ncv -- NCR 53C500 based SCSI host adapter driver
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 devices are currently supported by the ncv driver:
o I-O DATA PCSC-DV
o KME KXLC002 (TAXAN ICD-400PN, etc.), KXLC004, and UJDCD450
o Macnica Miracle SCSI-II mPS110
o Media Intelligent MSC-110, MSC-200
o NEC PC-9801N-J03R
o New Media Corporation BASICS SCSI
o Qlogic Fast SCSI
o RATOC REX-9530, REX-5572 (SCSI only)
The following error messages are sometimes returned:
SCSI BUS RESET failed Usually returned when a failure occurs during the
CMD_NOP failed 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
cardbus(4), cd(4), da(4), pccard(4), sa(4), scsi(4)
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.
The ncv driver was written by Naofumi Honda. This manual page was writ-
