ATAPI CD-ROM Drive Not Accessible with PCMCIA Devices
ID: Q133184
|
The information in this article applies to:
-
Microsoft Windows NT Workstation version 3.51
-
Microsoft Windows NT Server version 3.51
SYMPTOMS
After you upgrade or install Windows NT 3.51 on a laptop computer with
two enhanced IDE (EIDE) controllers and an ATAPI-compatible CD-ROM drive,
the following system event appears in the Event Viewer:
Event: 9
Source: ATAPI
Type: Error
Description: The device \Device\ScsiPort0 - did not respond within the timeout period.
The CD-ROM icon is not available in File Manager.
CAUSE
This problem occurs when the secondary EIDE controller (used for the CD-
ROM) and a PCMCIA card are configured with the same IRQ.
Some PCMCIA cards (type I, II, or III) are shipped with the IRQ configured
for IRQ 15. Some EIDE controllers, by default, are also set to IRQ 15.
RESOLUTION
To correct this problem:
- Verify that the CD-ROM drive operates:
- Remove all drivers for the PCMCIA cards.
- Turn off your computer and remove all PCMCIA cards.
- Restart Windows NT and verify that the CD-ROM drive icon appears
in File Manager. If the CD-ROM drive icon does not appear in
File Manager, contact your CD-ROM drive manufacturer.
- If you have already installed the drivers for the PCMCIA cards,
change the IRQ to another unused IRQ. If not, install the driver
for an unused IRQ.
- Turn off your computer and insert all PCMCIA cards.
- Restart Windows NT.
