IBM DOS Version 5.00 and Upgrade
IBM DOS Version 5.00 is the single-task operating system of choice for the IBM
Personal Computer, Personal System/2 (PS/2), and the Personal System/55 (PS/55)
families and is compatible with the Personal System/1 (PS/1). This version of
IBM DOS provides the capability on most systems for significantly more
application memory space than on many previous versions of IBM DOS. It offers
an enhanced menu-based user interface, improved memory management, improved
performance and improved functions. A new IBM DOS Version 5.00 Technical
Reference is available separately.
IBM DOS Version 5.00 Upgrade is the full IBM DOS Version 5.00 product at a
significantly reduced price. Installation specific programs allow and aid end-
users with a prior version of IBM DOS (Version 2.1 or higher) to upgrade to IBM
DOS Version 5.00 on their system hard disk.

DESCRIPTION
USER PRODUCTIVITY
INCREASED APPLICATION SPACE: IBM DOS Version 5.00, the tenth release of IBM's
Disk Operating System (DOS), has more functions and is easier to use, and it is
smaller and faster than its predecessors. In response to customer demand for
more application space, IBM DOS Version 5.00 reverses the DOS memory growth
trend. Through utilization of High Memory Area (HMA) and Upper Memory Blocks
(UMBs), IBM DOS Version 5.00 can provide significantly more application space in
the 640KB conventional memory area than previous versions of DOS. It
effectively reduces DOS size to below that of DOS Version 3.30 in conventional
memory. HMA is available on systems 80286 or greater processor and 1MB of
memory. UMB is available on systems with 80386 or greater processor.
IMPROVED PERFORMANCE: The EMM386 Expanded Memory Manager in IBM DOS Version
5.00 significantly increases teh Expanded Memory Support (EMS) performance for
IBM DOS Version 5.00 customers. In addition, EMM386 allows parts of DOS, device
drivers and other programs to be relocated into Upper Memory Blocks of the
reserve area (640K-1MB). This ability also makes more conventional memory
available to other applications for performance improvements. Conflicts with
EMS support and extenders is removed through incorporation of Virtual Control
Program Interface (VCPI) in EMM386.
Improved hard disk performance can be achieved through the use of the IBM DOS
Version 5.00 disk caching program SMARTDRV. Systems with more than 1MB of
memory should utilize a disk caching program to achieve optimum hard disk
performance.
Note: XMA2EMS is not shipped with IBM DOS Version 5.00 The EMS options for
80286 systems ship EMS drivers or XMA2EMS compatible with IBM DOS Version 5.00.
Note: SMARTDRV is an alternative to the IBMCACHE program shipped with some PS/2
systems. Only one cache program should be used in a system. The end-user
should replace IBMCACHE with SMARTDRV. IBMCACHE does not use extended memory
according to XMS (the eXtended Memory SPecification) and may conflict with IBM
DOS Version 5.00 or with Microsoft Windows.
IMPROVED EASE OF USE: The IBM DOS Version 5.00 Shell has an improved interface,
which operates similar to Microsoft Windows and the OS/2 Presentation Manager.
The IBM DOS Version 5.00 user can manage programs, view the directory structure
of any disk, view the contents of several directories, and navigate through
files and directories quickly. A limited (SUSPENS/RESUME) application task
switcher - task swapper- is provided in the shell that supports multiple
applications.
Note: The task swapper in IBM DOS Version 5.00 does not suspend and swap
terminate and stay resident (TSRs) programs. Some asynchronous communications
programs, local area network (LAN) support programs, and mainframe terminal-
emulation programs or other programs of this type do not run correctly with task
the task swapper. Using them with the task swapper amy cause a system to be
disconnected from the mainframe session and cause data loss.
Installation of IBM DOS Version 5.00 is easier and faster. A new setup program
is provided with online HELP, which guides the user through each step of the
setup process and provides help whenever it is needed.
NEW and IMPROVED DOS COMMANDS, PROGRAMS and UTILITIES : New and improved DOS
commands/programs provide more usability, flexibility and reliability for IBM
DOS Version 5.00 customers.
* New online help for IBM DOS commands through the /? parameter of each
command or via HELP.
* The ATTRIB command allows changing of the system and hidden file
attributes in addition to the read-only and archive attributes.
