GENERAL SYSTEM CONSIDERATIONS

   o   This updated version of OS/2 2.1 includes
       additional APM support that was not available
       for the original OS/2 2.1 release.  Laptops
       not previously supported might now have APM
       support.

   o   OS/2 2.1 uses a system proportional font
       that is designed to meet the International
       Standards Organization (ISO) 9241 standard
       and the German DIN 66234 standard on
       suitable hardware.

       ISO compliant fonts cause some text strings
       to be clipped.  If you do not want to use
       ISO compliant fonts, modify the OS2.INI
       file to install fonts that are not ISO
       compliant.  Font changes made in the
       OS2.INI file are global across all
       applications.  If you have REXX installed,
       you can type the following information into
       a CMD file and use it to change the font.

           /* */
           call RxFuncAdd "SysIni", "RexxUtil", "SysIni"
           AppName = "PM_SystemFonts"
           KeyName = "DefaultFont"
           FontName = "10.System Proportional Non-ISO"
           call SysIni "USER", AppName, KeyName, FontName||"0"x
           exit

       After the file has been run, shutdown and
       restart the system.
   o   If you experience video corruption:
       -   Display the pop-up menu for the
           desktop; then select Refresh to redraw
           the desktop.
       -   If the screen goes blank, press Alt+Esc
           to switch between the applications to
           force repainting of the screen.


   o   DOS Images on the hard disk (VMBs) need to
       use the FSFILTER and FSACCESS drivers
       provided with this version of OS/2.
       FSFILTER and FSACESS drivers are located in
       the \OS2\MDOS directory.
   o   The Check disk option for a CD-ROM object
       will not display information about the
       CD-ROM.  To obtain information about the
       CD-ROM:
       1.  Point to the CD-ROM drive object.
       2.  Click mouse button 2.
       3.  Select the arrow to the right of Open.
       4.  Select Details view.
   o   During a system shutdown, there might be
       times when the "Shutdown is completed"
       message is not displayed.  If this happens,
       wait until all disk activity is complete,
       then power off the system.
   o   If you are installing OS/2 2.1 over a
       system that has OS/2 2.0 installed, the
       desktop directory name will be "OS!2_2.0_D"
       and the title of the desktop will be "OS/2
       2.0 Desktop".  On a system that has OS/2
       2.1 installed, the desktop directory name
       will be "Desktop".

   o   If you have a preinstalled system, and you
       change your country or keyboard configuration
       using the Configure Preinstalled System program,
       located in the Configuration Tools folder, the
       changes only occur for OS/2 sessions.
       To configure the country and keyboard for WIN-OS/2
       sessions, use the International icon from the
       WIN-OS/2 Control Panel.

   o   After installing OS/2 2.1 on your system, use the
       Migrate Applications program to migrate your programs
       instead of the Selective Install program.  The
       Migrate Applications program is located in the System
       Setup folder.

   o   If you are running CHKDSK from the command line
       without the /F parameter on an HPFS partition which also
       contains your SWAPPER.DAT file, you may receive a SYS0552
       error message. This message can be ignored. If you are using
       CHKDSK from the popup menu of a drive icon, you may receive a
       WARNING message stating "The disk is in use or locked by
       another process." If this occurs, CHKDSK will not let you
       display the graphical representation of disk usage.

WIN-OS/2 APPLICATION COMPATIBILITY

   o   The original WIN-OS/2 color scheme was added
       to the list of available color schemes in
       the WIN-OS/2 color panel.  If you change color
       schemes and would like to return to the original
       color scheme, select WIN-OS/2 Original.
   o   The performance of Windows programs that
       use floating point operations can be
       improved by changing the WIN-OS/2* setting,
       WIN_RUN_MODE, to Enhanced Compatibility.
   o   Windows scanning programs should be run in
       a WIN-OS/2 full-screen session to avoid
       video corruption.
   o   To ensure the integrity of 16-color bit
       maps on SVGA, XGA, and 8514 systems, run
       Microsoft Paint Brush in a WIN-OS/2
       full-screen session.
   o   Some messages encountered in a WIN-OS/2
       window session request that you select
       either Ignore or Close, however the only
       options are Ignore and OK.  Select OK
       instead of Close.
   o   If you are using a WIN-OS/2 window session,
       an OS/2 Presentation Manager session, and a
       DOS full-screen session, Alt+Esc might not
       sequence through all of the windows
       correctly.  Alt+Esc might switch to the
       WIN-OS/2 session every other time or the
       DOS full-screen session might never be
       displayed.

