+.Sh SYNOPSIS
+.Cd "dpt* at eisa? slot ?"
+.Cd "dpt* at pci? dev ? function ?"
+.Cd "scsibus* at dpt?"
+.Sh HARDWARE
+The
+.Nm
+driver provides support for the following
+.Tn SCSI
+adapters:
+.Pp
+.Bl -tag -width -offset indent -compact
+.It Tn DPT SmartCache III
+.It Tn DPT SmartCache IV

+.Sh DIAGNOSTICS
+None of these messages should be encountered under normal circumstances. It
+should be noted that the list below is not complete.
+.Pp
+.Bl -tag -width indent 
+.It dpt0: readcfg failed - see dpt(4)
+.br
+The EATA configuration data did not appear upon request. This may be caused
+by older firmware. Generally the solution is to power-cycle the affected
+machine.
+.br
+.It dpt0: spurious intr
+.br
+A spurious interrupt was recieved from the HBA.
+.br
+.It dpt0: bogus status (returned CCB id NNNN)
+.br
+A corrupt or incomplete status packet was recieved from the HBA.

+.Sh AUTHOR
+The
+.Nm
+driver was written by 
+.An Andy Doran Aq ad@netbsd.org , 
+based upon the 
+.Nm uha
+and
+.Nm bha
+drivers, which are the work of others.
+.Sh HISTORY
+The
+.Nm dpt
+driver first appeared in
+.Nx 1.4.2 .
+.Sh BUGS
+This manpage is inadaquate.
+.Pp
+EATA adapters other than listed may function correctly with the
+.Nm 
+driver, however a definitive list is not avaiable.
+.Pp
+Older firmware may prove problematic. It is recommended that the latest
+available firmware be used. Contact DPT for a firmware update.
+.Pp
+Older boards that do not suppport scatter-gather I/O or DMA are not supported.
+.Pp
+An ISA front-end is needed.
+.Pp
+ECC formatted disk and arrays (i.e. with a sector size of 528 bytes) do not
+work correctly with the PM2041 and certian firmware revisions of the PM3334.
