compatibles), ICM IF-2660, Midori-Denshi MDC-554NA, or
0x10000 DMA transfer mode for an I-O DATA SC-98II
0x20000 bus-master transfer mode for a TEXA HA-55BS2, its
successors, or Midori-Denshi MDC-926R
0x30000 bus-master transfer mode for an ELECOM bus-master SCSI
0x40000 SMIT transfer mode (for supported adapters only)

ICM IF-2766, IF-2766ET, IF-2767 or IF-2769
The ct driver provides access to the SCSI bus connected to a WD33C93[ABC]
based host adapter.
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

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.
The ct device driver has been developed for NetBSD/pc98 and ported for
FreeBSD. It first appeared in FreeBSD 4.4.
The ct driver was written by Naofumi HONDA.
