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:

Stop 0x0000000A (0x00830830, 0x0000000d, 0x00000001 0x800059f0)
Address 800059f0 has base at 80005000 - ATAPI.SYS

NOTE: The first parameter will vary and the fourth parameter will always fall in the range of Atapi.sys.


This 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.


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.

For more information on DMA Bus-Mastering, please refer to the following Microsoft Knowledge Base article:

TITLE : How to Enable IDE DMA Bus-Mastering using SP2 ATAPI.SYS


This 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.
