If I type '?' to that, it says "List of GEOM managed disk > devices:", but it shows no devices in that list. I re-built last night and the eMac hangs in the ATA probe, so you're a little better off than I am :) Working on it as we speak. > Is there any simple way for me to get back to the kernel which had > been working for me? When booting the loader from the OpenFirmware prompt, give it a partition which is either non-existent, doesn't have a kernel to load, or isn't a UFS partition e.g. 0 > boot hd:loader hd:0 ... / can't load kernel Type '?' for a list of commands, 'help' for more detailed help. OK _ At this point, you can set currdev and manually load a kernel e.g. OK set currdev=hd:14 OK load /boot/kernel/kernel.save and then OK boot later, Peter.
