Installing and onfiguring SCSI drivers

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.
