP-A
    

    BREAK
    

    initial system power-on
    

    exit from a client program, e.g., the Operating System
    

     

    DESCRIPTION

    The CPU board of a workstation contains one or more EPROMs or EEPROMs. The program which executes from the PROMs is referred to as "the monitor". Among other things, the monitor performs system initialization at power-on and provides a user interface.  

    Monitor Prompt

    The monitor of earlier workstations was known as the SunMON monitor and displayed the > for its prompt. See the SunMON MONITOR USAGE section for further details.

    Existing workstations use a monitor which is known as the OpenBoot monitor. The OpenBoot monitor typically displays ok as its prompt, but it may also display the > prompt under certain circumstances.

    If the 'auto-boot?' NVRAM parameter is set to 'false' when the workstation is powered on, the system does not attempt to boot and the monitor issues its prompt. If 'auto-boot' is set to 'true', the system initiates the boot sequence. The boot sequence can be aborted by simultaneously pressing two keys on the system's keyboard: L1 and A (on older keyboards), or Stop and A (on newer keyboards). Either a lower case a or an upper case A works for the keyboard abort sequence. If a console has been attached by way of one of the system's serial ports then the abort sequence can be accomplished by sending a BREAK. See tip(1).

    When the NVRAM 'security-mode' parameter has been turned on, or when the value of the 'sunmon-compat?' parameter is true, then the OpenBoot monitor displays the message: Type b (boot), c (continue), or n (new command mode)

    and the > prompt appears.  

    OPENBOOT PROM USAGE

    Some of the more useful commands that can be issued from OpenBoot's ok prompt are described here. Refer to the book for a complete list of commands.  

    Help

    Help for various functional areas of the OpenBoot monitor can be obtained by typing help. The help listing provides a number of other key words which can then be used in the help command to provide further details.  

    NVRAM Parameters

    Each workstation contains one or more NVRAM devices which contains unique system ID information, as well as a set of user-configurable parameters. The NVRAM parameters allow the user a certain level of flexibility in configuring the system to act in a given manner under a specific set of circumstances.

    See eeprom(1M) for a description of the parameters and information regarding setting the parameters from the OS level.

    The following commands can be used at the OpenBoot monitor to access the NVRAM parameters.

    printenv

    Used to list the NVRAM parameters, along with their default values and current values.

    setenv pn pv

    Used to set or modify a parameter. The pn represents the parameter name, and pv represents the parameter value.

    set-default pn

    Used to set an individual parameter back to its default value.

    set-defaults

    Used to reset all parameters to their default values. (Note that 'set-defaults' only affects parameters that have assigned default values.)

     

    Security Parameters

    Newer OpenBoot monitors contain user interfaces that support the storage and listing of keys for later use by client programs.

    list-security-keys

    Lists the names of keys currently stored on a machine.

    set-security-key keyname [ keydata ]

    Stores key data keydata in a key named keyname. Actual key data can be up to 32 bytes in length. The maximum length of keyname is 64 bytes, which allows for the hex-formatted ASCII used to present the key data. If keydata is not present, keyname and its corresponding data is deleted.

     

    Hardware Checks and Diagnostics

    The following commands are available for testing or checking the system's hardware. If the 'diag-switch?' NVRAM parameter is set to true when the system is powered on, then a Power-On Self Test (POST) diagnostic is run, if present, sending its results messages to the system's serial port A. Not all of the commands shown are available on all workstations.

    test-all

    Run the diagnostic tests on each device which has provided a self-test.

    test floppy

    Run diagnostics on the system's floppy device.

    test /memory

    Run the main memory tests. If the NVRAM parameter 'diag-switch?' is set to true, then all of main memory is tested. If the parameter is false then only the amount of memory specified in the 'selftest-#megs' NVRAM parameter is tested.

    test net

    Test the network connection for the on-board network controller.

    watch-net

    Monitor the network attached to the on-board net controller.

    watch-net-all

    Monitor the network attached to the on-board net controller, as well as the network controllers installed in SBus slots.

    watch-clock

    Test the system's clock function.

     

    System Information

    The following commands are available for displaying information about the system. Not all commands are available on all workstations.

    banner

    Display the power-on banner.

    .enet-addr

    Display the system's Ethernet address.

