-.Sh NAME
-.Nm ncv
-.Nd "NCR 53C500 based SCSI host adapter driver"
-.Sh SYNOPSIS
-To compile this driver into the kernel,
-place the following lines in your
-kernel configuration file:
-.Bd -ragged -offset indent
-.Cd "device scbus"
-.Cd "device ncv"
-.Ed
-.Pp
-Alternatively, to load the driver as a
-module at boot time, place the following line in
-.Xr loader.conf 5 :
-.Bd -literal -offset indent
-ncv_load="YES"
-.Ed
-.Sh DESCRIPTION
-The
-.Nm
-driver provides access to the
-.Tn SCSI
-bus
-connected to an NCR 53C500 based
-PC-Card
-.Tn SCSI
-host adapter or an Adaptec AHA-2920 on the
-.Tn PCI
-bus.
-.Sh HARDWARE
-The following devices are currently supported by the
-.Nm
-driver:
-.Pp
-.Bl -bullet -compact
-.It
-I-O DATA PCSC-DV
-.It
-KME KXLC002 (TAXAN ICD-400PN, etc.), KXLC004, and UJDCD450
-.It
-Macnica Miracle SCSI-II mPS110
-.It
-Media Intelligent MSC-110, MSC-200
-.It
-New Media Corporation BASICS SCSI
-.It
-Qlogic Fast SCSI
-.It
-RATOC REX-9530, REX-5572 (SCSI only)
-.El
-.Sh DIAGNOSTICS
-The following error messages are sometimes returned:
-.Bl -diag
-.It "SCSI BUS RESET failed"
-Usually returned when a failure occurs during
-the bus reset.
-.It "CMD_NOP failed"
-No operation or the operation has failed.
-.It "CMD_NOP|CMD_DMA"
-A failure occurred during the
-.Tn DMA
-read/write operations.
-.El
-.Pp
-The
-.Nm
-driver should return
-.Bq Er ENODEV
-when any of the previously noted failures occur.
-.Sh SEE ALSO
-.Xr cardbus 4 ,
-.Xr cd 4 ,
-.Xr da 4 ,
-.Xr pccard 4 ,
-.Xr sa 4 ,
-.Xr scsi 4
-.Sh HISTORY
-The
-.Nm
-device driver has been developed for
-.Nx Ns / Ns Tn pc98
-and ported to
-.Fx .
-The
-.Nm
-driver first appeared in
-.Fx 2.2
-with
-.Tn PAO
-and merged in
-.Fx 4.2 .
-.Sh AUTHORS
-.An -nosplit
-The
-.Nm
-driver was written by
-.An Naofumi Honda .
