Setup Hangs Accessing CD-ROM Drive with CD17F14A.SYS

ID: Q131748

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you are installing Windows 95 over an existing version of Windows or Windows for Workgroups version 3.x on an AT&T Globalyst model 515 or 590 computer, the computer may stop responding (hang) when Setup accesses the CD-ROM drive.

This problem is known to occur with the NEC CDR-260 CD-ROM drive with the Oak CD17F14A.SYS CD-ROM driver version 1.7_F14A.

CAUSE

The CD17F14A.SYS driver uses INT14h to access the CD-ROM drive, which also causes a problem in Windows and Windows for Workgroups 3.x. This problem occurs when you access the CD-ROM drive in File Manager in Windows or Windows for Workgroups 3.x as well, and is not a problem with Windows 95 Setup.

RESOLUTION

To work around the problem, restart your computer and install Windows 95 from an MS-DOS command prompt. If Windows 3.x starts automatically when you start your computer, quit Windows 3.x before you install Windows 95.
