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:  At the MS-DOS prompt, type edit config.sys, and then press ENTER. Find the Device= line that contains the ATAPI Real Mode CD-ROM driver. Edit the line so the /D: switch does not contain the word value cdrom. For example change the following line from

Device= /d:cdrom

to

Device= /d:test1

where  is the path and file name of your CD-ROM driver.

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