Installing and onfiguring SCSI drivers
This chapter supplements the information in
``Linking and testing SCO OpenServer 5 drivers''
and
``Packaging SCO OpenServer 5 drivers for installation''
with special information that applies to
SCSI peripheral
and SCSI host adapter drivers.
SCSI peripheral drivers-
are compiled and linked
like other drivers,
but must also have an entry in the
mscsi(F)
file.
SCSI host adapter drivers-
are configured into the kernel
like any other device driver,
except that they do not require
the normal device driver entry points
other than
init(D2osdi),
intr(D2osdi),
and possibly
halt( ).
The primary entry point to the driver is the
_entry( )
routine,
which is called by peripheral drivers
to send commands to SCSI peripheral devices
that are attached to that adapter.
The sample SCSI driver code
that is provided on the HDK
includes sample packaging and install scripts
that can be copied and modified for other drivers.