* The COMP command containes switches for different display modes and can
compare a given number of lines of two files, even if the files are of
different sizes
* Improvements in the DIR command include options to search all subdirec-
tories for files, sorting output, searching by attributes, listing file
names only, bytes-free information and more readable wide output.
* The DISKCOPY command contains an optional switch which causes a write
verify to be performed.
* The new DOSKEY terminate and stay resident program provides command line
recall and edit capabilities. DOSKEY can also be used to create macros
that contain one or more IBM DOS commands.
* EDIT is a new, easy-to-use full-screen IBM DOS editor that allows the
end-user to create, edit, save and print ASCII text files.
Note: EDLIN continues to be shipped with IBM DOS Version 5.00.
* The new EXPAND command expands a compressed IBM DOS Version 5.00 file.
* The new FC command compares two files and displays the difference.
* The FIND command has an added option to provide non-case-sensitive
searches.
* The FORMAT command automatically (unless the/U switch is specified)
saves information neede for the UNFORMAT command (safe formatting).
A quick formatting option, /Q, can speed up the format process. On
newer systems that provide diskette drives with media sensing support
FORMAT determines the media capacity of the unformatted diskettes and
automatically formats the media to that capacity (unless the end-user
specifies otherwise).
Note: Diskettes should not be formatted to sizes other than the size
specified for that diskette. Possible data loss may occur.
* The GRAPHICS command offers more printer types and provides for VGA
graphics display modes.
* The new LOADHIGH command loads a program into the upper memory area.
DEVICEHIGH= in CONFIG.SYS loads device drivers into the upper memory
area. Loading a program or device driver into the upper memory area
leaves more romm in conventional memory for other programs.
* The MEM command displays memory allocated to device drivers and programs
loaded into Upper Memory Blocks.
* The new MIRROR command loads a terminate-and-stay resident deletion
tracking program that saves information for one or more disks. The
UNFORMAT and UNDELETE commands can use this information to restore a
reformmated disk or to recover a deleted file.
* QBasic is a new and improved basic interpreter for IBM DOS Version 5.00.
It reads instructions written in BASIC and interprets them into
executable computer code. It includes extensive online help.
Note: BASICA programs will not run with QBasic. In order to run a
BASICA program with QBasic, the BASICA program must be saved in ASCII
mode. Some BASICA commands may also require changes.
Note: A new BASICA is shipped with IBM DOS Version 5.00. This new
version of BASICA is compatible with previous versions of BASICA shipped
with previous versions of IBM DOS.
* RAMDRIVE replaces the VDISK program shipped with prior versions of IBM
DOS and provides like function. It creates a random-access memory (RAM)
disk in the system's RAM to simulate a hard disk drive. RAM disks, much
faster than hard disk, are temporary.
* The RESTORE command displays a list of files on the backup disk.
* With the new SETVER command, IBM DOS Version 5.00 enables users to run
some old programs that do version checks.
* The new UNDELETE command recovers files previously deleted with the DEL
command.
* The new UNFORMAT command gives the capability for IBM DOS Version 5.00
users to recover accidentally formatted media. Unformat restores only
local hard disk and diskette drives. It cannot be used on network
drives.
A new IBM DOS Version 5.00 Technical Reference is separately available. It
provides reference and system architecture information in a task-oriented manner
for the experienced user, system programmer and application developer, assuming
that the user is familiar with the 8088/8086, 80286 ot 80386 microprocessor
architecture. As with DOS Version 3.30 and DOS Version 4.0, the IBM DOS Version
5.00 Technical Reference contains the DEBUG, LINK, EXE2BIN, SAMPLE>ASM and LIB
programs.
INVESTMENT PROTECTION
SUPPORTS OLD SYSTEMS and OPTIONS: IBM DOS Version 5.00 supports all models
(except PCjr, AT/370 and XT/370) of the IBM Personal Computer and Personal
System/2 families. It is compatible with the Personal System/1 (PS/1), however,
use of IBM DOS Version 5.00 on the PS/1 eliminates use of the PS/1 shell.
SUPPORTS NEW SYSTEMS and OPTIONS: In addition to systems/options supported by
previous IBM DOS releases, IBM DOS Version 5.00 provides support for:
* 2.88 diskette drives
* Diskette media sense
* Read/write optical
MAINTAINS INTERFACES (COMPATIBILITY): IBM DOS Version 5.00 continues to provide
an open system architecture that can be extended via system extensions, device
drivers and future enhancements. It also continues to allow applications to use
DOS extensions. Many application interfaces have been maintained and tested.