       To avoid this problem, press Ctrl+Esc or
       press mouse buttons 1 and 2 at the same
       time to display the Window List then select
       the desired session.
   o   If you are in a full-screen WIN-OS/2
       session and you encounter a problem where
       transparent desktop icons appear over open
       windows, minimize or maximize the window to
       force repainting.
   o   The Copy Disk option for the WIN-OS/2 File
       Manager does not prompt for a target
       diskette.  Use the DISKCOPY command in
       either a DOS or OS/2 command prompt session
       instead.
   o   During installation of the Windows 3.1 SDK,
       a message is displayed stating that the
       installation program cannot find
       KRNL286.EXE or KRNL386.EXE.  Ignore the
       message and continue installation.  The SDK
       will function normally.
   o   If you are using the Winsleuth Gold
       hardware diagnostics program:
       -   Do not run Chip test (RAM test
           program).  Chip test attempts to lock
           hardware interrupts.  OS/2 2.1 does not
           allow programs to lock hardware
           interrupts.
       -   When the video mode hardware test
           switches from character to graphics
           mode, a "suspended" message might
           appear.  If the message appears, Select
           Full-screen from the Sessions System
           menu.  Testing will resume.

    ------------------
    Run in a WIN-OS/2 full-screen standard-mode session.


    Paint Brush**
    -------------
    To ensure the integrity of 16-color bit maps on
    SVGA, XGA, and 8514 systems, run Paint Brush in
    a WIN-OS/2 full-screen session.

    If you are using the Paint Brush program in a
    WIN-OS/2 window session, the mouse pointer/hourglass
    will not disappear when the Zoom In option is
    selected from the View menu.  In a full-screen
    WIN-OS/2 session, the mouse pointer/hourglass
    will disappear and only the Zoom In box will
    remain on the screen.

    If you are using Paint Brush to paint single
    pixels in zoom-in mode, the pixel will look
    unpainted where the mouse pointer covers the
    pixel being painted.  Zoom out and in again to
    see the entire pixel painted correctly.


    Powerpoint** 3.0
    ----------------
    If you are displaying the DROPBXV.PPT and
    GRIDWRVK.PPT demo slides in 640x480x256, you
    might see small horizontal line corruption.

    If you are using a WIN-OS/2 window, you might
    get incorrect background color when viewing a
    thumbnail of a template.  This will not affect
    the running of the application.


    Video for Windows
    -----------------
    Run is a full-screen session.

    If you configure video animation to run full-screen
    in Video playback, Deselect Skip video frames if
    behind, to eliminate any corruption of the video
    during play.


    WindowWorks**
    -------------
    Install in a WIN-OS/2 full-screen session.


    Lotus Improv 2.0 for Windows
    ----------------------------
    Must be installed with WIN-OS/2 running in
    enhance mode, to install and configure
    correctly.



DOS APPLICATION COMPATIBILITY

   o   Use OS/2 system utilities.  DOS system
       utilities might not recognize the extended
       attributes associated with a file.
   o   OS/2 provides integral disk caching and
       memory optimization functions.  Use of the
       equivalent functions that are provided with
       MS-DOS 6.0 is not necessary and may produce
       errors.

APPLICATION NOTES:

    DOS Games
    ---------
    For performance reasons, play in a DOS
    full-screen session.  Change the DOS setting,
    VIDEO_8514A_XGA_IOTRAP to OFF.

    Intel** SatisFAXtion**
    ----------------------
    Must be run in a specific DOS session, unless
    you do the following before you install the program:

    1.  Make a copy of your AUTOEXEC.BAT file and
        name it AUTOEXEC.FAX.
    2.  Install the program.
    3.  Rename the AUTOEXEC.BAT file FAX.BAT.
    4.  Rename the AUTOEXEC.FAX file AUTOEXEC.BAT.
    5.  Make a program object for the SatisFAXtion
        program.
    6.  Change the value of the DOS_AUTOEXEC
        setting for the object to FAX.BAT.
    7.  Save and exit the Settings notebook.


