DESCRIPTION
       Disk Operating System Version 4.00 is compatible with
DOS 3.30, which will continue to be marketed, and supports all IBM
Personal System/2s and IBM personal computers, except PCjr, AT/370,
and XT/370.  An upgrade to DOS Version 4.00 from all prior levels of
DOS is being offered at a reduced charge.
       Details of the new DOS Version 4.00 function are as follows:
o   Large nonpartitioned DASD support is provided.  The new
    addressing format of 32-bit versus 16-bit removes the limitation
    of 32Mb DASD partitions.  For compatibility, DOS Version 4.00
    retains the ability to install on and use currently formatted
    fixed disks.  After DOS Version 4.00 is installed with >32Mb
    partitions, the user cannot boot from DOS 3.30 and read the files
    on the fixed disk.  Some applications may be incompatible with
    SHARE.  SHARE is automatically installed if the user has >32Mb
    partitions.
o   A DOS shell is provided as an alternative to the DOS prompt to
    increase useability.  The DOS shell has a similar appearance to
    the OS/2 (TM) Presentation Manager.  It provides facilities and
    utilities for the range of day-to-day tasks.  It is possible to
    start up and use applications when necessary; to access
    information and data in the file systems; to obtain hard copy
    output; and to get Help information relevant to the task.  These
    actions are accomplished by straightforward selections from
    menus, using either a mouse or the keyboard.  The shell will run
    in either text or graphics mode.  Installation of the DOS shell
    is optional.
 (TM) Trademark of the International Business Machines Corporation.
o   Disk Operating System Version 4.00 provides support for the
    Lotus/Intel/Microsoft (LIM) Expanded Memory Specification
    Version 4.0.  Expanded memory is addressed through a combination
    of an EMS device driver and an IBM hardware adapter capable of
    expanded memory.  This memory enhancement is available if one of
    the following is installed:
    -   Planar memory installed above 1Mb on a PS/2 Model 70 or 80
        (can be used as EMS memory)
    -   IBM 2Mb Expanded Memory Adapter
    -   IBM Personal System/2 80286 Expanded Memory Adapter/A
    -   IBM Personal System/2 0-8Mb Expanded Memory Adapter/A
    -   IBM Personal System/2 80286 Memory Expansion Option or
        software emulated XMA using the 80386 paging capabilities on
        Personal System/2
    -   IBM Personal System/2 80386 Memory Expansion Option
    -   IBM Personal System/2 2-8Mb 80386 Memory Expansion Option.
           DOS 4.00 uses expanded memory for DOS 4.00 functions for
    the DOS 4.00 BUFFERS, FASTOPEN, and VDISK functions to conserve
    storage.
           EMS memory can be used only by application programs that
    comply with the EMS specification.
o   A full-screen installation utility, SELECT, is provided to
    simplify the installation of DOS 4.00.  SELECT allows easy
    selection of all parameters required to install DOS 4.00,
    including selection of country and code page support.
    AUTOEXEC.BAT and CONFIG.SYS files are automatically generated by
    the install process.  If preconfigured defaults are accepted, a
    national user has selected automatically the appropriate national
    keyboard, country information, date/time format, and code pages.
    Only if the user needs to select different country information
    will the full-screen utility be needed to bypass the defaults.
o   Video and graphics support:
    -   DOS 4.00 provides support for a text mode (versus graphics)
        Command Line display interface when not using the shell.
    -   DOS 4.00 supports greater than 25 lines of text on Enhanced
        Graphics Adapter (EGA) and Video Graphics Array (VGA)
        displays with the appropriate capability.
    -   GRAFTABL is extended to support the multilingual code page
        850.
    -   GRAPHICS has been extended to support the graphics display
        modes of the EGA, VGA, IBM Personal System/2 Display Adapter,
        and IBM Personal System/2 Display Adapter 8514/A.  This
        provides graphic print screen support for the IBM Graphics
        Printer, IBM Proprinter (TM), IBM Color Printer, IBM PC
        Convertible Printer, or any other IBM personal computer
        printer with compatible graphic print modes.
    -   DOS 4.00 uses a printer profile file (GRAPHICS.PRO) that
        describes characteristics of different printers users can
        modify for other IBM personal computer printers.  This is
        used in conjunction with graphics.
     (TM) Trademark of the International Business Machines
       Corporation.
           Other enhanced DOS Version 4.00 functions are as follows:
    -   ANSI.SYS has a new /x parameter enabling extended keyboard
        reassignments and a new /l parameter that will try to enforce
        the number of lines set through MODE command -- even within
        an application.
    -   APPEND has been enhanced to allow more control of its
        searching operations.
    -   BACKUP automatically formats the target diskette if the
        diskette is not already formatted.
    -   BUFFERS has new parameters to improve DOS buffer cache
        support and to utilize buffers in EMS.
    -   CHKDSK displays volume serial number, if found, and the
        allocation units in the status report.
    -   COUNTRY provides support for the additional countries Japan,
        Korea, Peoples Republic of China, and Taiwan.
    -   DEBUG now provides EMS support.  Detailed information is
        contained in the DOS Version 4.00 Technical Reference
        Application Programming product, available separately.
    -   DISPLAY.SYS checks the hardware to select the type of active
        display, if the display adapter type is omitted.
    -   ERASE or DEL has a new /p parameter that displays each
        filename and a message to verify that the file is to be
        deleted.
    -   FASTOPEN has a new /x parameter that allows FASTOPEN to
        perform its function by using expanded memory, saving space
        in low memory for application programs.  FASTOPEN now stores
        file information in memory to allow faster retrieval of
        recently opened files.
    -   FDISK now uses 80 display columns, accepts disk partition
        sizes in megabytes or percentages, and displays the volume
        label and file system for each partition.
    -   FORMAT accepts a new /f size parameter.  This indicates the
        size of the diskette to format, making it easier to format