IBM DOS Version 5.00 is fully compatible with AccessDOS. AccessDOS is a program
that provides better keyboard, mouse and sound access for persons with physical
disabilities. Some of the features included in AccessDOS are:
* StickyKeys allows the user to press each key separately when performing
multiple key operation. With StickyKeys the user can press the shift
key, then press the 8 key to make an asterisk (*). Without StickyKeys,
the user would have to hold the shift key down while pressing the 8 key.
StickyKeys works with the Shift, Ctrl and Alt keys.
* MouseKeys allows the cursor keys to behave like a mouse. Using the
cursor keys the user can move the cursor around on the screen as if
using a mouse.
* ToggleKeys uses a"beep" to indicate when the Caps, Lock, Num Lock or
Scroll Lock keys are activated or de-activated.
* ShowSounds displays a small musical note in the upper left-hand corner
of the display when the computer "beeps".
* RepeatKeys allows the user to set how fast keys will repeat if held
down. If set to OFF, the repeat function is eliminated.
* SlowKeys allows the user to set the sensitivity of the keyboard.
SlowKeys instructs the computer not to accept a key as "pressed" until
it has been down a specific length of time.
* BounceKeys allows the user to set the sensitivity of the keyboard. This
prevents multiple occurances of the same key unless a specific amount of
time has passed between the first time a key is pressed and when it is
pressed again.
AccessDOS was developed by the Trace Research and Development Center in
cooperation with IBM. This software is offered free of charge and, as such, is
offered as-is and without warranty of any kind. It is available from the
Technical Directory (84F9872 and G84-9872).
LAN COMPATIBILITY: Installation of IBM DOS Version 5.00 in a LAN network may
require updates for the LAN programs on workstations using IBM DOS Version 5.00.
* Users of DOS LAN Requester (DLR) included in OS/2 Server Version 1.3
- OS/2 LAN Server Version 1.30.1 works compatibly with IBM DOS Version
5.00
- OS/2 LAN Server Version 1.3 requires CSD #WR05015 to be applied before
installing with IBM DOS Version 5.00
* Users with IBM PC Lan Program
- IBM PC LAN Program 1.34 works compatibly with IBM DOS Version 5.00.
- IBM PC LAN Program 1.33 requires CSD #IP00755 to be applied before
installing with IBM DOS Version 5.00
PROVIDES EASY UPGRADE: The IBM DOS Version 5.00 Upgrade provides the full IBM
DOS Version 5.00 function with installation specific programs that allow and aid
previous IBM DOS users to upgrade to IBM DOS Version 5.00 at a significantly
lower price. A prior version of IBM DOS (Version 2.1 or higher) must exist on
the installation hard disk.
As a convience to customers who buy the IBM DOS Version 5.00 Upgrade between
June 11, 1991, and December 31, 1991, IBM includes updates for some existing LAN
network files with the upgrade package. Thes files provided with IBM DOS
Version 5.00 Upgrade are interim fixes for compatibility with IBM DOS Version
5.00 only. They do NOT contain fixes for problems other that IBM DOS Version
5.00 compatibility. Customers should contact their LAN vendors for complete
updates to the network files. Compatibility updates for IBM PC LAN Program
Version 1.33, DOS LAN Requester (DLR) included in IBM OS/2 LAN Server Version
1.3, and Novell NetWare are provided with the upgrade package. These upgrades
will not be included with IBM DOS Version 5.00 Upgrade after December 31, 1991.
GROWTH ENABLEMENT: IBM DOS Version 5.00 provides more application space than
IBM DOS Version 4.00 or Version 3.30 on 80286 or greater systems with 1MB or
larger memory. This allows more/or larger applications in the 640KB
conventional memory area. This capability is available through HIMEM
Extended-Memory Manager included in IBM DOS Version 5.00. It provides access to
extended memory and insures that no two programs can use the same part of
extended memory at the same time.
Note: HIMEM might not be compatible with older programs that allocate extended
memory directly, rather than using an extended-memory manager.
SYSTEMS MANAGEMENT
