An Adapter Option File (AOF) describes a class of network adapters that the driver supports. Identical adapters such as clones and adapters that are very similar should share a single AOF. Multiple AOFs are used if one driver supports multiple bus types (such as PCI and ISA) or if an ISA driver supports different sets of hardware parameters (I/O address ranges, or IRQs).
The following information describes the structure and content of an AOF file. Look at the AOF files in the sample drivers that are provided in the HDK O5ndsamp package for examples; it is much easier to modify one of these than it is to write an AOF from scratch.
AOFs use the OSF stanza file format. A general description of this format is:
Section_name: Attribute_name=Attribute_valueValues are assigned to attributes under sections in stanza files. A section name and all of the attributes and values under that section are called a ``section''. Section names always have a colon ( : ) after them to differentiate them from attributes. A particular attribute can be uniquely referenced by prefixing its name by the section in which the attribute is located. For example, ADAPTER:KEY refers to the KEY attribute in the ADAPTER section.Section1_name: # this is a comment Attribute1_name=Attribute1_value Attribute2_name=Attribute2_value Attribute3_name=Attribute3_value1,Attribute3_value2
