ncv — NCR 53C500 based SCSI host adapter driver

       The  ncv  driver  was  written  by  Naofumi  Honda.   This  manual  page  was  written  by   Tom   Rhodes
       <trhodes@FreeBSD.org> and Noriaki Mitsunaga <non@FreeBSD.org>.

Debian                                           August 10, 2004                                          NCV(4)

       The ncv driver provides access to the SCSI bus connected to an NCR 53C500 based PC-Card SCSI host adapter
       or an Adaptec AHA-2920 on the PCI bus.

       The following error messages are sometimes returned:

       SCSIBUSRESETfailed  Usually returned when a failure occurs during the bus reset.

       CMD_NOPfailed  No operation or the operation has failed.

       CMD_NOP|CMD_DMA  A failure occurred during the DMA read/write operations.

       The ncv driver should return [ENODEV] when any of the previously noted failures occur.

       The following devices are currently supported by the ncv driver:

       •   I-O DATA PCSC-DV
       •   KME KXLC002 (TAXAN ICD-400PN, etc.), KXLC004, and UJDCD450
       •   Macnica Miracle SCSI-II mPS110
       •   Media Intelligent MSC-110, MSC-200
       •   New Media Corporation BASICS SCSI
       •   Qlogic Fast SCSI
       •   RATOC REX-9530, REX-5572 (SCSI only)

       The  ncv  device  driver  has been developed for NetBSD/pc98 and ported to FreeBSD.  The ncv driver first
       appeared in FreeBSD 2.2 with PAO and merged in FreeBSD 4.2.
