MAINTAINS INTERFACES (COMPATIBILITY):  PC DOS Version 6.1 continues
to provide an open system architecture that can be expanded via
system extensions, device drivers and future enhancements.  It also
continues to allow applications to use DOS extensions.  Application
interfaces have been maintained and tested.
PROVIDES EASY UPGRADE:  PC DOS Version 6.1 provides full PC DOS
function with installation specific programs that allow and aid
previous IBM and compatible DOS users to upgrade to PC DOS
Version 6.1 at a significantly lower price.  A prior version of IBM
or compatible DOS (Version 2.1, or higher) must exist on the
installation system hard disk.
PRODUCT POSITIONING
PC DOS Version 6.1 should be considered cross-industry and in OEM
channels as the primary operating system for the entry level IBM and
IBM-compatible personal computer systems.  PC DOS Version 6.1 should
also be considered as the operating system for non-entry IBM and
IBM-compatible systems, when advanced solutions, very large memory,
storage protection and multi-tasking are not required.
       The PC DOS kernel is based off the MS (1)-DOS 6 kernel and is
compatible with Windows (1) 3.X, Windows Applications, DOS extenders
and DOS applications.
       IBM is committed to DOS and DOS customers.  IBM is making a
real investment in upgrading DOS users with state-of-the-art
utilities and hardware support (PEN, PCMCIA).
       PC DOS Version 6.1 features competitive, award-winning DOS
utilities, which surpass those offered in the MS-DOS 6 product.

TECHNICAL INFORMATION
SPECIFIED OPERATING ENVIRONMENT
MACHINE REQUIREMENTS:  PC DOS Version 6.1 will operate on all
Intel-based personal computers (8088, 286, 386, and higher).
       The minimum processor system memory required for PC DOS
Version 6.1 installation is 512KB.  A new system (one without a
previous version of DOS installed) should also have a 720KB, 1.44MB
or 2.88MB 3.5-inch or a 360KB or 1.2MB 5.25-inch 'A:' diskette drive.
The PC DOS Version 6.1 Upgrade requires a system with a prior version
of DOS (Version 2.1, or higher) installed on the hard disk.
Installation on upgrade systems can occur either from any diskette
drive or from the network to the hard disk.
PROGRAMMING REQUIREMENTS
COMPATIBILITY:  PC DOS Version 6.1 maintains upward compatibility
with prior versions of IBM DOS.  Support of functions supported on
previous levels will be continued, unless a specific function is no
longer supported by IBM.  Functions no longer supported in PC DOS
Version 6.1 include QBASIC and BASICA.  However, QBASIC and BASICA
from prior versions of DOS should continue to run compatibly with PC
DOS Version 6.1.
LIMITATIONS:  Applications supported on previous levels of DOS should
run compatibly with PC DOS Version 6.1.  However, with each release
of DOS, adding new features introduces some incompatibilities.  Below
is a list of changes that may cause compatibility problems.
o   A20 Gate Handling.
           DOS 5.0 toggled the A20 line on and off as needed and
    resulted in a performance penalty but aided compatibility with
    older applications that made assumptions about the state of A20.
    PC DOS Version 6.1, when loaded high (DOS=HIGH), keeps the A20
    line enabled for performance reasons.  If users find that this is
    a problem they should load DOS low (DOS=LOW).
o   No BACKUP.COM
           The BACKUP command has been replaced with the new
    full-screen backup program CPBACKUP.  CPBACKUP is superior in
    every way to BACKUP but incompatible, both in name, switches and
    backup format.  To enable users to restore backups made with
    previous releases of DOS the RESTORE command will be shipped as
    part of PC DOS Version 6.1.  Also if the user has BACKUP.COM, it
    will not be deleted when PC DOS Version 6.1 is installed.
o   New SMARTDRV
           The SMARTDRV disk cache program is redesigned totally
    causing the invocation and command line options to change.
    Install will automatically make the necessary changes to
    CONFIG.SYS and AUTOEXEC.BAT.
o   MIRROR replaced with DATAMON
           Some of the function of the DOS 5.0 MIRROR command is

