DDI information

UnixWare 7 drivers based on DDI 8 for ISA adapters must use the CFG_VERIFY subfuntion to the config( ) entry point routine. DDI 7 drivers that support ISA bus devices must use the _verify( ) entry point routine. These routines validate the existance of the hardware and verifies the configuration information. This can be done in a variety of ways. For example, in HBA drivers, it can find almost all the necessary configuration information in the hba_idata_v5(D4sdi) structure and verifies the existance of the hardware. Other device types access parameters such as CM_IOADDR, documented on the cm_params(D5) manual page. See the HDK sample drivers for detailed information about how to code the verification routine for the type of device being supported.

For additional information about autoconfiguring UnixWare 7 MDI ISA bus drivers see the following:

For information about the special considerations involved in configuring a driver that supports both ISA bus devices and smartbus devices such as PCI, EISA, and MCA, see ``Drivers that support ISA and another bus type''.
