                     Additional information


This section of the Release Notes describes features of DR DOS 6.0
that are not explained elsewhere in the DR DOS 6.0 documentation.

Microsoft Windows 3.1

    DR DOS 6.0 is fully compatible with Microsoft Windows 3.1.

        The Windows 3.1 default drive for temporary swap files is the drive
        on which Windows was installed. If Windows is installed on a
        SuperStor drive it is recommended that users change the default
        drive for swap files to an uncompressed drive. This should be done
        for both temporary and permanent swap files. Use the 386
        Enhanced option from Control Panel to change swap files.

    If Super PC-Kwik is already loaded when you install Windows 3.1,
    you are informed by the Windows SETUP program that SUPERPCK.EXE
    is running and you are warned that your system may fail; ignore
        this message and continue with the Windows installation procedure.

        Windows 3.1 makes changes to autoexec.bat and config.sys on
        installation. It is recommended that you make a backup of these
        files.

    By default, Windows installs the SMARTDrive disk cache program
    and the HIMEM.SYS memory manager. However, the DR DOS 6.0 disk
    cache, Super PC-Kwik, and the DR DOS 6.0 MemoryMAX drivers provide
    superior functionality over the Windows 3.1 SMARTDrive disk cache
    and HIMEM.SYS. To use Super PC-Kwik and the DR DOS MemoryMAX
    drivers, instead of SMARTDrive and HIMEM.SYS, you simply remove one
    line from your autoexec.bat and config.sys files. Edit autoexec.bat
    to remove the line

    C:\WINDOWS\SMARTDRV.EXE

    and edit config.sys to remove the line

    DEVICE=C:\WINDOWS\HIMEM.SYS

        The above lines should be removed after Windows 3.1 has been
        installed but prior to rebooting.

        If you are using the DR DOS 6.0 EMM386.SYS MemoryMAX driver, Windows
        may also replace the EMM386.SYS line in your config.sys file with
        the Windows EMM386.EXE line. As a result of this change, your system
        may generate an error message when rebooting. The EMM386 line should
        be changed back to its original form after installing Windows 3.1 for
        your system to boot properly. Refer to the backup of your config.sys
        to be sure that you have the correct syntax.

        The Windows 3.1 installation will also insert a STACKS command
        into the CONFIG.SYS. Even though DR DOS does not use a STACKS
        command the line can be left in CONFIG.SYS. No error will
        result.

    DR DOS 6.0 is compatible with both the SMARTDrive disk cache and
    with HIMEM.SYS. If you want to continue using these drivers, you
    must run the DR DOS SETUP program, and remove MemoryMAX and Super
    PC-Kwik. However, if you do use SMARTDrive instead of Super PC-Kwik,
        do not use the SMARTDrive + option to enable caching on a SuperStor
        compressed drive. Unexpected errors may result when this option is
        used.

    EMM386.SYS supports upper memory for Windows 3.1 running in Standard
    or Enhanced mode. You no longer need to use the /WINSTD option on the
        EMM386.SYS command line to run Windows 3.1 in Standard mode.

    NOTE: Machines that have LPT1 ports and are using NE2000 network
    cards configured for I/O address 360 have occasionally hung or had
    trouble running DOS applications under Windows 3.1. If this is
    encountered, try setting the NE2000 for a lower I/O address.


Installation

    System security Master password

    Note that it is very important to keep your Master Key
    password secret, and in a safe place. Once you have chosen
    the secure system option and specified a Master password,
    you will not be able to reinstall DR DOS, or disable the
    security, without the correct password.

    System security and UNINSTAL

    Once you have chosen the secure system option, you cannot
    use the UNINSTAL command to "uninstall" DR DOS and restore
    your old operating system until security is disabled.

    Compressed drives

    Before creating any SuperStor compressed drives, read
    section 13.3 of the DR DOS 6.0 User Guide. This section
    gives important information about the impact of (and
    procedure for) creating a compressed partition.

    It is strongly recommended that you backup all your data
    before converting a drive to a SuperStor compressed drive.
    If you decide to remove the drive later, all the data
    contained on it will be deleted.

    If you are using another operating system, be sure to
    check that it supports compressed drives, before
    creating SuperStor drives; earlier versions of DR DOS (and
    DR MDOS 5.0), for example, do not.

