STOP 0x0000000A or Difficulty Recognizing IDE CD-ROM Drives

• Microsoft Windows NT Workstation version 4.0
• Microsoft Windows NT Server version 4.0

SYMPTOMS

When DMA Bus-Mastering is enabled for the EIDE bus, Windows NT may crash with a STOP 0x0000000A in Atapi.sys when it accesses specific IDE-based CD-ROM drive.

-or-

Instead of a STOP 0x0000000A message being displayed, a CD-ROM drive might be "unrecognized."

CAUSE

The Atapi.sys driver does not correctly handle the SCSIOP_READ_CD internal command sent by higher-level drivers.

RESOLUTION

To avoid this problem, perform one of the following below:

• Disable DMA Bus-Mastering.
• Switch to a SCSI-based CD-ROM drive.
• Obtain the fixed Atapi.sys file referenced below.

  This fix should have the following timestamp:

        11/13/97  11:41a                26,448 Atapi.sys  (Intel)
        11/13/97  11:39a                60,272 Atapi.sys  (Alpha)
