Writing Device Drivers

Bootable (Realmode) Drivers

A separate realmode driver might need to be developed for the booting system. See the Realmode Drivers white paper in the Driver Development Site at http://soldc.sun.com/developer/support/driver for information on realmode drivers. Hardware configuration files may be needed on some occasions to augment the information provided by the booting system. See driver.conf(4) and isa(4) for further details.
