Ena bling E/ISA I/O Por ts On HP 700 SystemsThe process for making the E/ISA I/O ports on HP 700 platforms involves a few steps.Aconfig file for the HP eisa_config utility is required, such as the following, which isappropriate for the Oregon Micro Systems PC boards:BOARDID = "OMS0001"NAME = "OMS PCX/PC38 Motor Controllers"MFR = "Oregon Micro Systems"CATEGORY = "OTH"SLOT = ISA8IOCHECK = INVALIDDISABLE = UNSUPPORTEDFUNCTION = "I/O Registers"TYPE="OTH"CHOICE="default"LINKPORT = 330hSIZE = BYTESHARE = NOLINKPORT = 331hSIZE = BYTESHARE = NOLINKPORT = 332hSIZE = BYTESHARE = NOLINKPORT = 333hSIZE = BYTESHARE = NOAsimilar file needs to be created for each ISA card you intend to use with spec andplaced in the directory /etc/eisa with a name that matches the board ID, as in!OMS0001.CFG for ID = "OMS0001" . The IDs are arbitrary for ISA boards. Be sureto enter the PORT addresses for all the I/O ports to be used on the card.After the configuration files are installed, you must run the HP eisa_config utility tosave the configuration. Youmust also reboot the computer to make the boards available.When spec starts up, it will use the CSS hp_ports utility to create a special file thatwill be used to access the ports. For example, the special file /dev/ioports/0x330 willbe created to access the ports described in the example above. spec will create onespecial file for each eight consecutive I/O ports.INTERIM WORK-IN-PROGRESS (8/16/01) NOT FOR GENERAL DISTRIBUTION ADMINISTRATOR’S GUIDE 201
