NAME
osiop -- Symbios/NCR 53C710 SCSI driver SYNOPSIS
arc osiop* at jazzio? flags 0x00000 ews4800mips osiop* at sbdio? flags 0x00000 hp700 osiop0 at gsc? flags 0x00000 mvme68k osiop0 at pcctwo? ipl 2 scsibus* at osiop? DESCRIPTION
The osiop driver provides support for the Symbios/NCR 53C710 SCSI controller chip. For the Symbios/NCR 53C700 SCSI host adapters, use the oosiop(4) driver. For the Symbios/NCR 53C8xx PCI SCSI host adapters, use the siop(4) or esiop(4) driver. CONFIGURATION
The osiop driver supports the following flags for use in config(1) files: bits 0-7: disable disconnect/reselect for the corresponding SCSI target bits 8-15: disable synchronous negotiation for SCSI target bits 16: disable DMA interrupts "Target" is synonymous with SCSI ID number. Note that SCSI tape drives should be allowed to perform disconnect/reselect or performance will suffer. SEE ALSO

osiop driver first appeared in NetBSD 1.6. The original NCR 53C710 driver appeared in NetBSD 1.0 amiga port, and Izumi Tsutsui <tsutsui@NetBSD.org> modified the driver and made it machine-independent. BSD

The ct driver provides access to the SCSI bus connected to a WD33C93[ABC] based host adapter. HARDWARE
The ct driver supports the following adapters: o ELECOM bus-master SCSI adapters o I-O DATA SC-98II o ICM IF-2660, IF-2766, IF-2766ET, IF-2767 and IF-2769 o Logitec LHA-N151 and LHA-20x series o Midori-Denshi MDC-554NA and MDC-926R o NEC PC-9801-55, 92 and compatibles o SMIT transfer type SCSI host adapters o TEXA HA-55BS2 and its later models SEE ALSO
cd(4), ch(4), ctau(4), da(4), intro(4), sa(4), scsi(4) NOTES
Historically, the driver for the Cronyx Tau WAN adapters was ``ct''. This device name was changed to ``ctau'' to avoid conflicts with this pc98 ct driver. The network device name for ctau(4) is ``ct''. Please see ctau(4) for the details for that device. HISTORY
The ct device driver has been developed for NetBSD/pc98 and ported for FreeBSD. It first appeared in FreeBSD 4.4. AUTHORS
The ct driver was written by Naofumi HONDA. This manual page was written by Noriaki MITSUNAGA <non@FreeBSD.org> and Hideyuki KURASHINA <rushani@FreeBSD.org>. BSD
