Writing Device Drivers

driver.conf Files

driver.conf files are required for devices that are not self-identifying. Entries in the driver.conf file specify possible device instances the driver will probe for existence. See scsi(4) and driver.conf(4). Driver global properties can also be set by entries in the driver.conf(4) file. driver.conf files are optional for SID devices, where the entries can be used to add properties into self-identifying device nodes. See sbus(4) and pci(4).
