DOS的一些基础工具

   insert your Windows NT Emergency Repair Disk (which you created when 
   you installed Windows NT) to repair the Windows NT system files.


Procedure 2

1. When you start your computer, choose MS-DOS as your operating
   system.

2. Run Setup by inserting Setup Disk 1 in drive A or B, and typing
   A:SETUP or B:SETUP at the command prompt.


1.9  Setup detects that your computer has a non-MS-DOS
     partition or non-MS-DOS files, and your computer uses
     Windows NT
----------------------------------------------------------
The procedure you use depends on whether you want to preserve
the partition and its files. Find the section below that describes
the configuration you want.

You Don't Want to Preserve the Partition or its Files
------------------------------------------------------
If you don't want to preserve the partition or its files, choose to
remove the partition or files if Setup prompts you to do so. If
Setup doesn't offer you that choice, remove the partition manually
after Setup is complete. For instructions on removing a non-MS-DOS
partition manually, see "Using Fdisk to Configure Your Hard Disk" in
the chapter "Diagnosing and Solving Problems" in the MICROSOFT MS-DOS
USER'S GUIDE.

You Don't Want to Preserve the Partition but Want to Save its Files
-------------------------------------------------------------------
If you want to save the data files, but don't want to preserve the
partition, back up the files, run Setup again, and then choose to
remove the partition or files if Setup prompts you to do so. If Setup
doesn't offer you this choice, remove the partition manually after
Setup is complete. For instructions on removing the partition
manually, see "Using Fdisk to Configure Your Hard Disk" in the
chapter "Diagnosing and Solving Problems" in the MICROSOFT MS-DOS
USER'S GUIDE.

You Want to Preserve the Partition and Its Files
------------------------------------------------
Carry out the following procedure.

NOTE  If the non-MS-DOS partition takes up all the space on your hard
disk, you must reconfigure your hard disk. You can either let Setup do
it for you, as described in the preceding section, or reconfigure it
yourself manually. For instructions on reconfiguring your hard disk
manually, see your Windows NT documentation.

To install MS-DOS 6.22 and preserve your partition or files:

1. Run MS-DOS Setup.

2. When prompted, choose to continue Setup without removing the
   partition or files.

3. After Setup is complete, insert your Windows NT Setup disk 
   in drive A or drive B, and then restart your computer.
   
4. When the Windows NT Setup screen appears, choose Repair, and then 
   insert your Windows NT Emergency Repair Disk (which you created when 
   you installed Windows NT) to repair the Windows NT system files.


1.10 Setup displays the "Your computer uses password protection"
     screen.
----------------------------------------------------------------
See section 1.12.

1.11 Setup displays the "Your computer is using an incompatible
     delete-protection program" screen.
---------------------------------------------------------------
See section 1.12.

1.12 Setup detects that your computer uses DR DOS.
--------------------------------------------------
If you have DR DOS installed on your computer, take the following
precautions before restarting Setup:

o If your system has any security features, including password protection,
  disable them. For more information, see "Setup displays the 'Your
  computer uses password protection' screen" in the chapter "Diagnosing
  and Solving Problems" in the MICROSOFT MS-DOS USER'S GUIDE.

  If you have protected any files or directories with a password,
  remove the password protection, particularly if you have protected
  your CONFIG.SYS or AUTOEXEC.BAT files, or your DR DOS directory.

o If you have DELWATCH installed on your computer, carry out
  the procedure "Setup displays the 'Your computer is using an
  incompatible delete-protection program' screen" in the chapter
  "Diagnosing and Solving Problems" in the MICROSOFT MS-DOS
  USER'S GUIDE.

o If your CONFIG.SYS or AUTOEXEC.BAT files use any conditional commands--
  such as the "?" or GOTO commands--remove them and adjust the order of
  commands in your startup files accordingly.

o If your CONFIG.SYS file uses the CHAIN command, remove it and
  adjust the order of commands in the file accordingly.

o If your computer uses disk compression, but drive C is not compressed,
  run Setup as described in the chapter "Getting Started" in the
  MICROSOFT MS-DOS USER'S GUIDE. When Setup displays the "Your
  CONFIG.SYS file contains commands that are not valid MS-DOS commands"
  message, choose the "Modify original files" option.