    Microsoft** C/C++ 7.0 Linker
    --------------------------
    If you are using Microsoft C/C++ 7.0 Linker, set

OS/2 APPLICATION COMPATIBILITY

   o   Closing OS/2 applications that use the
       hardware palette (typically picture viewers
       or sample graphic applications)
       occasionally causes a repaint problem on
       the desktop.  If the windows do not repaint
       correctly, a refresh will restore the
       desktop, but any windows that are opened or
       moved will still have the problem.
       Restarting the system is the only way to
       completely correct this problem.
   o   If you are using Lotus 123G for OS/2 or Lotus
       Freelance Graphics for OS/2, you need to run
       the following utility prior to using these
       products with OS/2 2.1.
       1.  Change to the appropriate Lotus
           directory that contains the application.
           For example, type

             CD \123G

       2.  Backup the LD2CORE.DLL file.  For
           example, type

             COPY LD2CORE.DLL LD2CORE.BAK

       3.  Run the update program.  Type,

             LD2FIX

       The Lotus program is now updated.  You need to
       shutdown and restart your system for these changes
       to take effect.


APPLICATION NOTES:

     Communication Manager/2
     -----------------------
     When used with Host Graphics support (HGINST)
     you might experience shutdown problems.
     Ensure that the following GDDM fixes have been
     applied to the host system:

       UN36882 - MVS
       UN38883 - VM/SP
       UN38884 - VM/XA SP
       UN38885 - DOS/VSE


    Netview DM/2 (NVDM/2)
    ---------------------
    If you are using the CID method of
    installation, you will need an updated version
    of the LAPSCID.DLL file.  This file is
    available as LAPDLL.ZIP on the CompuServe
    OS2SUPPORT forum, Lib #17 and the OS2BBS
    on TALKLINK.


    IBM LAN Server 2.0 and 3.0 Remote Installation
    Program Load (RIPL)
    ----------------------------------------------
    An updated version is needed to run with OS/2 2.1.
    The diskette image is available as 2IRIPL.ZIP
    on the CompuServe OS2SUPPORT forum, Lib #17 and
    the OS2BBS on TALKLINK.


    WordPerfect** 5.0 for OS/2
    --------------------------
    If you are using SVGA hardware, you must run
    this application in VGA mode.


DOS AND WIN-OS/2 MULTIMEDIA APPLICATION COMPATIBILITY

   o   The following WIN-OS/2 and DOS Settings
       should be used for Multimedia applications:

            DOS/WIN     INT_DURING_IO               ON
            DOS/WIN     HW_TIMER                    ON
            WIN         VIDEO_SWITCH_NOTIFICATION   ON
            WIN         VIDEO_8514A_XGA_IOTRAP      OFF
            DOS/WIN     VIDEO_RETRACE_EMULATION     OFF


APPLICATIONS NOTES:

    Action!** 2.0
    -------------

    Run in a WIN-OS/2 full-screen session.  Add the
    following line to the AUTOEXEC.BAT file:

       SET TEMP=C:\


    Animation Works** 1.0
    ---------------------
    Run in 640x480 resolution.


    IconAuthor** 4.0
    ----------------
    If you are running the demo for this program,
    you must exit and reenter the WIN-OS/2 session
    before running the actual application.


    Linkway** Live 1.0 (Tool Series)
    --------------------------------
    Use the following DOS setting to make the demo
    run properly:

      DOS_RMSIZE=576


    MIDI

    Make sure that the MIDI mapper (in the Control
    Panel) is properly set to the sound adapter.


    Nautilus** 1.6 and 1.76
    -----------------------
    Run in a WIN-OS/2 full-screen session.



NETWORK

   o   The Workplace Shell login is not compatible
       with NetWare** 4.0 Directory Services and
       should be disabled unless you are using the
       NetWare 4.0 Bindery Compatibility mode.  To
       disable the login:
       1.  Edit the CONFIG.SYS file.
       2.  Remove the CONNECTIONS option from SET
           AUTOSTART.
       3.  Save and exit the CONFIG.SYS file.
       4.  Restart the system to activate the
           changes.
   o   If you are using the NetWare Requester
       version 2.01, (ships with NetWare 4.0) but
       have no NetWare 4.0 servers, you can
       increase the speed of the login process by
       turning the Directory Services off.  To
       turn the services off:
       1.  Edit NET.CFG file in the root directory
           of the boot drive.
       2.  Add Directory Services Off to the file.
       3.  Save and exit the file.
   o   Novell** NetWare Requester 2.0 and 2.01
       programs NMPIPE.SYS, NPSERVER.SYS, and
       NPDAEMON.EXE require the following
       information to be added to the OS2VER file.
       To add this information to the file:
       1.  At an OS/2 command prompt, type: ATTRIB
           -h -r -s OS2VER
       2.  Edit the OS2VER file in the root
           directory of the boot drive.
       3.  Type the following information in the
           file:

