NOTES ON SETUP-------------------------------------------------------------
CREATING THE UNINSTALL DISK(S)
If you use a bad disk to create the Uninstall disk during Setup,
you may not be able to successfully uninstall MS-DOS 5.0. Be sure to use an
unformatted or newly formatted disk.
A DIRECTORY CALLED OLD_DOS.1 IS CREATED BY SETUP
A directory called OLD_DOS.1 is created by Setup during the installation
of MS-DOS 5.0. The files in this directory, in combination with the files
on your Uninstall disk, can be used to restore your old DOS.
Do not remove or alter the OLD_DOS.1 directory on your hard disk if you
think you might reinstall your old DOS. After you remove the directory,
reinstalling your old DOS is not possible. You can delete the OLD_DOS.1
directory at any time by typing CLEANUP at the command prompt.
SETUP MAY CREATE MULTIPLE OLD_DOS DIRECTORIES
If you upgrade to MS-DOS 5.0 more than once, without using CLEANUP to
delete previous OLD_DOS directories, a new directory will be created each
time you upgrade. Subsequent OLD_DOS directories will be named OLD_DOS.2,
OLD_DOS.3, and so on.
If you have run the upgrade several times on the same system and have
created several Uninstall disks in the process, be sure to use the most
recent Uninstall disk to recover your system.
USING CLEANUP TO REMOVE OLD DOS INFORMATION
After you have used MS-DOS 5.0 and are confident that you will not need
to restore your previous version of DOS, you can use the CLEANUP program to
remove your old DOS from your hard disk. To remove the old DOS from your
hard disk, type CLEANUP at the command prompt, press ENTER, and follow the
directions.
You will not be able to restore your previous DOS after running CLEANUP.
OLD LINK.EXE VERSIONS MAY BE LEFT IN PATH
If you are running a compiler and it fails, you may have an old version
of LINK.EXE in your DOS subdirectory. MS-DOS Setup puts the DOS directory
at the front of the path in your AUTOEXEC.BAT file. The LINK.EXE file that
was in the DOS directory before you installed MS-DOS 5.0 may be put ahead
of the location of the LINK.EXE file you want to use.
LINK.EXE is not shipped with MS-DOS 5.0.
WINA20.386 FILE
When installing upon systems capable of running Windows in Enhanced mode
MS-DOS 5.00 will place a read only file called WINA20.386 in the root
directory. This file provides support for Windows when it is running in the
enhanced mode and has to stay in the root.
MANUALLY UNPACKING MS-DOS 5.0 FILES:
Files on MS-DOS 5.0 master disks that have extensions ending with an
underscore (_) are in a compressed format. To retrieve a single file from
the MS-DOS 5.0 master disks, use the EXPAND utility located on Disk 5.
Syntax: expand [drive1:][path1]infile [drive2:][path2]outfile
[drive1:][path1]infile Specifies the location and name of the
compressed file you want to expand
[drive2:][path2]outfile Specifies the destination and new name
of the expanded file
Example: expand a:\redir.ex_ c:\dos\redir.exe
SETTING UP MS-DOS 5.0 ON OS/2 SYSTEMS----------------------------------
RUNNING THE UPGRADE ON AN OS/2 SYSTEM
If you install the upgrade over IBM OS/2 1.0 you will not be able to
uninstall. This is not a problem for MS OS/2 1.0 or for IBM and MS OS/2
1.1 and later versions. You can work around this by renaming the IBM OS/2
1.0 system files, IBMBIO.COM and IBMDOS.COM, to something else so the setup
program does not confuse them with DOS system files
If you run the uninstall on a system which had OS/2 on it before the
upgrade running chkdsk may show some lost extended attributes. This will
happen whenever a file which had extended attributes under OS/2 was altered
under dos before the uninstall
MS-DOS 5.0 AND OS/2 DUAL BOOT
OS/2 1.1 and Compaq OS/2 1.21 dual boot installation programs don't work
with MS-DOS 5.00. MS OS/2 1.21 dual boot works fine.