        DISKOPT is a DR DOS 6.0 disk optimization utility which is
        recommended for optimization of a SuperStor drive. DISKOPT is able
        to properly analyze the internal allocation tables of a SuperStor
        drive by letting the SuperStor driver act as interpreter to the
        drive.

        Third party disk utilities may not be able to properly define the
        internal structure of a SuperStor drive. These utilities are NOT
        recommended as their effect on a DR DOS 6.0 SuperStor compressed
        drive are indeterminable.

        Copy protected software or position dependent software should be
        removed before using SuperStor. Copy protected software may be
        reinstalled after the drive has been compressed with SuperStor.

        If DELWATCH is being used DELPURGE should be run to remove pending
        delete files from a drive before using SuperStor.

    Multi-boot utilities

    "Multi-boot" utilities, such as OS/2 DualBoot, typically
    depend on re-writing the boot sector after DOS is
    installed. If you install DR DOS on top of a system
    using a multi-boot utility, the multi-boot may not
    work properly after installation; remove the multi-boot
    utility, install DR DOS, and then reinstall the
    multi-boot utility.

Troubleshooting

    Using AutoCAD R11

    Before running AutoCAD R11, ensure that    Ctrl+Break
    checking is OFF. You can display current Ctrl+Break status
    with the BREAK command, and disable it by typing BREAK OFF.
    You can also disable it by changing the BREAK entry in
    config.sys using the SETUP command.

    Using disk maintenance programs

    Although DR DOS can create and read hard disk partitions of
    up to 2 Gbytes, some older versions of disk maintenance
    programs (for example, Norton Utilities or PCTOOLS) only
    support disk partitions up to 32 Mbytes. When run on larger
    partitions, they will display a "Drive Not Ready" error message.
    Contact your software supplier for a more recent version of
    the disk maintenance program.

        Using Microsoft Windows 3.0 in Real mode

    Note that before you load Windows in Real mode, you should
    ensure that upper memory (and additional memory created by
    the /VIDEO option of EMM386.SYS or HIDOS.SYS) are disabled.
    Upper and Video memory are disabled by default, but you can
    also use the following MEMMAX command if necessary:

        MEMMAX -U -V

    Troubleshooting information

    Refer to the following sections of the DR DOS 6.0 User
    Guide for "troubleshooting" information: Chapter 12, "Using
    MemoryMAX", Chapter 13, "Optimizing your disk", and
    Appendix A, "Error messages and troubleshooting". You can
    also find the same information in DOSBook.

Utilities

    DISKOPT and UNDELETE

    Note that after you use DISKOPT to optimize your disk, you
    can only recover files saved by DELWATCH with UNDELETE.

        SCRIPT

        The SCRIPT utility will now load as a TSR on LPT1.

    FDISK

    The FDISK utility, to partition a hard disk, now has two
    additional options:

    1.    Select the "Re-write master boot record" option if
        the SETUP program cannot install system security
        because of an incompatible existing "master boot
        record". FDISK saves a copy of the existing record
        in a file called c:\oldmbr.bin and writes the standard
        DR DOS master boot record in its place.

    2.    Select the "Restore original master boot record"
        option to restore the original record from
        c:\oldmbr.bin.

    For a full description of the FDISK utility, refer to the
    DR DOS 6.0 User Guide.

    DELWATCH

    Some third-party memory managers may incorrectly report the
    amount of free disk space if they read the FAT directly;
    this is because pending delete files saved when DELWATCH is
    active are not marked as "free" until the space is actually
    required or you delete them using DELPURGE.

    LOCK and Microsoft Windows

    You can use the DR DOS LOCK program, to temporarily lock your
    system, when you are running Microsoft Windows.

    To install LOCK under Windows, do the following:

    1.    Load Windows and select the program group in which
        you want LOCK to appear (the ACCESSORIES group, for
        example).

    2.    Open the Program Manager File menu and select the
        "New" option. Then select "Program Item" in the
        dialogue box and press OK.

    3.    Enter "DRI Lock" in the "Description" field of the
        next dialogue box and "LOCK.EXE" in the "Command Line"
        field. Then press OK.

