ID: Q229895

The information in this article applies to:
  • Microsoft Windows NT Workstation version 4.0
  • Microsoft Windows NT Server version 4.0
  • Microsoft Windows NT Server, Enterprise Edition version 4.0

SYMPTOMS

When you start an unattended installation of Windows NT 4.0 from an MS-DOS prompt, you may receive the following error message:

Setup was unable to copy the following file, cdrom.sys.
Also, in MS-DOS mode you may not be able to create or manipulate any file called Cdrom.sys.


CAUSE

This problem can occur if you load ATAPI Real Mode CD-ROM driver in the Config.sys file.


RESOLUTION

To resolve this problem, edit the Config.sys file. To do this, follow these steps:

  1. At the MS-DOS prompt, type edit config.sys, and then press ENTER.


  2. Find the Device= line that contains the ATAPI Real Mode CD-ROM driver.


  3. Edit the line so the /D: switch does not contain the word value cdrom.


    4. For example change the following line from
    Device=<driver> /d:cdrom
    to
    Device=<driver> /d:test1
    where <driver> is the path and file name of your CD-ROM driver.

Additional query words: msdos cdrom.sys cdrom unattend install nt 4.0