  If drive C is compressed, carry out the following procedure:

  1. Determine which drive is your original uncompressed drive. For more
     information, see your DR DOS documentation.

  2. Make backup copies of the CONFIG.SYS and AUTOEXEC.BAT files on your
     compressed drive, and the DCONFIG.SYS file on your uncompressed drive.

  3. Combine the two configuration files. For example, if drive D is your
     uncompressed drive, type the following at the command prompt:

     COPY D:\DCONFIG.SYS+C:\CONFIG.SYS D:\CONFIG.SYS

  4. Copy the combined CONFIG.SYS file to drive C. For example, if drive
     D is your uncompressed drive, type the following at the command
     prompt:

     COPY D:\CONFIG.SYS C:\CONFIG.SYS

  5. Copy your AUTOEXEC.BAT to your uncompressed drive. For example, if
     drive D is your uncompressed drive, type the following at the
     command prompt:

     COPY C:\AUTOEXEC.BAT D:\AUTOEXEC.BAT
    
  6. Run MS-DOS 6.22 Setup.

  7. When Setup displays the "Your CONFIG.SYS file contains commands
     that are not valid MS-DOS commands" message, choose the "Modify
     original files" option.

     When Setup displays the "Because you are currently using the
     DR DOS operating system" message, choose Continue.

  8. After Setup is complete, MS-DOS displays an "Unrecognized command"
     message on your screen for each command in your AUTOEXEC.BAT and
     CONFIG.SYS files that is not a valid MS-DOS command. Remove these
     commands from your CONFIG.SYS and AUTOEXEC.BAT files.

  9. Add the DEVICE=HIMEM.SYS command to the beginning of your
     CONFIG.SYS file, and the restart your computer.

1.13 Installing MS-DOS on a Drive Other Than C
----------------------------------------------
As described in the following procedure, you can install MS-DOS
on a drive other than C by using the /M switch to copy the system
files to your startup drive and then using the /Q switch to copy your
MS-DOS files to a different drive.

NOTE  This procedure is designed for advanced users. If your computer
uses disk-compression software, modify the procedure as appropriate.

NOTE  If your computer uses disk-partitioning software, such as Disk
Manager, SpeedStor, Priam, or Everex, do not carry out the procedure until
you have carried out steps 1 through 3 of "You need to install MS-DOS
manually" in the chapter "Diagnosing and Solving Problems" in the
MICROSOFT MS-DOS USER'S GUIDE. If your software uses a driver to
enable the drive on which you want to install MS-DOS, make sure you create
a startup disk with the driver in a CONFIG.SYS or AUTOEXEC.BAT file.
After you have carried out these steps, skip to step 3 of the following
procedure.

1. Run Setup by inserting Setup Disk 1 in drive A or B, and
   typing A:SETUP /M or B:SETUP /M at the command prompt.

   NOTE  Your CONFIG.SYS and AUTOEXEC.BAT files were saved as CONFIG.NEW
   and AUTOEXEC.NEW.

2. Run Setup by inserting Setup Disk 1 in drive A or B, and typing
   A:SETUP /Q or B:SETUP /Q at the command prompt. Follow the
   instructions on your screen.

3. When Setup displays the system settings screen, choose the MS-DOS
   Path option. Type the drive and directory where you want
   to install MS-DOS, and press ENTER. Continue Setup.

4. After Setup is complete, open your CONFIG.NEW and AUTOEXEC.NEW files
   and ensure that their commands specify the correct path. Save the files
   as CONFIG.SYS and AUTOEXEC.BAT. Then restart your computer.

1.14 Bypassing the Uninstall Disk and Using Default Setup Options
-----------------------------------------------------------------
To keep Setup from creating an Uninstall Disk, use the /G switch
with the Setup command.

To bypass the Uninstall disk and use default Setup options
instead of choosing them yourself, use both the /H and /G switches
with the Setup command.

WARNING  The primary purpose of the Uninstall disk is to safeguard
your files during and after Setup. If Setup doesn't create
an Uninstall disk, you will not be able to restore your previous
version of DOS. If Setup should render your hard disk inaccessible,
you will not be able to use the Uninstall disk to make it accessible
again.

IMPORTANT  If you have not created an Uninstall disk and Setup cannot
complete, do not try to use your computer except as directed by 
Microsoft Product Support Services. Otherwise, you could lose data.

NOTE  If you have a version of MS-DOS earlier than 5.0, and you plan
to use the /G switch or the /H and /G switches together, follow the
instructions in the NETWORKS.TXT file to update your network software
before running Setup.

