     dpt* at pci? dev ? function ?
     scsibus* at dpt?

DESCRIPTION    [Toc]    [Back]

           DPT SmartCache III
           DPT SmartCache IV
           DPT SmartRAID III
           DPT SmartRAID IV

DIAGNOSTICS    [Toc]    [Back]

     None  of  these  messages should be encountered under normal
     It should be noted that the list below is not complete.

     dpt0: readcfg failed - see dpt(4)   The  EATA  configuration
data did not
     appear  upon request.  This may be caused by older firmware.
     the solution is to power-cycle the affected machine.

     dpt0: spurious intr  A spurious interrupt was received  from
the HBA.

     dpt0:  bogus status (returned CCB id NNNN)  A corrupt or incomplete status
     packet was received from the HBA.

HISTORY    [Toc]    [Back]

     This manpage is inadequate.

     The dpt driver first appeared in OpenBSD 2.5.

AUTHORS    [Toc]    [Back]

     The  dpt  driver  was written by Andy Doran <ad@netbsd.org>,
based upon the
     uha and bha drivers, which are the work of others.

BUGS    [Toc]    [Back]

     The first (0th) and subsequent (for multi-channel cards) scsibus(4)
     should be attached at the dpt, because of the way the driver
is written
     and OpenBSD scsi(4) layer design limitations.

     EATA adapters other than listed may function correctly  with
the dpt driver,
 however a definitive list is not available.

     Older  firmware  may  prove  problematic.  It is recommended
that the latest
     available firmware be used.  Contact DPT for a firmware  update.

     Older  boards  that do not support scatter-gather I/O or DMA
are not supported.

     An ISA front-end is needed.

     ECC formatted disk and arrays (i.e., with a sector  size  of
528 bytes) do
     not  work correctly with the PM2041 and certain firmware revisions of the