        media less than the maximum capacity of a drive.
    -   KEYB has a new parameter that selects a specific keyboard
        layout where countries (such as France, Italy, and the United
        Kingdom) offer multiple enhanced keyboards.
    -   MEM is a new program that displays the memory configuration
        of the system.  The /debug or /program switches give a
        detailed description of the memory usage.
    -   MODE is enhanced to allow selection of keyboard typematic
        rates and lines per screen.
    -   PRINTER.SYS now provides near letter quality font support for
        the Proprinter.
    -   REM is an enhanced command to allow comments or line spacing
        in a batch or CONFIG.SYS file.
    -   REPLACE has a new /U parameter.  It restricts REPLACE to only
        update files with a date and time on the source diskette more
        recent than the date and time on the target diskette.
    -   SYS moves the first two entries in the root directory to
        place IBM BIOS and IBM DOS as required, if the format /s
        command was not performed.
    -   TREE displays block graphics and indent at each subdirectory
        level.
    -   VDISK /x: is provided to use expanded memory using XMA2EMS.
       The Disk Operating System Version 4.00 product includes the
BASIC Interpreter Program Version 4.00.  The existing BASIC
Reference, Version 3.30 (6280189) manual describes BASIC 4.00 and is
available separately.
       The DOS 4.00 library has been redesigned to improve useability
and to support new program functions.  Getting Started with Disk
Operating System Version 4.00 assists with the installation process
and provides a tutorial on the new DOS Version 4.00 shell.  Using
Disk Operating System Version 4.00 describes how to use DOS 4.00 to
complete daily tasks and routines.  World Trade keyboard information
is contained in IBM Keyboard Layouts For Your PC and PS/2 (R) and is
available free of charge by mailing the postcard included in the
DOS 4.00 package.
       The new Disk Operating System Version 4.00 Technical Reference
Application Programming product, separately available, has been
reorganized and provides reference and system architecture
information in a task-oriented manner for the experienced user,
system programmer, and application developer.  It is assumed that the
user is familiar with the 8088/8086, 80286, or 80386 microprocessor
architecture.  This new product has been updated with DOS 4.00
related topics.  As with DOS 3.30, the Disk Operating System
Version 4.00 Technical Reference Application Programming product
contains the DEBUG, LINK, EXE2BIN, VDISK.ASM, and LIB programs.
       A new Disk Operating System Version 4.00 Command Reference
manual is also available as a separate item and contains detailed
DOS command information for advanced DOS 4.00 users.

MEMORY REQUIREMENTS:  256KB is the minimum memory requirement for
DOS 4.00 systems.
PROGRAMMING REQUIREMENTS:  To use the 'hot key' operations required
by host communication emulators (such as 3270 emulators), certain
restrictions apply if the shell is run in graphics mode.  To operate
without restrictions, it is recommended that the shell be operated in
text mode.  For further information on the restrictions and how to
run the shell in text mode, see Chapter 5, 'Text or Graphics Mode' of
the Getting Started with Disk Operating System Version 4.00
publication.
COMPATIBILITY:  DOS 4.00 is an upwardly compatible enhancement to
DOS Version 3.30 and contains maintenance updates.  DOS 4.00 supports
all members of the IBM Personal System/2 and Personal Computer
families (except PCjr, AT/370 and XT/370).  DOS 4.00 maintains
compatibility with most applications that operate on DOS 3.30.  These
programs will function substantially as described in program
literature if the DOS 4.00 and BIOS protocols and conventions are
observed and no timing dependencies in the application code exist.
This information is in the Disk Operating System Version 4.00
Technical Reference Application Programming product.
       Care should be taken when using utilities or tools that write
directly to the hardware, for example, utilities or programs that do
not use DOS calls.  Use of a disk repair utility that was compatible
with DOS 3.30 may not be compatible with the DOS 4.00 file structure
and could cause loss of all data on a fixed disk.
       The storage required by DOS 4.00 is greater than previous
versions of DOS.  Some programs may not fit in the same size machine.
       DOS 4.00 is supported by IBM PC Local Area Network Program
Version 1.3.

INSTALLABILITY:  Instructions for installing DOS 4.00 are in the
Getting Started with Disk Operating System Version 4.00  publication.
If the DOS 4.00 start up diskette is present in diskette drive A, or
if DOS 4.00 is properly configured on the appropriate fixed disk,
DOS 4.00 is automatically loaded in memory when the system is started
or restarted.  If automatic program execution is not used each time
DOS 4.00 is initialized, the user is asked for the current date and
time (on systems with a CMOS clock, the current date and time is
displayed).  This information is used to identify the most recent
update to a file.  If the AUTOEXEC option is used and unattended
operation is desired, date and time prompting can be bypassed.