NOTES ON WINDOWS 2.X-------------------------------------------------------
RUNNING WINDOWS/286 WITH MS-DOS 5.0
If you run Windows/286 on a computer with MS-DOS 5.0, you will need to
run COMMAND.COM from a program information file (PIF). Winoldapp allocates
only about 39K for the COMMAND.COM file, which is not enough for the MS-DOS
5.0 COMMAND.COM.
USING WINDOWS 2.1 RUN-TIME APPLICATIONS WITH MS-DOS 5.0
If you are using Windows 2.1 run-time applications, there may be older,
incompatible, versions of SMARTDRV.SYS and HIMEM.SYS on your hard disk.
An older version of SMARTDRV.SYS will cause an "Incorrect DOS version"
error message to appear on your screen, and SMARTDrive will not install.
An older version of HIMEM.SYS will cause the run-time application not to
run, and may cause other incompatibility problems.
Be sure to change your CONFIG.SYS file so the SMARTDRV.SYS and HIMEM.SYS
files supplied with MS-DOS 5.0 are used instead of those supplied with your
Windows application.
NOTES ON WINDOWS 3.X-----------------------------------------------------
WINDOWS/386 DEBUG VERSION AND MS-DOS 5.0
If you are running the debug version of Windows/386 with DOS=LOW, the
DOS segment will be below the BIOS segment, causing your system to fail.
Call Microsoft Product Support Services at (206)454-2030 for a solution to
this problem.
RUNNING WINDOWS 3.0 REAL MODE IN AN ENHANCED MODE WINDOW
If your computer hangs or gets an application error when running win /r in
an Enhanced Mode VM, it may help if you remove the line "ebios=*EBIOS" in
the 386ENH section of the SYSTEM.INI file. However, this may make it
impossible to run other programs after exiting.
THE SETVER COMMAND---------------------------------------------------
With the SETVER command, you can control what version MS-DOS reports to
certain programs. SETVER "fools" programs that rely on a certain version
of DOS into running under MS-DOS 5.0.
DISK PARTITIONING SOFTWARE-------------------------------------------
MS-DOS 5.0 Setup may not be able to directly upgrade your hard disk
if one of the following disk utilities was used to set up hard disks
on your system:
Manufacturer Name Device Driver
---------------------------------------------------------------------
Ontrack Disk Manager DMDRVR.BIN
Storage Dimensions SpeedStor SSTOR.SYS or HARDRIVE.SYS
Golden Bow Systems Vfeature Deluxe FIXT_DRV.SYS
Hewlett-Packard MultiVol MULTIVOL.SYS
Hewlett-Packard Volume Expansion HARDRIVE.SYS
If MS-DOS 5.0 Setup detects a disk partition created by one of the
above utilities, it will refuse to upgrade your hard disk
automatically. In order to install MS-DOS 5.0, follow the detailed
steps outlined below.
IDENTIFYING THE DISK UTILITY
You may already know which disk utility was used to set up your hard
disk. If not, look in your CONFIG.SYS file for one of the device
driver names in the above table. For example, if the line
"DEVICE=SSTOR.SYS" appears in your CONFIG.SYS file, the SpeedStor
disk utility was used to set up your hard disk. If you find
HARDRIVE.SYS in your CONFIG.SYS file, you must determine whether
the device driver came from Hewlett-Packard (HP DOS 3.3) or Storage
Dimensions.
UPGRADING TO MS-DOS 5.0
Procedures to determine whether you can upgrade your system and to
carry out the upgrade vary between the disk utilities. Each is
discussed separately below.
Note: MS-DOS 5.0 Setup requires at least 2.5 MB of free space in
your boot partition (drive C). If you have a very small boot
partition, you may need to repartition your hard disk to create a
larger boot partition before upgrading to MS-DOS 5.0.
Setup utility comments out the device driver line in your CONFIG.SYS
file after the installation is successfully completed.
