Hi Sven, I recently noted a post stating that the bootloader development team did not have access to an oldword powerpc. I have one of those, and can do some testing this weekend, even if it renders my openfirmware settings obsolete.
I'm afraid I'm not an expert, but I got some real great help on this list earlier, and am eager to do something in return. So just mail me privately if there is any testing I can do (I've got a 6500 with internal + external monitor card, internal IDE disk + 2 external SCSI disks. I'm afraid I don't get a OpenFirmware prompt though, but I can read it with the BootVars program or nvsetenv). Regards, Freek Dijkstra
