I think this is > strange. You cannot establish a boot device in the config file, all you can do there is specifying the *default* root device. Note that this will almost always be overridden at boot time by the actual device you have been booting from. Sysinstall doesn't support installation on floppies at all. > - How could I manually install the kernel on a floppy? disklabel -Brw fd0 fd1440 newfs -t0 -u0 -l1 -i65536 /dev/rfd0 mount /dev/fd0 /mnt cp /kernel /mnt umount /mnt > - What commands are necessary to create a boot- and a root floppy? The boot floppy is above. The root floppy is initially basically the same, but you don't copy a kernel over to it. Instead, you create a regular file system, with the following minimal files on it: /bin/sh /sbin/init /dev/console plus everything else you'd like to see there. ``Crunching'' the binary is highly recommended. RTFM crunchgen(1) for this, and see also the files under /usr/src/release/. > I think there should be a FAQ or howto for this, or doesn't anyone else need > an emergency backup routine? The provided fixit floppy is probably working well enough for most folks. Boot the installation floppy, select ``F)ixit'', and put the fixit floppy in. Note that this scenario is a little different from the ``classic'' boot/root floppy pair i've described above. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
