I have tried all combinations of flags, to no avail. Also, I have tried two parallel port BIOS settings: "normal" and "EPP". I don't know whether the BIOS settings are important or not. I am not a parallel port guru! :-) In all cases, the vpo controller is initialized at boot (given that the ZIP drive is on and attached), but the "da" device is not initialized. Perhaps the problem resides in the interaction between CAM (scbus/da) and the vpo controller. BTW, when booting verbosely, the ppc driver is very little verbose! I have examined ppc.c and it is plenty of "if (bootverbose) ..."; however, all these "printf"s do not show while booting. -- JMA ----------------------------------------------------------------------- José Mª Alcaide | mailto:jose@we.lc.ehu.es Universidad del País Vasco | http://www.we.lc.ehu.es/~jose Dpto. de Electricidad y Electrónica | Facultad de Ciencias - Campus de Lejona | Tel.: +34-946012479 48940 Lejona (Vizcaya) - SPAIN | Fax: +34-944858139 ----------------------------------------------------------------------- "Go ahead... make my day." - H.
