Just change kernel options? Yes, that's it. At this time, the following 4 lines can be added to achieve the switch: nooption GEOM_BSD nooption GEOM_MBR options GEOM_PART_BSD options GEOM_PART_MBR > > Also, while here, the APM (apple partition manager) module doesn't > quite work with Tivo disks.

Do you know if there's anything we can check for in case there's no DDR? I'm thinking of accepting a DDR-less APM scheme only if we find some indication that it's a Tivo disk. I guess I like the comfort of checking the DDR and prefer not to eliminate it unconditionally. This may not be possible though... -- Marcel Moolenaar xcllnt@mac.com