    integrated into DATAMON.  Users that used to run MIRROR will need
    to run DATAMON instead.
o   EDIT replaced with E
           The DOS 5.0 full-screen editor EDIT is replaced in PC DOS
    Version 6.1 with E.  E is superior to EDIT in functionality but
    has a different user interface.  Users that select EDITOR from
    the DOSSHELL and expect EDIT will get E instead.  Install will
    not delete the users DOS 5.0 EDIT and QBASIC so current EDIT
    users can still run it.  E was purposely not named EDIT to make
    this possible.
o   No BASICA or QBASIC
           PC DOS Version 6.1 will not ship any BASIC interpreter.
    Customers that already have DOS installed can still run their
    BASIC or QBASIC product because install does not delete it.
o   Disk Compression
           Compressed disks represent a departure from current DOS
    versions.  Users who compress their hard disk will not be able to
    boot an older version of DOS and view files on their hard disk.
    Compressed diskettes are also possible with PC DOS Version 6.1
    but pose no compatibility problem since they contain a TSR
    program which will allow the diskette to be read by systems
    running older versions of DOS.

SERVICEPAKS (CSDS):  Corrective Service Diskettes, referred to as
ServicePaks, will be released as needed during the period of service
for the product.  ServicePaks contain accumulated 'code fixes' during
that period.  ServicePaks are installed by the customer at the
customer's location using a CSD Installation Program.  Notification
of the availability of the latest ServicePak will be posted on the
PCC BBS and TalkLink Bulletin Board System.
       ServicePaks may be obtained from one of the following sources:
o   PS Programming Support Center
           A call is placed to the PS Programming Support Center,
    800-992-4777, by an end user with a problem.  If IBM Level 2
    support has determined that a ServicePak is available that fixes
    the problem reported, the customer can receive the latest
    ServicePak.  An order is placed on the Retain file and sent to
    the CSD distribution center in Boulder, Colorado.  A Valid PMR
    number is a prerequisite for placing an order in Retain for a
    ServicePak.  The ServicePak is then mailed to the end user from
    the distribution center in Boulder.  The mailing address is that
    which was reported to IBM at the time the problem was submitted.
    The following can obtain ServicePaks using the methodology just
    described:
    -   Dealers registered as Technical Advisors
    -   Dealers not registered as Technical Advisors
    -   Registered Technical Coordinators
    -   IBM representatives
    -   Any end user who has acquired a license to PC DOS
        Version 6.1.
o   The Dealer or Point-of-Sale
           ServicePaks may be obtained from authorized dealers.  The
    end user may be asked by the dealer to furnish the required
    diskettes.  The Dealers have the following sources for obtaining
    ServicePaks.
    -   Dealers who are not Technical Advisors
        --  PS Programming Support Center
        --  Download from the Electronic Bulletin Board System (PCC
            BBS)
            o   404-835-6600, before September 1993
            o   919-517-0001, after September 1993.
    -   Dealers who are registered as Technical Advisors
        --  Using The PCC BBS Electronic Ordering System
        --  Download from the Electronic Bulletin Board System (PCC
            BBS)
o   Obtaining ServicePaks Via PCC BBS
           The PCC BBS is available 24 hours-per-day.  Registered
    Technical Advisors have access to the Bulletin Board System which
    offers a menu of services as part of the Technical Advisor
    program.  Dealers who are not Technical Advisors and all other
    end users have access to the Bulletin Board System on a toll call
    basis.  The toll number for the PCC BBS is 404-835-6600 before
    September 1993, and 919-517-0001 after September 1993.
    Requirements for asynchronous electronic connection to the
    Bulletin Board System are:
    -   A modem that supports 1200 to 9600 baud communication
    -   Communication software that supports 8-bit file transfer
    -   A switched telephone line
    -   The modem should be set at
        --  Eight data bits
        --  No parity
        --  One-stop bit
        --  Standard transmission speed from 1200 to 9600 baud.
           The end user is instructed to 'refer to the bulletin
    titled CORRECTIVE SERVICE INFORMATION on the Bulletin Board

