hi ya hans
hummm... i do the simple dumb way....
# vi /etc/lilo.conf
# change the boot option
#
# boot=/dev/hda
boot=/dev/fd0
#
...
# lilo
and reset it back to hda and rerun lilo for good measure
that lilo'd floppy sometimes boots..sometimes not.. seems
to be hardware dependent ?? ( didnt go figure out why it fails )
if it does fail... as was said earlier
dd if=/boot/vmlinuz-2.xxxx of=/dev/fdo bs=1024
rdev /dev/fd0 /dev/hda1 (or wherever / is located )
if you use mkbootdisk .. you need to replace that kernel w/ the new one
if you use syslinux .... you need a dos-formated floppy...
- avoids lilo headaches
if you use grub.... i havent played with it yet..
c ya
