i don't think it even needs to be that way either. you can do one of two things: make the rescue disk use msdos filesystem instead of ext2, and put a .coff format kernel on it. this would be bootable with the OpenFirmware command: boot fd:,linux or something similar (the device name may vary) the disadvantage to this is you must enter OF somehow, this usually requires a serial terminal. the other option is make the rescue image use hfs filesystem, there is nothing about miboot that requires a layout any different then the regular rescue image has (well if there is it could be fixed except for needing macos to compile miboot...). miboot would be analogous to syslinux in this case. dbootstrap would have to be tought how to mount hfs rescue images in addition to msdos and ext2, but that shoudn't be that difficult. i don't think its possible to make a generic rescue image that will boot all the various powerpcs, but isn't there several different versions of it anyway for the different powerpc sub-archs? > Wouldn't it be easier to just get the kernel directly from one of the > 'linux' files lying around, in the case that the user is installing by > a method other than floppies? This might be an easy, general fix we > can do for all arches. if all thats being grabbed from rescue.bin that makes sense. -- Ethan Benson http://www.alaska.net/~erbenson/
