.Dd November 18, 2003 .Dt NCV 4 .Os .Sh NAME .Nm ncv .Nd "NCR 53C500 based SCSI host adapter driver" .Sh SYNOPSIS .Cd "device ncv" .Cd "device scbus" .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.
p The following list of devices are currently supported:
p l -item -compact t IO DATA PCSC-DV t KME KXLC002 (TAXAN ICD-400PN, etc.), KXLC004, and UJDCD450 t Macnica Miracle SCSI-II mPS110 t Media Intelligent MSC-110, MSC-200 t NEC PC-9801N-J03R t New Media Corporation BASICS SCSI t Qlogic Fast SCSI t RATOC REX-9530, REX-5572 (SCSI only) .El .Sh DIAGNOSTICS The following error messages are sometimes returned: l -diag t SCSI BUS RESET failed
p Usually returned when a failure occurs during the bus reset. t CMD_NOP failed
p No operation or the operation has failed. t CMD_NOP|CMD_DMA
p A failure occurred during the .Tn DMA read/write operations. .El
p The .Nm driver should return q Er ENODEV when any of the previously noted failures occur. .Sh SEE ALSO .Xr cardbus , .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 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 The .Nm driver was written by .An Naofumi Honda .
