SYMPTOMS
When you use DMA Bus-Mastering on a PCI IDE controller using Atapi.sys
(Service Pack 2 or later) you may experience the following blue screen
error message:
NOTE: The first parameter will vary and the fourth parameter will always fall in the range of Atapi.sys. CAUSEThis is caused when the buffer provided to Atapi is in user-mode and the driver not running in the same context, accesses the buffer. This happens specifically with the inquiry command using pass-through-direct mode. WORKAROUND
Disable DMA Bus-Mastering for Atapi or contact the manufacture of the
application for an update or rewrite the application to use
IOCTL_SCSI_PASS_THROUGH.
MORE INFORMATIONThis is a design problem that has been seen with applications that use the SCSIOP_INQUIRY commands to the miniport through the IOCTL_SCSI_PASS_THROUGH_DIRECT interface. In order to send IOCTL_SCSI_PASS_THROUGH_DIRECT you must be an administrator. This IOCTL should not be used to send a SCSIOP_INQUIRY.
