DESCRIPTION
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:
- ELECOM bus-master SCSI adapters
- I-O DATA SC-98II
- ICM IF-2660, IF-2766, IF-2766ET, IF-2767 and IF-2769
- Logitec LHA-N151 and LHA-20x series
- Midori-Denshi MDC-554NA and MDC-926R
- NEC PC-9801-55, 92 and compatibles
- SMIT transfer type SCSI host adapters
- TEXA HA-55BS2 and its later models
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