1.15 Installing MS-DOS 6.22 on a System with a CorelSCSI UNI_ASP.SYS Driver
--------------------------------------------------------------------------
If your system uses the CorelSCSI UNI_ASP.SYS device driver for optical
drives, and Setup stops running when you try to install MS-DOS 6,
delete the DEVICE command in your CONFIG.SYS that loads the Corel
UNI_ASP.SYS driver. Then run Setup again. After Setup is complete,
reinstall the Corel UNI_ASP.SYS driver as you originally installed it.
If you continue to have problems, contact Corel Customer Service.

1.16  Installing MS-DOS 6.22 if you have DrivePro or EZ-Drive
------------------------------------------------------------
If Setup detects that your hard disk was set up using Micro House
DrivePro(tm) or EZ-Drive(tm), you must run the DOS6INST.EXE program
before you can safely install MS-DOS 6.22. The DOS6INST.EXE program
is provided on the Micro House diskette; it is also available on
the Micro House BBS at [phone]. For further assistance, 
contact Micro House Technical Support.

1.17 Setup displays the "There is not enough free disk space" screen
     and you are running PC-DOS version 6.1 with compression 
--------------------------------------------------------------------
If your computer is running PC-DOS version 6.1 with PC-DOS disk 
compression, when you run MS-DOS Setup, it displays the message 
"There is not enough free disk space on drive C to install MS-DOS." 

PC-DOS disk compression is incompatible with MS-DOS. Before you 
install MS-DOS 6.22, you must first uninstall your PC-DOS disk
compression from all your compressed drives and then completely
remove PC-DOS disk compression. For more information, see "Upgrading
from PC-DOS 6.1" later in this file.

Note: If you have completely uninstalled PC-DOS compression and this
      message still occurs, you also need to free some space on drive C.

1.18  Setup cannot update a file
--------------------------------
If Setup cannot update one of your MS-DOS files, it displays a message
with the title "Cannot Update File." If you continued Setup, your MS-DOS 
6.22 installation is incomplete because the specified file was not updated
to version 6.22. If the file is one you know you don't need (for example,
if it's a DoubleSpace file and you don't use DoubleSpace), don't worry 
about it. (If you are running PC-DOS 6.1, see section 1.20 of this file).
If you are not sure, update the file using the following procedure (you 
will need your MS-DOS 6.0 distribution disks):

1. If you use DoubleSpace and the file that was not updated was a 
   DoubleSpace file, or if your system does not work properly after 
   you receive this error message, insert your Uninstall disk in 
   drive A and type A:\UNINSTAL at the command prompt. 

2. Insert MS-DOS 6.0 Setup Disk 1 (not MS-DOS 6.22 Setup Disk 1) in 
   drive A or drive B, and then use MS-DOS Editor (EDIT) to view 
   the contents of the PACKING.LST file. This file tells you where each 
   file is located on your MS-DOS 6.0 disks. Determine which MS-DOS 6.0 disk 
   contains the file you need. 

3. Insert the appropriate MS-DOS 6 disk in drive A or drive B, and then
   use the EXPAND command to expand the file. For example, to expand the
   file DRVSPACE.BI_ from the disk in drive A to the directory C:\DOS, 
   you would type the following  command:
   
	EXPAND A:\DRVSPACE.BI_ C:\DOS\DRVSPACE.BIN

   For more information, see the comments at the beginning of the PACKING.LST
   file, or see the MS-DOS 6 User's Guide.

4. Run MS-DOS 6.22 Setup again. This time, Setup should be able to update the
   file. 
   
1.19 Upgrading from PC-DOS 6.1
------------------------------
If your computer is running PC-DOS version 6.1 with PC-DOS disk 
compression, you cannot install MS-DOS 6.22 until you remove the
disk compression. This is because PC-DOS disk compression is 
incompatible with MS-DOS. Follow these steps:

1. First, uninstall your PC-DOS disk compression from all your 
   compressed drives. (For information on uncompressing PC-DOS 
   compressed drives, see the information on the SSUNCOMP command 
   in the PC-DOS documentation.)
 
2. When SSUNCOMP uncompresses your last compressed drive, it asks
   if you want to disable the driver. Answer Yes to remove the
   PC-DOS version of the DRVSPACE.BIN file. 

3. Change to the directory that contains your PC-DOS files, and 
   then type the following command:

	DEL DRVSPACE.*
