Absolutely, yes. We _might_ want to hack isolinux to run the 64-bit kernel if it can. >M68k (amiga) uses icons on the CD and can be added too. Yup. >Alpha hacks into the first block on the CD (aboot) and uses milo >otherwise. Not sure if aboot interferes with isolinux, I didn't need >it. I've been playing with this lot for the JTE work. Several arches write boot information into sector 0, several into sector 16, but not all: alpha: write pointers into sector 0 arm: need no special boot sector, the bootloader is often intelligent enough to cope amd64: El Torito, same as i386 (pointers in sector 16) hppa: write pointers into sector 0 i386: El Torito (sector 16) ia64: El Torito (sector 16) m68k: varies; amiga needs no special boot sector, bvme* uses El Torito (sector 16) mips: write pointers into sector 0 mipsel: write pointers into sector 0 ppc: not 100% sure ( anyone? ) s390: not bootable from CD sparc: not 100% sure ( anyone? ) We _might_ be able to get away with overloading sector(s) 0 and 16 in some cases, but that will be difficult. >A while back I mixed myself an universal rescue CD for those three >and that came in handy a few times.

Maybe. I'm thinking of a cool hack here, though... :-) -- Steve McIntyre, Cambridge, UK.
