In /boot/device.hints:

For most PC-9801-55, -92 and compatibles: hint.ct.0.at=isa

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

For TEXA adapters: 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 driver provides access to the SCSI bus connected to a WD33C93[ABC] based host adapter.

HARDWARE

The 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 driver. The network device name for ctau(4) is ``ct '' Please see ctau(4) for the details for that device.

HISTORY

The device driver has been developed for Nx Ns /pc98 and ported for Fx . It first appeared in Fx 4.4 .

AUTHORS

The driver was written by An Naofumi HONDA .