               20=NMPIPE.SYS
               20=NPSERVER.SYS
               20=NPDAEMON.EXE

       4.  Save and exit the file.
       5.  Type ATTRIB +h +r +s OS2VER
   o   If you are using FFST/2 (for example, if
       you enable the FFST/2 feature when
       installing Communications Manager/2 or Data
       Base Manager/2), REM out the
       "RUN=...\EPW.EXE" statement in your
       CONFIG.SYS file.  To utilize FFST/2
       technology, add a "DETACH EPW.EXE" as the
       first statement in your STARTUP.CMD file.


ADVANCED POWER MANAGEMENT

       The OS/2 2.1 APM support relies on the
       power status information returned from the
       BIOS on your laptop.  You might notice
       incorrect battery life or status within the
       power icon on your laptop.  If this occurs,
       rely on the LEDs on your laptop for
       accurate power status information.
   o   Turning the APM setting to OFF also turns
       off the BIOS power management.  If you want
       to turn off the APM but not the BIOS power
       management, place REM before the APM device
       driver statement in your CONFIG.SYS file,
       then restart your system to invoke the
       change.

         REM DEVICE=C:\OS2\APM.SYS


DISPLAY ADAPTERS (IMAGE, SVGA, XGA, 8514)

   o   The OS/2 operating system will experience
       video problems similar to those observed in
       a DOS environment.  These problems are due
       to the failure of a BIOS video mode set.
       An example of this problem is the video
       image on an ALR** Modular PS with a
       Flexview** 2x SVGA display fails to occupy
       the entire screen in 1024 x 768 mode.
   o   If you are using an LCD display and have
       difficulty locating the mouse pointer on
       the screen, you can increase the size of
       the pointer if you are using 640x480
       resolution.  To change the size of the
       pointer (if you have REXX installed):
       1.  Use an editor to create a file called
           LARGE.CMD.
       2.  Add the following information to the
           file.

             /* LARGE.CMD Set VGA pointers to large */
             /* (c) Copyright IBM Corp. 1992, All rights reserved */
             call RxFuncAdd "SysIni", "RexxUtil", "SysIni"
             call SysIni "USER", "PM_IBMVGA", "CURSOR_SIZE", "1",
             say Result
             exit

       3.  Save and exit the file.
       4.  At an OS/2 command prompt, type "LARGE"
           and press Enter.

       This program will increase the size of the
       cursor.  To force a standard size pointer,
       replace the "1" in the program with a "2".
       To let the system select the size of the
       pointer, replace the "1" in the program
       with a "0".
   o   Users of the NCR** Safari notebook, SSL/25,
       should modify the following information in
       the CONFIG.SYS file on their startup drive
       to allow video register shadowing to be
       processed correctly in OS/2 2.1:

           DEVICE=C:\OS2\MDOS\VVGA.SYS
         to
           DEVICE=C:\OS2\MDOS\VSVGA.SYS

   o   Systems with Image Adapters running in
       dual-display modes will lose DOS window
       support after a DOS full-screen or OS/2
       full-screen session has been invoked.  The
       system must be restarted to reinstate the
       DOS window environment.  The problem can be
       avoided by turning off the dual display
       mode under the Image Adapter setup.


SVGA CONSIDERATIONS

   o   The Western Digital** 90C31 SVGA chipset
       will have video problems when Windows 2.x
       applications are run.
   o   If you are using a ZEOS** system with
       Speedstar** VGA, you must run the VMODE
       utility supplied with the system to
       configure the display during the display
       driver installation.
   o   Zenith Data Systems** with Headland HT208
       do not support high resolution modes even
       though you can successfully set these modes
       and install high resolution drivers.  If a
       high resolution mode is used, a white
       half-screen will be displayed.  To correct
       this problem, use DSPINSTL to install VGA.
   o   If you have a Sigma Legend** display
       adapter you might experience minor video
       corruption on the desktop when you switch
       between the desktop and DOS if they are
       running in different modes.  This can be
       corrected by using a DOS utility to set the
       DOS session to the same mode as the
       desktop.


