Computer hangs when CD-ROM is not in drive due to data transfer rate.
Cause:
Early versions of the NEC 4X CD-ROM drive have a problem with synchronous data transfer on some SCSI host adapters. This problem may also occur with some NEC 3Xi and 3Xe CD-ROM drives.
Solution:
Clear the 'Auto Insert Notification' and 'Sync Data' check boxes in Device Manager.
1) Click the 'Start' button to display the 'Start' menu.
2) Select 'Settings' and select 'Control Panel'. (The 'Control Panel' window appears.)
3) Double-click the 'System' icon. (The 'System Properties' dialog box appears.)

4) Click the 'Device Manager' tab, and double-click 'CDROM'.
5) Double-click the CD-ROM drive to be reconfigured.
6) Click the 'Settings' tab, and clear the 'Auto insert notification' and 'Sync data transfer' check boxes.

7) Click 'OK'.
8) Click 'OK' again to close the 'System Properties' dialog box. (The 'System Settings Change' dialog box appears.)
9) Click 'Yes' to restart the computer.

NOTE 1: If the problem persists, try disabling synchronous data transfer on the SCSI host adapter. (For information about disabling synchronous data transfer on the SCSI host adapter, refer to the documentation included with the adapter.)
NOTE 2: If these steps do not succeed in resolving the problem, contact the manufacturer to inquire about obtaining a firmware upgrade for the CD-ROM drive.
