386/486 CBUS SCSI host adapter device driver
This driver is no longer supported by SCO,
however, it is still provided with SCO OpenServer
for your convenience. Contact your hardware
vendor for support.
ciha is the device driver for
386/486 CBUS SCSI host adapter cards.
Refer to the
Compatible Hardware Web Pages.
to determine the support status of your host adapter, or
contact your system supplier.
Configuring the ciha driver
You can configure the ciha driver using entries in
/etc/conf/cf.d/mdevice and /etc/conf/sdevice.d/ciha.
Changes to these files
take effect once you relink the kernel using
and reboot the system.
Configure ciha driver-specific characteristics
by editing the /etc/conf/pack.d/ciha/space.c file,
which controls parameters such as the SCSI ID,
parity checking, timeouts, and negotiation options.
Boot time configuration of SCSI
parameters to override
the default hardware configuration information.
Of special interest are the adapter= parameter
that specifies information for
the host adapter card
that plugs into or is part of the motherboard,
and the periph= parameter
that specifies information about the host adapter
being used by one of the generic peripheral interfaces
(Sdsk, Srom, or Stp).
The ciha driver
supports all standard SCSI ioctls
that are defined in the <sys/scsicmd.h> header file
and documented on the
for general information about kernel error messages,
including a list of generic device driver errors.
