Not exactly what I'm after. It's okay for the LILO setup to point to things on the hard drive, but I want at least one kernel on the floppy. This is what saves me when I've deleted a partition, so that the partition numbers are all messed up, or worse yet have moved a partition so there's no kernel where the floppy thinks it should be. I do this a lot. It used to be handy: the floppy was it's own self-contained universe, and the running system would visit it briefly to re-run LILO in the chroot jail, so that the /etc/lilo.conf file could refer to things where they were in relation to the floppy. This worked on all Caldera systems where I tried it (from way back on CND). I don't remember if I've tried this on RedHat before. It's not too hard to build a secondary lilo.conf, which points to /dev/fd0, and knows about a kernel on /mnt/floppy, but it doesn't have the same feel to it. Sigh. I'll get over it. ++ kevin -- Kevin O'Gorman (805) 650-6274 mailto:[EMAIL PROTECTED] Permanent e-mail forwarder: mailto:Kevin.O'[EMAIL PROTECTED] At school: mailto:[EMAIL PROTECTED] Web: http://www.cs.ucsb.edu/~kogorman/index.html Web: http://kosmanor.com/~kevin/index.html "Life is short; eat dessert first!" _______________________________________________ Linux-users mailing list - http://linux-sxs.org/mailman/listinfo/linux-users Subscribe/Unsubscribe info, Archives,and Digests are located at the above URL.