UPGRADING DISK MANAGER
If you are currently running DOS version 4.0 or 4.01, you can upgrade
your hard disk to MS-DOS 5.0 by running Setup with the /u switch, as
follows:
setup /u
If you are running an earlier version of DOS, you should contact
Microsoft Beta support for DOS 5.0 compatible disk manager drivers
(provided to MS by Ontrack systems).
UPGRADING SPEEDSTOR
If you are currently running DOS version 4.0 or 4.01, you should have
no difficulty upgrading to MS-DOS 5.0 by running setup with the /u
switch, as follows:
setup /u
If you are running an earlier version of DOS, you should contact
Microsoft Beta support for DOS 5.0 compatible disk manager drivers
(provided to MS by storage dimension).
UPGRADING MULTIVOL or VOLUME EXPANSION
These disk utilities were distributed with HP DOS versions 3.2 and
3.3. Hewlett-Packard recommends that you repartition and reformat your
hard disk with MS-DOS 5.0, eliminating the need for MultiVol or
Volume Expansion. To do this, carry out the following steps:
* Install MS-DOS 5.0 on floppy disks. You can do this by running
MS-DOS 5.0 Setup. Although Setup will refuse to upgrade your hard
disk, it will install DOS on floppy disks.
* Back up your hard disk using the HDBACKUP program provided with MS-DOS
5.0 or some other backup utility. The program HDBACKUP.EXE can be found
on UPGRADE DISK 1 and can be run by typing in HDBACKUP at the A:> prompt.
Backups created this way can be restored with the dos RESTORE command.
* Boot from the MS-DOS 5.0 startup floppy disk you created.
* Run FDISK.
* Delete non-DOS partitions.
* Create new partitions.
* From the MS-DOS 5.0 floppy disk, run FORMAT to format each new
partition.
* Restart your system from the hard disk (remove floppy disks from
drives first).
* Run MS-DOS 5.0 Setup. Setup will upgrade your hard disk.
* Restore the files from the deleted partitions, using the backup
copies you created.
UPGRADING VFEATURE DELUXE
Current versions of Vfeature Deluxe is not compatible with MS-DOS
5.0. Golden Bow Systems is planning to upgrade the software to take
advantage of MS-DOS 5.0 advanced features. Contact Golden Bow system
for information about Vfeature upgrades. Until the upgrade is
available, you can install MS-DOS 5.0 on floppy
disks. However, you may not be able to access your hard disk while
running MS-DOS 5.0.
HARD DRIVE PARTITIONS WITH LOGICAL SECTORING---------------------------
If the version of DOS you were using before upgrading to dos 5 used
logical sectoring partitions that were larger than 32MB on the hard drive
you should never boot with your previous dos and then access the hard drive.
Because dos 5 upgrade has changed the structure of your hard drive partition
doing this could very easily destroy information on the drive. At this point
in time we know that NEC, Toshiba, Wyse and Zenith Dos' use logical sectoring
on large hard drive partitions. This is by no means a complete list and will
be enlarged.
MAKING YOUR HARDWARE COMPATIBLE WITH MS-DOS 5.0----------------------------
INTEL ABOVEBOARD
If you have an Intel Aboveboard in your system you will need to run Intel's
Aboveboard setup program after installing dos 5 in order to access the memory
on the board. This needs to be done because the Dos 5 installation program
overwrites the Aboveboard's initilization information which is stored on your
harddrive.
HP VECTRA CS MODEL 20
The Hewlett Packard portable Vectra CS Model 20 requires a 1.44Mfloppy
in drive A at boot time for MSDOS FORMAT, DISKCOPY and DISKCOMP to recognize
the drive as a 1.44MB floppy drive. Failure to do so will make FORMAT,
DISKCOPY and DISKCOMP think that the drive is a 720K floppy drive and prevent
their proper operation with 1.44MB floppies. Hewlett Packard's version of
MS-DOS 5.0 will not have this requirement.
LOGITECH C7 MOUSE
If you are unable to use a Logitech C7 mouse, contact the company to
obtain an updated mouse driver. You will need to get version 5.0 or later.
