SVR5 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 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''.
