RBF supports a wide range of devices having different performance and storage capacities. Consequently, it is highly parameter driven. The physical parameters it uses are stored on the media itself. On disk systems, this information is written on the first sector of track number 0. The device drivers also use the physical parameters stored on sector 0. These parameters are written by the format program that initializes and tests the media. OS-9 Porting Guide 223