    4.    The LOCK icon, a red padlock, now appears in the
        program group you selected.

    To use LOCK under Windows, do the following:

    1.    Click twice on the LOCK icon to run LOCK. Press the
        "Lock system" button to lock the system.

    If your system is secure (that is, you have installed system
    security), your computer locks immediately. Enter your existing
    User or Master password to unlock it.

    If your system is not secure, you are prompted for a password
    to lock it.

    Note that if you want to hide the contents of your screen, select
    the "Hide Screen" option. The screen is restored when you enter
    the correct password.

        Super PC-Kwik and Protected Mode Applications

    If you get an "out of memory" error from protected-mode
    applications such as Lotus 1-2-3 R3.1 or AutoCAD R11
    (which use DOS extender technology), make sure that Super
    PC-Kwik is configured with enough reserved memory in SETUP
    or use the /R:nnnn switch with the SUPERPCK command.

    SuperStor

    You can force the entire SuperStor driver, SSTORDRV.SYS, to
    load into conventional memory by using the /NOHI option in the
    DEVICE statement.

    DEVICE = c:\sstordrv.sys /NOHI

    This option is primarily of value when you want to manipulate
    memory configurations for diagnostic purposes.

        CHKDSK and third party utilities will NOT normally portray the
        proper amount of available space on a SuperStor drive. This is
        because CHKDSK and most third party utilities base their free
        amounts on a perfect 2:1 compression ratio. However, free space on a
        SuperStor drive will actually vary due to the differing compression
        ratios of the files stored on a SuperStor drive.

        DIR, XDIR and SSTOR.EXE's statistics option may be used to properly
        determine the current SuperStor free space. All three of these
        options have adjustments built into them to account for the
        differing compression ratios of the files stored on a SuperStor
        drive.

    MemoryMAX (HIDOS.SYS with LIM EMS)

    HIDOS.SYS can now provide upper memory for any machine
    equipped with an Expanded Memory Specification (EMS) memory
    board together with its Expanded Memory Manager (EMM)
    device driver software. Note that expanded memory hardware
    is required; software that provides expanded memory using
    extended memory or disk storage will not work properly.
    HIDOS.SYS can use expanded memory in two ways:

    1.    If your expanded memory hardware/software provides
        mappable upper memory outside the page frame, then
        HIDOS.SYS will automatically detect and use this
        memory and no special HIDOS.SYS command line
        options are required (there is in fact a command
        line option (/CHIPSET=EMSUMB) which tells HIDOS.SYS
        to use mappable upper memory outside the page
        frame). Mappable upper memory outside the page
        frame requires suitable hardware together with
        EMS 4.0 or Enhanced EMS (EEMS) software.

    2.    If your expanded memory hardware/software does not
        provide mappable upper memory outside the page
        frame, or if you do not want to use expanded memory
        for anything other than providing upper memory,
        then you can instruct HIDOS.SYS to use all mappable
        upper memory including the page frame. Since
        HIDOS.SYS will not do this by default, you need to
        specify /CHIPSET=EMSALL on the HIDOS.SYS command
        line. If this option is used, HIDOS.SYS will
        prevent any other programs from using expanded
        memory.

    To let HIDOS.SYS use expanded memory, you must load your
    Expanded Memory Manager software before loading HIDOS.SYS,
    so the DEVICE= line in config.sys for the Expanded Memory
    Manager must be included before the DEVICE=HIDOS.SYS line.
    For example, to use mappable upper memory excluding the
    page frame using an AST RAMpage board using AST's REMM.SYS
    Expanded Memory Manager, put the following in your
    config.sys:
        DEVICE=REMM.SYS
        DEVICE=HIDOS.SYS

    To use all mappable upper memory including the page
    frame:
        DEVICE=REMM.SYS
        DEVICE=HIDOS.SYS /CHIPSET=EMSALL

    If you wish to use the /VIDEO option of HIDOS.SYS so that
    conventional memory can be extended into video memory space,
    then you may need to tell your Expanded Memory Manager to
    provide mappable upper memory in this area. Some Expanded
    Memory Managers will provide this automatically, but some
    will not. Consult the documentation for your expanded
    memory manager software as required. For example, to use
    video memory space using HIDOS.SYS with later versions of
    AST's REMM.SYS Expanded Memory Manager, put the following
    in your config.sys:
        DEVICE=REMM.SYS /L=A000-B7FF
        DEVICE=HIDOS.SYS /VIDEO

    If you do not want HIDOS.SYS to use EMS at all, then either:

        Load HIDOS.SYS before the Expanded Memory Manager.
    or
        Use the HIDOS.SYS /CHIPSET=NONE command line option.

