Is this still true? No; it's quite possible now to boot from beyond the 1024 cylinder mark, however boot0 does not install in 'packet' mode by default, which means that you need to manually install/configure it before rebooting after system installation. So we don't cleanly install for > 1024 cylinders, but it works with a little tweaking. -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also.
