When DMA Bus-Mastering is enabled for the EIDE bus, Windows NT may crashwith a STOP 0x0000000A in Atapi.sys when it accesses specific IDE-basedCD-ROM drive.
Instead of a STOP 0x0000000A message being displayed, a CD-ROM drive mightbe "unrecognized."
The Atapi.sys driver does not correctly handle the SCSIOP_READ_CD internalcommand sent by higher-level drivers.
To avoid this problem, perform one of the following below:
Disable DMA Bus-Mastering.
Switch to a SCSI-based CD-ROM drive.
