hint.ct.0.at="isa"
For ELECOM bus-master SCSI adapters:
hint.ct.0.at="isa"
hint.ct.0.flags="0x30000"

hint.ct.0.at="isa"
hint.ct.0.flags="0x20000"
For adapters with SMIT transfer mode to enable SMIT transfer:
hint.ct.0.at="isa"
hint.ct.0.flags="0x40000"
hint.ct.0.maddr="0xdc000"
Flags meaning:
0x00000 DMA transfer mode for an NEC PC-9801-55, -92 (or compatibles), ICM IF-2660, Midori-Denshi MDC-554NA, or Logitec LHA-N151
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 adapter
0x40000 SMIT transfer mode (for supported adapters only)
0x50000 bus-master transfer mode for a Logitec LHA-20x series, ICM IF-2766, IF-2766ET, IF-2767 or IF-2769
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:
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

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.