    TaskMAX

    When TaskMAX is unable to switch tasks, it waits for a few
    seconds and then sounds a "beep".

    TaskMAX is unable to switch for one of the following
    reasons:

        There is not enough available swap space.
            Exit your current task or delete some
            unwanted files on the disk.

        You are running an application that changes
        hardware configuration.
            Exit the application.

        You are using Ctrl+P or the COPY command to copy
        files to the printer.
            Wait for printing to finish if the printer
            buffer is full, or turn the printer online,
            if it is not ready.

        You are running an application that talks directly
        to Net BIOS.
            Exit the application.


         Mouse drivers

        All applications should be configured to use
        the Microsoft compatible mouse driver interface
        as supplied with your mouse (mouse.sys or mouse.com,
        for example). Ensure that the mouse driver is loaded
        in config.sys or before TaskMAX in autoexec.bat.

         TASKMAX /F option

        For fastest performance, TaskMAX is configured so
        that user-defined fonts and code page information
        are not retained when you switch tasks.
        Applications that require this function for proper
        screen display may produce garbled results on the
        screen after task switching; should this occur, you
        can use the /F switch with TASKMAX to save the
        fonts when switching. Note that using /F slows down
        switching speed, and causes a slight flashing (on
        some screens) during task switching.

         TASKMAX /M option

        Use the /M option when you load TaskMAX to select a
        specific task using the numeric keys on the main
        keyboard. This option supports keyboards that do not
        have separate numeric keypads.

        You can also edit the taskmax.ini file to
        automatically enable the /M option by default. In
        taskmax.ini, add the following under the subsection
        "[keys]":

        MainNumKeys=1   # 0=use numeric keypad,   1=use main

         TASKMAX /V option

        Use the /V option if any errors occur when
        switching between tasks on a VGA compatible display.
        The /V option forces the VGA to be accessed in the
        same way as an EGA display adaptor.

         Free swap space

        Use the "About TaskMAX..." option on the TaskMAX
        menu to check the amount of free space available.
        Refer to the TaskMAX documentation in Chapter 6 of
        the DR DOS 6.0 User Guide.

         Using communications programs

        Before you use TaskMAX with any communication
        program, configure both the modem and the
        communications program to ignore the status of the
        DTR line; this line would otherwise force the modem
        to break the current telephone connection when the
        communications program switches out.

         Using disk editors

                You CANNOT run applications that access the disk
        directly (disk editors) under TaskMAX when other
        tasks are loaded. You will get errors when the
        disk editor/application tries to write to the
        disk, if you attempt to do so.

    ViewMAX

    When ViewMAX is configured to use an EGA or VGA display,
    it automatically determines the current display type,
    either Monochrome or Color, EGA, or VGA. If, for any reason,
    a different display mode is required, ViewMAX can be forced
    to work with a specified display type by editing the
    VIDPATCH keyword in viewmax.ini (using the DR DOS EDITOR)
    with the following contents:

        VIDPATCH = nn

    where nn is replaced by a digit between 00 and 03.

        00    Monochrome EGA Display
        01    Color EGA Display
        02    Monochrome VGA Display
        03    Color VGA Display

    You can make additional memory available for ViewMAX by
    disabling the clock and calculator accessory. To do this
    rename viewmax.acc to (for example) viewmax.ack. ViewMAX
    will then not attempt to load the accessory. Refer to the
    RENAME command description in the DR DOS 6.0 User Guide.



                          Amended information


    This section of the Release Notes describes features of
    DR DOS 6.0 that are described incorrectly in the
    DR DOS 6.0 User Guide.

    COPY command

    When you specify the /A or /B switch before the first
    wildspec or filespec in the COPY command line, all files
    specified in the command line are treated as ASCII text
    (in the case of /A) or binary (in the case of /B).

    DELPURGE command

    The default for DELPURGE is to prompt before removing
    pending delete files; specify the /A switch to remove
    files without prompting.

