1. Q. How can I find more information on the new MS-DOS 6.0 commands?
A. You can find information on all MS-DOS commands by typing
"help" (without the quotation marks) at the MS-DOS command
prompt. If you want information on a specific command, type
"help" (without the quotation marks) followed by the command
name to go directly to that section in the MS-DOS Help program.
2. Q. How do I add the Windows-based utilities after I install MS-DOS
6.0?
A. The MS-DOS 6 Upgrade includes Windows-based versions of
Microsoft Backup, Microsoft Anti-Virus, and Microsoft Undelete.
To install these programs after you have installed MS-DOS 6.0,
insert Setup Disk 1 in your floppy disk drive. At the MS-DOS
command prompt, type the following command and press ENTER
drive: setup /e
where "drive" is your floppy disk drive.
For more information on the Windows-based utilities, refer to
the "Microsoft MS-DOS 6 User's Guide."
3. Q. When I try to use Microsoft Backup for MS-DOS, I receive the
message "DMA Buffer Size Too Small." How can I correct this
problem?
A. You can correct this problem by increasing the size of the
direct memory access (DMA) buffer used by EMM386.EXE. To do
this, use the following steps:
1. Use an ASCII text editor, such as MS-DOS Editor, to open
your CONFIG.SYS file.
2. Locate the EMM386.EXE command line.
3. At the end of the EMM386.EXE command line, add the following
parameter:
/d:64
4. Save the CONFIG.SYS file, then quit the text editor.
5. Restart your computer.
For more information about Microsoft Backup for MS-DOS, refer
to the "Managing Your System" chapter in the "Microsoft MS-DOS
6 User's Guide."
4. Q. When I try to use Microsoft Backup for Windows, I receive the
message: "DMA Buffer Size Too Small." How can I correct this
problem?
A. You can correct this problem by increasing the size of the DMA
buffer used by the extended memory manager and then modifying
your system initialization file (SYSTEM.INI). To do this, use
the following steps:
1. Use an ASCII text editor, such as MS-DOS Editor, to open
your CONFIG.SYS file.
2. Locate the EMM386.EXE command line.
3. At the end of the EMM386.EXE command line, add the following
parameter:
/d:64
4. Save the CONFIG.SYS file, then quit the text editor.
5. Use an ASCII text editor to open your SYSTEM.INI file, which
is located in your Windows directory.
6. Locate the [386Enh] section and add the following line after
the section heading:
DMABuffersize=64
7. Save the changes to the SYSTEM.INI file, then quit the text
editor.
8. Quit Windows if you haven't already done so, and restart
your computer.
For more information about Microsoft Backup for Windows, please
refer to the "Managing Your System" chapter in the "Microsoft
MS-DOS 6 User's Guide."
5. Q. Now that I have upgraded to MS-DOS 6.0, my CD-ROM drive no
longer works correctly. Why is this occurring and how can I
correct the problem?
A. If MS-DOS 6 Upgrade Setup finds the Microsoft Compact Disc
Extensions (MSCDEX) in your AUTOEXEC.BAT file, it updates
MSCDEX.EXE to version 2.22. This version may be incompatible
with your CD-ROM drive's device driver.
If you did not experience incompatibility problems with your
earlier version of MS-DOS, you can avoid problems by replacing
the new version of MSCDEX with your previous version. If you do
so, you must also add the following command to your CONFIG.SYS
file and then reboot your computer:
device=c:\dos\setver.exe
This problem may also be caused by a memory conflict involving
MSCDEX. If you load MSCDEX into the upper memory area (UMA) and
encounter CD-ROM problems, try loading it into conventional
memory.
Contact the manufacturer of your CD-ROM drive to determine
whether your drive's device driver is compatible with MSCDEX
version 2.22.
6. Q. Can I load MSCDEX version 2.22 into the UMA?
A. You can use the LOADHIGH command to load MSCDEX version 2.22
into the UMA, but only on an 80386 or 80486 machine with
available extended memory and an upper memory block (UMB)
provider (such as EMM386.EXE, Qemm[TM], or 386MAX[R]).
If LOADHIGH fails to load the program into the UMA, use the
MemMaker program to optimize your system. MemMaker may be able
to find additional UMBs or rearrange the order in which
programs are loaded so that MSCDEX can load into the UMA.
For more information on optimizing your system and using
MemMaker, refer to the "Making More Memory Available" chapter
in the "Microsoft MS-DOS 6 User's Guide."
7. Q. Why do I receive the message "Out of memory" when I use the
Microsoft Defragmenter, Anti-Virus, and Undelete programs?
A. The message "Out of memory" means that the program does not
have access to enough conventional memory. You must optimize
your system to free more memory. For information on this
procedure, refer to the "Making More Memory Available" chapter
in the "Microsoft MS-DOS 6 User's Guide."
8. Q. I entered the command DELTREE *.* /y and all files on my
current drive were deleted. Why did this happen?
A. The DELTREE command allows you to delete entire directories--
including all files and subdirectories--with one command. When
you press ENTER, DELTREE prepares to delete all files and
directories on the current drive. Before it does, it issues a
message asking you to verify that you want to delete all the
files and directories from the current drive. However, the /y
parameter bypasses this verification message.
For more information about the DELTREE command, refer to the
"Microsoft MS-DOS 6 User's Guide," or type "help deltree"
(without the quotation marks) at the MS-DOS command prompt.
Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!
This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.
But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