    .idprom

    Display the formatted contents of the IDPROM.

    module-info

    Display information about the system's processor(s).

    probe-scsi

    Identify the devices attached to the on-board SCSI controller.

    probe-scsi-all

    Identify the devices attached to the on-board SCSI controller as well as those devices which are attached to SBus SCSI controllers.

    show-disks

    Display a list of the device paths for installed SCSI disk controllers.

    show-displays

    Display a list of the device paths for tty devices.

    .traps

    Display a list of the SPARC trap types.

    .version

    Display the version and date of the OpenBoot PROM.

     

    Emergency Commands

    These commands must be typed from the keyboard, they do not work from a console which is attached by way of the serial ports. With the exception of the Stop-A command, these commands are issued by pressing and holding down the indicated keys on the keyboard immediately after the system has been powered on. The keys must be held down until the monitor has checked their status. The Stop-A command can be issued at any time after the console display begins, and the keys do not need to be held down once they've been pressed. The Stop-D, Stop-F and Stop-N commands are not allowed when one of the security modes has been set. Not all commands are available on all workstations.

    Stop (L1)

    Bypass the Power-On Self Test (POST). This is only effective if the system has been placed into the diagnostic mode.

    Stop-A (L1-A)

    Abort the current operation and return to the monitor's default prompt.

    Stop-D (L1-D)

    Set the system's 'diag-switch?' NVRAM parameter to 'true', which places the system in diagnostic mode. POST diagnostics, if present, are run, and the messages are displayed by way of the system's serial port A.

    Stop-F (L1-F)

    Enter the OpenBoot monitor before the monitor has probed the system for devices. Issue the 'fexit' command to continue with system initialization.

    Stop-N (L1-N)

    Causes the NVRAM parameters to be reset to their default values. Note that not all parameters have default values.

     

    Line Editor Commands

    The following commands can be used while the monitor is displaying the ok prompt. Not all of these editing commands are available on all workstations.

    CTRL-A

    Place the cursor at the start of line.

    CTRL-B

    Move the cursor backward one character.

    ESC-B

    Move the cursor backward one word.

    CTRL-D

    Erase the character that the cursor is currently highlighting.

    ESC-D

    Erase the portion of word from the cursor's present position to the end of the word.

    CTRL-E

    Place the cursor at the end of line.

    CTRL-F

    Move the cursor forward one character.

    ESC-F

    Move the cursor forward one word.

    CTRL-H

    Erase the character preceding the cursor (also use Delete or Back Space)

    ESC-H

    Erase the portion of the word which precedes the cursor (use also CTRL-W)

    CTRL-K

    Erase from the cursor's present position to the end of the line.

    CTRL-L

    Show the command history list.

    CTRL-N

    Recall the next command from the command history list

    CTRL-P

    Recall a previous command from the command history list.

    CTRL-Q

    Quote the next character (used to type a control character).

    CTRL-R

    Retype the current line.

    CTRL-U

    Erase from the cursor's present position to the beginning of the line.

    CTRL-Y

    Insert the contents of the memory buffer into the line, in front (to the left) of the cursor.

     

    nvramrc

    The nvramrc is an area of the system's NVRAM where users may store Forth programs. The programs which are stored in the nvramrc are executed each time the system is reset, provided that the 'use-nvramrc?' NVRAM parameter has been set to 'true'. Refer to the book for information on how to edit and use the nvramrc.  

    Restricted Monitor

    The command 'old-mode' is used to move OpenBoot into a restricted monitor mode, causing the > prompt to be displayed. Only three commands are allowed while in the restricted monitor; the 'go' command (to resume a program which was interrupted with the Stop-A command), the 'n' command (to return to the normal OpenBoot monitor), and boot commands. The restricted monitor's boot commands approximate the older SunMON monitor's boot command syntax. If a 'security-mode' has been turned on then the restricted monitor becomes the default monitor environment. The restricted monitor may also become the default environment if the 'sunmon-compat?' NVRAM parameter is set to true. Not all workstations have the 'sunmon-compat?' parameter.  

    SUNMON PROM USAGE

    The following commands are available systems with older SunMON-based PROM:

    +|-

    Increment or decrement the current address and display the contents of the new location.

    ^C source destination n

    (caret-C) Copy, byte-by-byte, a block of length n from the source address to the destination address.

    ^I program

    (caret-I) Display the compilation date and location of program.

    ^T virtual_address

    (caret-T) Display the physical address to which virtual_address is mapped.

    b [ ! ] [ device [ (c,u,p) ] ] [ pathname ] [ arguments_list ]

    b[?]