ADAPTEC CONTROLLER BOARDS
If you are using an Adaptec controller board with two hard drives
attached and are using expanded memory (EMS), you may need to obtain
Adaptec's adaptec.sys device driver. For more information, contact your
Adaptec dealer or distributor or call Adaptec's technical support
hotline at 408/945-2550.
101-KEY KEYBOARDS AND QBASIC/EDIT
If you are unable to use the arrow keys on your numeric keypad when
running Qbasic or EDIT, Microsoft offers a TSR called FIXSHIFT.COM which
may help. To obtain FIXSHIFT.COM call Microsoft Product Support at
(206)454-2030
COREL SYSTEMS DRIVERS
If you are having trouble with a Corel System driver for a large
capacity drive (WORM, Winchester, etc.) you may need to obtain an updated
driver from Corel Systems.
PLUS DEVELOPMENT HARDCARD II
If you are having trouble with Plus Development's Hardcard II when
running EMM386.EXE, you will need to add the option X=D700-D7FF on the
DEVICE= line for EMM386.
VIDEO 7 VGA CARDS
If you are having trouble with MS-DOS Shell and the Microsoft mouse when
using a Video7 VGA card, it may help if you use the /Y option on the mouse.
PROCOMM FLOPPY DRIVES
If you have trouble with ProComm floppy drives you may need to obtain
an updated driver from ProComm.
MAKING YOUR SOFTWARE COMPATIBLE WITH MS-DOS 5.0----------------------------
SOFT ICE BY NU-MEGA
If you are using Nu-Mega's Soft Ice program you should not load it after
HIMEM.SYS on a Compaq system when you are using SMARTDRV.SYS. Soft Ice can
corrupt the disk cache in this situation, resulting in a corrupted hard drive.
SOFTWARE CAROUSEL
Software Carousel will lock up when running under MS-DOS 5.0 unless
SETVER has been used to report version 4.00 to it.
Example: SETVER C: CAROUSEL.EXE 4.00
LOTUS METRO, LOTUS EXPRESS, AND IBM DISPLAYWRITE III
These software packages do not support the extended ROM BIOS for 101-key
keyboards. If you have trouble with them, add the following line to your
CONFIG.SYS file and restart your computer:
SWITCHES=/K
This will instruct MS-DOS 5.0 not to use the extended ROM BIOS. The
applications will work, but you will not be able to access the F11 or F12
keys through MS-DOS.
MS-DOS MULTITASKING SOFTWARE:
If you are using software that provides multitasking support for MS-DOS,
do not enable the switcher in MS-DOS Shell. The multitasking system and
MS-DOS SHELL task swapping are likely to conflict.
ASYNCHRONOUS I/O and DOSSHELL.EXE TASK SWITCHING
The MS-DOS Shell task switcher does not support switching of programs
performing asynchronous communications. This includes all terminal
emulation software such as SmartCom, Procomm Plus, and server/client
software such as Laplink and Blast. The MS-DOS Shell task switcher should
not be enabled if you are using asynchronous communications programs.
GAZELLE SYSTEMS QDOS II:
QDOS II is a DOS version-specific application. Only versions of QDOS II
that support MS-DOS 4.xx will work correctly with MS-DOS 5.0.
MICROSOFT CODEVIEW 3.00:
If you are using Microsoft Codeview 3.0 to debug applications that use
expanded memory, and are using the EMM386.SYS memory manager of MS-DOS 5.0
in AUTO mode, you may experience some problems. Whenever using Codeview to
debug EMS applications you should either turn EMM386 on before debugging or
use the /d or /e switches on Codeview 3.0.
RAID AND MS-DOS 5.O (IBETA)
If you are a raid user and are upgrading from MS-DOS 3.x, copy the
NISAMR.EXE file from \\dos5server\beta. If you are upgrading from DOS 4.x,
you probably have this file and will not need to get it.
