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. .El .Sh SEE ALSO .Xr intro 4 , .Xr cd 4 , .Xr ch 4 , .Xr scsi 4 . .Xr sd 4 , .Xr st 4 .Sh AUTHORS 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 .Ox 2.5 . .Sh BUGS This manpage is inadequate. .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.
