This article was previously published under Q136955 SYMPTOMS
If you eject an audio CD from a Panasonic CR-562B CD-ROM drive while it is
playing, your computer may stop responding (hang).
CAUSE
The Panasonic CR-562B CD-ROM drive is not completely compatible with the
Windows 95 protected-mode disk drivers.
RESOLUTION
To work around this problem, load the real-mode drivers for the CD-ROM
drive in the Config.sys and Autoexec.bat files. For information about the
parameters for the real-mode driver and Mscdex.exe, please refer to the
drive's documentation or manufacturer.
If loading the real-mode drivers for the CD-ROM drive does not resolve the
problem, disable the protected-mode driver for the CD-ROM controller in
Device Manager. To do so, follow these steps:
- In Control Panel, double-click the System icon.
- On the Device Manager tab, double-click the CD-ROM Controllers branch
of the hardware tree to expand it.
- Click MKEPanasonic CD-ROM Drive, and then click Properties.
- Click the Original Configuration (Current) check box to clear it, and
then click OK.
You may want to contact the drive's manufacturer to inquire about a
possible firmware upgrade that corrects this problem.
MORE INFORMATION
The Panasonic CR-562B CD-ROM drive uses a proprietary interface and
controller. The real-mode CD-ROM driver that is loaded in the Config.sys
file for this drive varies, depending on the exact version of the Panasonic
CD-ROM drive controller being used. If the real-mode CD-ROM driver being
used is a driver that Windows 95 has determined it can safely take over,
the Windows 95 protected-mode driver for Panasonic CD-ROM controllers is
loaded. When this driver is loaded, the problem described in this article
may occur.