QUARTERDECK MANIFEST:
Versions of this application previous to 1.01 are closely tied to
internals specific to earlier versions of DOS and do not work with MS-DOS
5.0. Quarterdeck Manifest v1.01 will work on MS-DOS 5.00. For an upgrade to
v1.01 contact Quarterdeck
QUARTERDECK QEMM
Versions of Qemm prior to 5.11 have problems when the HIMEM.SYS file is
loaded with the /INT15=xxxx option. Add the QEMM option MEMORY=yyyy to the
DEVICE=QEMM.SYS line in your CONFIG.SYS file, where yyyy = xxxx - 64. Or
can update your Qemm to version 5.11.
The buffers program supplied with some versions of Qemm should not be
used with MS-DOS 5. If you were using this program previous to upgrading to
MS-DOS 5.0 you will need to increase your dos BUFFERS= line in your
config.sys. We suggest BUFFERS=20 as a new setting.
KINGSTON MEMORY BOARD EMS DRIVER:
The Kingston EMSDRVR.SYS driver is incompatible with the MS-DOS 5.0
HIMEM.SYS file. You can use the MS-DOS 5.0 EMM386.SYS file to access EMS
memory instead of the Kingston diver.
SOFTWARE THAT ACCESSES EXTENDED MEMORY VIA INT 15
Some software that uses extended memory, such as Paradox, Oracle, QEMM,
or Turbo EMS, does so using interrupt 15. To use this type of software
with MS-DOS 5.0 loaded high, you can use the HIMEM.SYS /INT15=xxxx switch.
The /INT15 switch allocates the specified amount of extended memory for
the INT15h interface.
It may also be necessary to use options on the particular software to
specify the amount of extended memory accessible through INT15. This can
be done using the /M switch with Turbo EMS, and the MEMORY option
with QEMM.
386MAX:
In some cases, after loading a program high with 386LOAD.COM, the loaded
program will report "Incorrect DOS version." If this occurs use the SETVER
command to set the version number for 386MAX to the lower version required
by the program reporting the error.
If a program is loaded high using 386LOAD.COM, the DOS version number
reported by SETVER will not be passed to it by 386MAX . This happens
because the 386MAX reports the version it sees to programs that have been
loaded high, not the version they see.
WARNING: After this has been done, all programs loaded by 386LOAD.COM
will be reported this new version number
The Maxhi.exe program supplied with versions of 386MAX prior to 5.0
should not be used with MS-DOS 5.0 as it will cause the machine to hang.
TANDY DESKMATE
Versions of Deskmate prior to 3.0.2 incorrectly calculated disk space
size for large disks. If problems occur writing files to a disk because
Deskmate reports that there is not enough disk space, contact Tandy to get
the most recent version of Deskmate.
NORTHNET ATLAST!
If you experience problems with Northnet's Atlast! upper memory manager,
contact Northnet for an upgrade.
PC-TOOLS BACKTALK
Loading PC-Tools Backtalk into upper memory blocks with the LOADHIGH
command may cause your machine to hang. Usually this will only happen if
you have filled up the rest of the UMB space with other device drivers and
TSR's. You should load Backtalk in conventional memory and fill the UMB
space with other device drivers or TSR's.
MICROSOFT CD-ROM EXTENSIONS
While any version of MSCDEX.EXE that worked under MS-DOS 4.x will
function in most situations under MS-DOS 5, there are known problems with
MSCDEX.EXE when using it with the /s option to run a CD-ROM drive as a
network server. This function will not work in MS-DOS 5.00 until a new
version of MSCDEX.EXE is written.
SOFTLOGIC SOLUTION'S DISK OPTIMIZER
Versions of Softlogic Solutions Disk Optimizer prior to 4.05 would give
the message "File Allocation Table Contains Invalid Information. Run
CHKDSK". If you encounter this problem you will need to contact Softlogic
for an upgrade.
MOUNTAIN HIGH'S AUTORUN.EXE
If you experience problems with autorun.exe, a tape drive backup program
written by Mountain High, you will need to contact the company to obtain
an upgrade
BORLAND'S TURBO DEBUGGER 386
Borland's Turbo Debugger 386 is configuration dependent and will need to
be reinstalled after upgrading to MS-DOS 5.00 or you may experience machine
hangs while running the debugger.
