     kernel configuration file:

	   device scbus
	   device ncv

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   ncv_load="YES"

DESCRIPTION
     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.

HARDWARE
     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)
