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:
- Future Domain TMC-850
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.
