NAME

     ct -- WD33C93[ABC] based CBUS SCSI host adapter driver

SYNOPSIS

     device ct
     device scbus

     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 I-O DATA SC98 adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x10000"

     For LOGITEC adapters:
     hint.ct.0.at="isa"
     hint.ct.0.flags="0x50000"

     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 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

     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>.

NAME

     aha -- Adaptec SCSI host adapter driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in your kernel configuration file:

	   device scbus
	   device aha

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   aha_load="YES"

     In /boot/device.hints:
     hint.aha.0.at="isa"

DESCRIPTION

     This driver provides access to the SCSI bus connected to the Adaptec AHA-154x and AHA-1640 SCSI host adapters.  x is 0 for controllers with-
     out a floppy drive and 2 for controllers that have them.  For optimum performance, Adaptec AHA-174x controllers should be configured in
     enhanced mode and attached via the ahb(4) driver.

     One device hint entry for every card to be attached by the system is required.  Specific values for the port address, IRQ, and DRQ may be
     specified.  If wildcard values are used, the driver will query the device for its current settings and use those.	If the port address is a
     wildcard, the driver consults an internal table of possible port address locations and attaches to the first unattached card it finds.  The
     possible port addresses for this card are 0x330, 0x334, 0x230, 0x234, 0x130, and 0x134.

     The AHA-1640 is an MCA bus card.  Since the MCA bus is a self-identifying bus, no setting of hints is required.

HARDWARE

     The aha driver supports the following SCSI host adapters:

     o	 Adaptec AHA-154xB
     o	 Adaptec AHA-154xC
     o	 Adaptec AHA-154xCF
     o	 Adaptec AHA-154xCP
     o	 Adaptec AHA-1640
     o	 Adaptec AHA-174x in 154x emulation mode
     o	 DTC 3290 SCSI controller in 1542 emulation mode
     o	 Tekram SCSI controllers in 154x emulation mode

SEE ALSO

     ahb(4), ahc(4), aic(4), cd(4), da(4), sa(4), scsi(4)

AUTHORS

     The aha driver was ported by M. Warner Losh from the bt driver written by Justin T. Gibbs.

BUGS

     The AHA-154xA card does not support residuals on data transfers.  As a result, this card is no longer supported.

     There have been some reports that the AHA-154xB does not work well under heavy load.

     The AHA-154xCP is a plug and play controller.  However, its resources are set using the on-board BIOS and cannot be moved.  Failures to
     attached for this card are often caused when the resources set in the BIOS conflict.
