As you pointed out, the Startup Disk control panels will change the boot device (overwriting that variable in OF), but simply booting OS X (or OS9) won't change it. (And it's all but trivial to boot manually into linux to re-run ybin.) Dual-boot may be more challenging with an OldWorld Mac, but IIRC there were few if any OldWorld G3s. --keith -- kkeller@xxxxxxxxxxxxx