    System for instructions once connected'.
o   Downloading ServicePaks (CSDs) from the PCC Bulletin Board System
           Registered Technical Advisors have this service as one of
    the services available on the Technical Advisor Menu.  Other end
    users, including dealers who are not registered Technical
    Advisors may select this function after connecting to the
    Bulletin Board System on a toll call basis.  The CSD download
    includes the actual corrective service diskette in binary image,
    a README file with instructions to the end user in how to perform
    the installation and a licensed program that converts the binary
    images to diskette at the receiving workstation.  After the
    download has completed, the end user is then told how to do the
    installation with information contained in the README file.
o   Electronic Ordering of ServicePaks (CSDs) on the PCC BBS
           Dealers who are registered Technical Advisors may order
    CSDs as one of the services provided on the Technical Advisor
    menu.  The Dealer specifies his or her name and mailing address.
    A program operating on the server generates a file which is
    basically the same file created by the Retain system when a level
    2 support person places an order for a CSD.  The difference is
    that with the electronic ordering system, a valid PMR number is
    not a prerequisite to order a CSD.  The Retain file is then sent
    by electronic file transfer to the VMNODE in Boulder that
    contains the CSD ordering program.  A CSD mail order is then
    issued to the name and address specified in the file that was
    electronically generated.  Post office box numbers are not
    considered valid addresses by the Boulder CSD distribution
    system.
o   Obtaining ServicePaks (CSDs) from the TalkLink Bulletin Board
    System
           Customers who subscribe to TalkLink receive a package that
    includes the communications program as well as instructions on
    how to connect to TalkLink.  Customers download ServicePaks from
    TalkLink by selecting the ServicePak from the menu of services
    offered on the TalkLink software libraries.
o   Obtaining ServicePaks (CSDs) from the local IBM office
           Any end user who has acquired a license to PC DOS
    Version 6.1 may obtain the latest level ServicePak from a local
    IBM office if the end user has a problem and a ServicePak is
    available that fixes the problem.
           IBM representatives supporting large accounts have ready
    access to ServicePaks (CSDs) on VMPCPROD.

    effect.  The customer also has the option of ordering a Proof of
    Additional License certificate, in which case, the ICA is not
    required.
o   Documentation -- separate documentation without program
    diskettes.
o   Program Package Upgrade  -- program diskette with documentation.

IBM EDUCATION FULFILLMENT CENTER:  The announced program is eligible
to be ordered through the IBM Education Fulfillment Center.  Please
note that availability through the IBM Education Fulfillment Center
may not coincide with the programming availability dates noted in
other sections of this document.
       The IBM Education Fulfillment Center is the order processing
location for selected Personal Computers and related
hardware/software for eligible education end-users.
PROGRAM UPGRADE
       The program package upgrade option allows currently licensed
users of all prior IBM and compatible DOS versions to obtain the new
function for a program upgrade charge.  For most users, the upgrade
option is fulfilled via the PC DOS Version 6.1 Upgrade, a separately
packaged program.  This program upgrades the user from prior IBM and
compatible DOS Versions 2.1, or higher.  The PC DOS Version 6.1
Upgrade program requires that one of these previous DOS versions is
present on a fixed disk prior to installing the upgrade.  The
customer is authorized to run both the prior DOS program and the PC
DOS Version 6.1 Upgrade program on the same system unit.  However,
separate transfer of either program is not allowed.
       The program may be obtained through IBM Authorized Personal
Computer Dealers and Industry Remarketers beginning July 26, 1993.
Orders will be accepted after July 26, 1993.
       Additionally, end users may order the PC DOS Version 6.1
Upgrade program at the single unit price by calling the PS/2 (R) Help
Center, 800-772-2227.
NOTE: Because the PC DOS Version 6.1 Upgrade program will not allow
end users with DOS versions prior to DOS 2.1 and/or end users not
having fixed disks to perform the upgrade, the following special
procedure has been put in place.
       End users may call the PS/2 Help Center, 800-772-2227 and
order the PC DOS Version 6.1 Upgrade program package at the single
unit price of the PC DOS Version 6.1 Upgrade program.  In this case,
the end user will be required to furnish proof of license of a
previous version of DOS.  That proof of license can be a 'Proof of
License' or the cover page of their previous DOS manual.  Only
originals will be accepted.  Upon receipt of the required proof of
license, the order will be filled.
       Refer to Ordering Information for ordering details.
       To receive program package upgrades at a discount, the ICA and
a Volume Discount Addendum with the appropriate volume discount
exhibit must be in effect.
       To receive PC DOS Version 6.1 Upgrade additional license
upgrades at a discount, the ICA and a Volume Discount Addendum with
the appropriate volume discount Exhibit must be in effect.  The total
quantity of upgrades acquired for a specific program may not exceed
the total quantity of program packages and additional licenses
previously acquired for that program.
       Additional license upgrades can be ordered through an
authorized remarketer.