XGA CONSIDERATIONS

   o   If an XGA-2 adapter is installed, and you
       have modified the default display type in
       the System Settings notebook (page 2),
       after you restart the system it will
       display the Workplace Shell* in one
       resolution and WIN-OS/2 in a different
       resolution.  To change the resolution for
       the Workplace Shell:
       1.  Open OS/2 System.
       2.  Open System Setup.
       3.  Open System.
       4.  Select a 640x480xn  resolution.
       5.  Shutdown and restart the system.
       6.  Repeat steps 1 through 3.
       7.  Select the desired resolution.
       8.  Shutdown and restart the system.

       The Workplace Shell and WIN-OS/2 will now
       display in the same resolution.
   o   If you are using a dual display system with
       XGA as the primary display and VGA as the
       secondary display, you might see some minor
       corruption when the XGA display is set to a
       resolution with 65536 colors.  This
       corruption will be on the display that does
       not have focus and will not interfere with
       the operation of the system.
   o   On dual display configurations with XGA-2
       as the primary display and VGA as the
       secondary display, the DOS full-screen
       session might be corrupted if a Windows**
       application is started in a window session.
       To recover from this situation, shutdown
       and restart the system.
   o   If you are using Dual Boot with an XGA-2
       adapter, you must modify the CONFIG.DOS
       file:
       1.  Edit the \OS2\SYSTEM\CONFIG.DOS file.
       2.  Locate the line
           DEVICE=C:\DOS\EMM386.EXE RAM 2048
           X=nnnn-nnnn
       3.  Change nnnn-nnnn to C000-CFFF.
       4.  Save and exit the file.
   o   On IBM P75 systems, there might be some
       corruption on the screen whenever several
       icons are selected and moved together.
       This corruption can be eliminated by
       clicking mouse button 2 to bring up the
       pop-up menu; then selecting Sort.
   o   An IBM P75 system with an external monitor
       attached might only have the 640x480x16
       resolution selection on the the System
       Settings Screen page.  If the external
       monitor is capable of displaying higher
       resolutions, use the P75 reference diskette
       to disable the built-in plasma display.
   o   If you are using an XGA system, the hash
       lines around the icons of open applications
       might change color unexpectedly.  This does
       not interfere with the operation of the
       system.
   o   If you are using an XGA system, extra lines
       might appear on the face of the OS/2 System
       Clock between the quarter (:15) and half
       (:30) hour.  These lines do not interfere
       with the operation of the clock.


8514 CONSIDERATIONS

   o   If you are using the 1MB version of an
       ATI** Graphics Ultra** Pro adapter, the VGA
       memory must be set to SHARED to work
       properly with the OS/2 8514 display driver.
       This might cause some DOS applications
       running in the background to corrupt the
       desktop.  To correct this problem, you must
       upgrade to the 2MB version of the Graphics
       Ultra Pro and set the VGA memory to 256K or
       greater.

       NOTE:  In the "OS/2 Installation Guide", it
       states that the ATI Graphics Ultra Pro must
       be configured to IBM DEFAULT for the
       640x480 display type.  This setting might
       be referred to as 60Hz rather than IBM
       DEFAULT.
   o   If you are using a system with an 8514
       adapter with Windows applications running
       in a WIN-OS/2 window session in separate
       VDMs, video corruption might occur in
       bitmaps when clipping between applications.
   o   After you start a WIN-OS/2 window session,
       256 color bitmaps might become discolored
       due to the sharing of the 256 color
       palette.  This should not affect the
       running of the applications.
   o   Selecting windows in Mathematica might not
       bring focus to the proper window.


AUDIO ADAPTERS

   Audio support in WIN-OS/2 and DOS sessions is
   dependent on installed drivers.  You should
   install the audio adapter driver that came with
   your audio adapter.  When installing audio
   support for WIN-OS/2, be sure to install both
   DOS and Windows device drivers.  Configure
   both drivers to use the same interrupt level and
   DMA channel.

   o   The following drivers are available with
       the Audio Capture and Playback Adapter*
       (ACPA):
       -   ACPADD.SYS
       -   ACPADD2.SYS
       -   ACPAK12.SYS
       -   ACPA.DRV
       The latest updates are available on the IBM
       Bulletin Board Service.
   o   MMPM/2 installs ACPA support for OS/2 only,
       not WIN-OS/2 or DOS.