    Reset appropriate parts of the system and bootstrap a program. A `!' (preceding the device argument) prevents the system reset from occurring. Programs can be loaded from various devices (such as a disk, tape, or Ethernet). `b' with no arguments causes a default boot, either from a disk, or from an Ethernet controller. `b?' displays all boot devices and their devices.

    c [virtual_address]

    Resume execution of a program. When given, virtual_address is the address at which execution resumes. The default is the current PC. Registers are restored to the values shown by the d, and r commands.

    d [window_number]

    Display (dump) the state of the processor. The processor state is observable only after:
    o An unexpected trap was encountered.
    o A user program dropped into the monitor (by calling abortent).
    o The user manually entered the monitor by typing L1-A or BREAK.
    The display consists of the following:
    o The special registers: PSR, PC, nPC, TBR, WIM, and Y
    o Eight global registers
    o 24 window registers (8 in, 8 local, and 8 out), corresponding to one of the 7 available windows. If a Floating-Point Unit is on board, its status register along with 32 floating-point registers are also shown.

    window_number

    Display the indicated window_number, which can be any value between 0 and 6, inclusive. If no window is specified and the PSR's current window pointer contains a valid window number, registers from the window that was active just prior to entry into the monitor are displayed. Otherwise, registers from window 0 are displayed.

    e [virtual_address][action] ...

    Open the 16-bit word at virtual_address (default zero). The address is interpreted in the address space defined by the s command. See the a command for a description of action.

    f virtual_address1 virtual_address2 pattern [size]

    Fill the bytes, words, or long words from virtual_address1 (lower) to virtual_address2 (higher) with the constant, pattern. The size argument can take one of the following values:

    b

    byte format (the default)

    w

    word format

    l

    long word format

    For example, the following command fills the address block from 0x1000 to 0x2000 with the word pattern, 0xABCD:

    f 1000 2000 ABCD W

    g [vector] [argument]
    g [virtual_address] [argument]

    Goto (jump to) a predetermined or default routine (first form), or to a user-specified routine (second form). The value of argument is passed to the routine. If the vector or virtual_address argument is omitted, the value in the PC is used as the address to jump to.

    To set up a predetermined routine to jump to, a user program must, prior to executing the monitor's g command, set the variable *romp->v_vector_cmd to be equal to the virtual address of the desired routine. Predetermined routines need not necessarily return control to the monitor.

    The default routine, defined by the monitor, prints the user-supplied vector according to the format supplied in argument. This format can be one of:

    %x

    hexadecimal

    %d

    decimal

    g0

    Force a panic and produce a crash dump when the monitor is running as a result of the system being interrupted,

    g4

    (Sun-4 systems only) Force a kernel stack trace when the monitor is running as a result of the system being interrupted,

    h

    Display the help menu for monitor commands and their descriptions. To return to the monitor's basic command level, press ESCAPE or q before pressing RETURN.

    With no arguments, display the current I/O device characteristics including: current input device, current output device, baud rates for serial ports A and B, an input-to-output echo indicator, and virtual addresses of mapped UART devices. With arguments, set or configure the current I/O device. With the u argument (uu...), set the I/O device to be the virtual_address of a UART device currently mapped.

    echo


     Can be either e to enable input to be echoed to the output device, or ne, to indicate that input is not echoed.

    port

    Assign the indicated port to be the current I/O device. port can be one of:

    a

    serial port A

    b

    serial port B

    k

    the workstation keyboard

    s

    the workstation screen

    baud_rate

    Any legal baud rate.

    options

    can be any combination of:

    i

    input

    o

    output

    u

    UART

    e

    echo input to output

    ne

    do not echo input

    r

    reset indicated serial port (a and b ports only)

    If either a or b is supplied, and no options are given, the serial port is assigned for both input and output. If k is supplied with no options, it is assigned for input only. If s is supplied with no options, it is assigned for output only.

    v virtual_address1 virtual_address2 [size]

    For example, the following command displays the contents of virtual address space from address 0x1000 to 0x2000 in word format:

    v 1000 2000 W

    w [virtual_address][argument]

    Set the execution vector to a predetermined or default routine. Pass virtual_address and argument to that routine.

    To set up a predetermined routine to jump to, a user program must, prior to executing the monitor's w command, set the variable *romp->v_vector_cmd to be equal to the virtual address of the desired routine. Predetermined routines need not necessarily return control to the monitor.

    The default routine, defined by the monitor, prints the user-supplied vector according to the format supplied in argument. This format can be one of:

    %x
