Figure 1  Device Configuration Assistant - Major Data Structures

Figure 1 shows an example of the relationship between major data structures. A board structure is the central data structure in the system. Each board structure contains a pointer to a device database entry. When a BEF is loaded, the boot devices (represented by bef_dev structures) have pointers back to the controller. Finally each bef_dev structure has both a copy of the bdev_info structure supplied by the BEF, and if the BEF is still resident, a pointer to the actual bdev_info structure embedded in the BEF.