       There are two ways to get DOS ACPA support
       in DOS sessions:
       1.  Edit the CONFIG.SYS file.
       2.  Add DEVICE=C:\ACPAK12.SYS
       3.  Save and exit the CONFIG.SYS file.
       4.  Copy the ACPAK12.SYS file to the C:\
           directory.
       5.  Restart the system to activate the
           changes.

       Or
       1.  Point to the DOS full-screen or window
           object.
       2.  Click mouse button 2.
       3.  Select the arrow to the right of Open.
       4.  Select Settings.
       5.  Select the Session tab.
       6.  Select DOS Settings.
       7.  Select DOS_DEVICE.
       8.  Type C:\ACPAK12.SYS in the Value field.
       9.  Select Save.
       10. Double-click on the title-bar icon to
           close the notebook.
       11. Copy the ACPAK12.SYS file to the C:\
           directory.

       To install WIN-OS/2 ACPA support:
       1.  Access the Control Panel in WIN-OS/2
           Main.
       2.  Select Drivers.
       3.  Select Add.
       4.  Select Unlisted or Updated Drivers.
       5.  Select OK.
       6.  Insert the diskette containing the ACPA
           driver into drive A.
       7.  Type A:
       8.  Select OK.
       9.  When the next menu level appears,
           select the M-Audio sound driver.
   o   MMPM/2 installs Sound Blaster** support for
       OS/2 only, not WIN-OS/2 or DOS.
   o   To add WIN-OS/2 Sound Blaster support:
       1.  Install the DOS device driver following
           the instructions that came with the
           adapter.  Use an OS/2 DOS session for
           the install.
       2.  Install the Windows driver.

           NOTE:  Be sure to use the same I/O
           address, interrupt, and DMA settings
           used during install of the DOS drivers.

PRINTERS

   o   If you are using the HP** LaserJet**
       printer driver, some complex images might
       not print correctly when LaserJet
       performance options are enabled. If you
       experience incorrect output or degraded
       printer performance, return the performance
       options to the disabled state.  To change
       the performance options:
       1.  Point to the printer object.
       2.  Click mouse button 2.
       3.  Select the arrow to the right of Open.
       4.  Select Settings.
       5.  Select the Printer Drivers tab.
       6.  Select Job properties.
       7.  Change the performance options to their
           default settings.
       8.  Double-click on the title-bar icon to
           close the notebook.
   o   If you experience problems while
       printing bitmaps from an application
       while using the PostScript printer
       driver, Select the Printer-specific
       format option on the Queue options page
       in the Settings notebook of your
       printer object.
   o   The OS/2 printer drivers on the OS/2 2.1
       printer driver diskettes are stored in a
       packed format that is not compatible with
       OS/2 1.3 or 2.0.  To install one of the
       OS/2 2.1 printer drivers on a system with
       OS/2 1.3 or 2.0 installed, you must first
       unpack the driver on a system that has OS/2
       2.1 installed.  You do not have to complete
       these steps to install a printer driver on
       a system that already has OS/2 2.1
       installed.

       NOTE:  Do not install the new 32-bit
       PostScript driver (PSCRIPT.DR_) that came
       with OS/2 2.1 on a system with OS/2 1.3 or
       2.0 installed.  It is not compatible with
       these versions of OS/2.  While testing is
       continuing, current compatibility
       information about tested systems is
       available through your dealer, Marketing
       Representative, CompuServe, IBM National
       Support Center Bulletin Board System (NSC
       BBS), and IBMLink.

       To unpack a printer driver for use on a
       OS/2 1.3 or OS/2 2.0 system, complete the
       following steps on your system that has
       OS/2 2.1 installed.
       1.  Open an OS/2 command prompt.
       2.  Type:

             MD X:\DRIVER

           Where X is a drive on your system.
       3.  Insert into drive A the OS/2 2.1
           printer driver diskette that contains
           the printer driver you want to install.
           The printer driver names end in a "_".

             Printer Driver:  Diskette #   Packed Name:
