MORE INFORMATION

Turning on the Real Mode CD-ROM Drive Drivers

Turning on the real mode drivers for your CD-ROM drive allows you to install Office while Windows is running in Safe Mode.

Use one of the following methods to turn on the real mode drivers for your CD-ROM drive:

Method 1: Use the Windows 98 Startup Disk

Windows 98 contains a utility for creating a startup disk to troubleshoot Windows if Windows does not start. The startup disk includes real mode drivers for the most commonly used CD-ROM drives. Follow these steps to create a startup disk:

1. On the Start menu, point to Settings and then click Control Panel.
2. Double-click Add/Remove Programs. Click the Startup Disk tab.
3. Insert a formatted floppy disk into your A drive.
   
   NOTE: Any existing files on the floppy disk will be deleted.
4. Click OK in the Insert Disk dialog box.
   
   The necessary files are copied to the A drive. Click OK to close the Add/Remove Programs Properties dialog box.
   
   NOTE: If your hard disk is formatted with the FAT32 file system, you need to follow the directions in the following Microsoft Knowledge Base article to create a Startup disk that is compatible with your computer:

You need to add a line to the Config.sys file to allow Windows to start in Safe Mode. To do this, follow these steps:

1. On the Start menu, click Run. Type the following in the Open box and then press ENTER:

   Notepad a:\config.sys

2. Type the following line at the end of the Config.sys file:

   Device=<drive>:<path>\ifshlp.sys

   Where <drive> and <path> specify the location of your Windows directory. For example, if your Windows directory is on drive C and is named WINDOWS, you type the following:

   Device=C:\WINDOWS\ifshlp.sys

3. Click Save on the File menu.
4. Click Exit on the File menu.

Follow these steps to start your computer in Safe Mode using the Windows 98 Startup disk.

1. Insert the Windows 98 Startup disk into your A drive.
2. Restart your computer.
3. Press ENTER when the Windows 98 Startup menu appears.
4. Type the following command at the command prompt, and then press ENTER:

   c:

5. Type the following command at the command prompt, and then press ENTER:

   cd\windows

6. Type the following command at the command prompt, and then press ENTER:

   win /d:m

   NOTE: If you are attempting to perform an administrative installation (setup /a) of Microsoft Office to a network server and you need to start Windows in Safe Mode with both CD-ROM drive and network support, type the following command instead:

   win /d:n

7. Click OK in the alert that indicates that Windows is running in Safe Mode.

Now that Windows is in Safe Mode, you need to determine whether the real mode CD-ROM drivers located in the Windows 98 Startup disk are compatible with your CD-ROM drive. To do this, double-click My Computer. If you see an icon for your CD-ROM drive, insert your Microsoft Office CD and try running Setup.

If you do not see an icon for your CD-ROM drive in the My Computer window, proceed to "Method 2: If the Config.sys File Is Present on Drive C".

Method 2: If the Config.sys File Is Present on Drive C

If the CD-ROM drivers on the Windows 98 Startup disk are not compatible with your CD-ROM drive, you can check your Config.sys file to see whether compatible drivers are located on your system. To do this, follow these steps:

1. Click Start, point to Programs, point to Accessories, point to System Tools, and then click System Information.
   
   Microsoft System Information is started.
2. Click System Configuration Utility on the Tools menu.
   
   The System Configuration Utility is started.
3. Click the Config.sys tab.
   
   This step displays the contents of the Config.sys file. If no text is visible in the window, proceed to "Method 3: If No Config.sys File Is Present on the C Drive".
4. Locate the line that loads the real mode CD-ROM drive driver.
   
   NOTE: This line contains the following:

   device=

   -and-

   /d:<cd rom drive device id>

   For example, the line in Config.sys for your CD-ROM driver may look similar to the following:

   device=c:\cdrom\cdromdrv.sys /d:MSCD001

5. Write down the drive identifier string after "/d:" in the Config.sys window. You need this information later. An example of this identifier is MSCD001.
6. If the "device=" line is remarked (starts with "rem"), remove the word "rem." To do this, follow these steps:
   1. Click to select the "device=" line.
   2. Click Edit.
   3. Remove "rem " from the beginning of the line, and then press ENTER.
   NOTE: Do not leave a blank space at the beginning of the line.
7. Click Close on the File menu. Click Yes when you are prompted to save changes.
8. Click the Autoexec.bat tab.
9. Look for a line that is similar to the following:

   c:\windows\command\mscdex.exe /d: mscd001 /s

   If you do not see a line similar to this, you need to add a line to load the Mscdex extensions for your CD-ROM. To do this, follow these steps:
   1. Click New.
   2. Type the following line, and then press ENTER:

      <drive>:<path>\command\mscdex.exe /d:<CD-ROM Device Id>

      where <drive> and <path> specify the location of your Windows directory, and <CD-ROM Device Id> is the drive identifier for your CD-ROM drive that you noted in Step 5.
      
      For example, if your Windows directory is on drive C and is named windows and your CD-ROM drive is mscd001, type the following:

      c:\windows\command\mscdex.exe /d: mscd001

10. Click OK. Click No when you are prompted to restart your computer. Go to the "Restarting Windows 98 in Safe Mode Using Step-by-Step Confirmation" section of this article.
