This article was previously published under Q134709 SYMPTOMS
When you are using a single-speed CD-ROM drive that is connected to a SCSI
controller, video performance in CD-ROM-based programs may be poor. This
poor performance may be more pronounced on computers with slower
processors. Performance in these programs may appear to be worse than it
is in earlier versions of Windows.
This problem is known to occur with the following SCSI controllers:
CAUSE
The Windows 95 protected-mode CD-ROM drivers are not completely compatible
with single-speed CD-ROM drives.
RESOLUTION
To work around this problem, use one of the following methods:
- Contact the hardware manufacturer to inquire about protected-mode
drivers for your CD-ROM drive for use with Windows 95.
- You may be able to improve performance somewhat by disabling the
Windows 95 protected-mode drivers for your CD-ROM drive, and using
the real-mode drivers that came with the drive instead. For
information on how to do so, contact the hardware manufacturer.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Windows 95. We
are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