    The /S switch includes files in subdirectories below the
    specified subdirectories, but if you also include /L, the
    files in subdirectories are only listed (not removed). For
    example:

        DELPURGE /SL

    MEM command

    The following switches are also available with the MEM
    command:
        /F    Displays memory blocks in segment FFFF
            (high memory).

        /U    Displays memory blocks in upper memory.



                       SuperStor error messages


    You may get the following error messages when using the
    SuperStor program, but they are not included in the
    DR DOS 6.0 User Guide.

Boot files not found while compressing a bootable drive

    Origin        SSTOR
    Explanation    SSTOR was unable to locate the operating
            system files. Use SYS to copy the system
            files to your C: drive.

Cannot create empty bootable partition

    Origin        SSTOR
    Explanation    The C: drive cannot be converted to a
            compressed partition if there is not an
            operating system installed.

Cannot remove current default drive

    Origin        SSTOR
    Explanation    The current default drive cannot be
            removed; switch to another drive and run
            SSTOR again.

Cannot run with Windows or another active task switcher
Cannot run while TASKMAX has other sessions active

    Origin        SSTOR
    Explanation    SSTOR may not be executed while Windows,
            TaskMAX or another multitasking system is
            loaded.

CONFIG.SYS file not found

    Origin        SSTOR
    Explanation    SSTOR requires that there is a config.sys
            file on a bootable drive. If you do not
            have a config.sys file, create an empty
            one using the EDITOR.

Disk structure errors encountered
Run CHKDSK to correct

    Origin        SSTOR
    Explanation    Errors have been encountered in the file
            allocation table on the host drive. Use
            CHKDSK to correct the errors, and run
            SSTOR again.

Error initializing FAT buffer
Error initializing Dir buffer

    Origin        SSTOR
    Explanation    The SSTOR program encountered an error
            while building the memory based copies of
            the file allocation table or the root
            directory structure. This is most likely
            caused by insufficient memory.

Error reading drive parameters IOCTL error

    Origin        SSTOR
    Explanation    SSTOR cannot get the parameters for the
            specified drive, or error on host drive.
            Use CHKDSK to verify the integrity of the
            drive.

Insufficient free disk space to continue

    Origin        SSTOR
    Explanation    When compressing a drive which already
            contains files, there must be approximately
            1.5 Mbytes of free space on the drive for
            a temporary file.

Memory allocation error

    Origin        SSTOR
    Explanation    Insufficient memory to run the SSTOR
            program.

No non-compressed partitions available

    Origin        SSTOR
    Explanation    There are no drives which could be
            compressed, which are not already
            compressed.

No SuperStor disks present

    Origin        SSTOR
    Explanation    No compressed drives are currently
            available.

Specified disk size too large

    Origin        SSTOR
    Explanation    SSTOR cannot create a compressed drive
            larger than 512 Mbytes (a physical drive
            of 256 Mbytes).

SuperStor driver not found
SuperStor device open error

    Origin        SSTOR
    Explanation    The SuperStor driver is not loaded, or is
            not responding. The driver is required by
            the SSTOR program to convert drives which
            already contain files.

System area initialization error

    Origin        SSTOR
    Explanation    An error has been encountered while
            writing the system area of the compressed
            drive to the file.

Drive structure error - mounting read only

    Origin        SSTORDRV.SYS
    Explanation    An error has been detected in the internal
            SuperStor tables. You will not be able to
            write to the drive until this error has
            been corrected. Use CHDKSK to rectify the
            fault.

Host file structure error, not mounted

    Origin        SSTORDRV.SYS
    Explanation    The host file has an allocation or other
            error which stops the driver from loading
            correctly. Use CHKDSK to verify the
            integrity of the host file.

Incompatible DOS version

    Origin        SSTORDRV.SYS
    Explanation    The SuperStor driver cannot be used with
            the version of DR DOS or DR MDOS which you
            are running.

Invalid fragment maximum. Space for 128 reserved

    Origin        SSTORDRV.SYS
    Explanation    The host file contains too many
            non-contiguous blocks. The maximum number
            of allowable fragments is 128. To correct the
            problem, enter the following sequence of
            commands (where "x" is the drive):

            ATTRIB -HS  x:\SSPARTSS.*

            DISKOPT x:

            ATTRIB +hs  x:\SSPARTSS.*

            Then reboot your system.
