ISA Device Auto Configuration

ISA Device Auto Configuration A key advantage of Berkeley UNIX is its ability to configure at boot time devices present on the system. This feature, while difficult to implement on the ISA given numerous conflicts, was considered valuable and was implemented. In Figure 10(a), we have data structures that encode all the appropriate information to configure a device in 386BSD. Each driver, which may have many devices, is able to locate and configure a device if present. The isa_device structure also contains the characteristics of each device to be recognized. If found, hardware resources can then be assigned to each device as configured. A sample table of possible devices to search for within the kernel appears in Figure 10(b).
