I've never seen this, but I'm the lilo enthusiast on the editorial
team, so I'd better respond ;) Let's try to work this out.
The message you are getting seems to come from mbr.S in lilo, and
is produced becasue it cannot find the 'LILO' text at offset 6 in
the potential mbr it is looking at. On my machine booting on
/dev/sda the start of the mbr looks like this:
[EMAIL PROTECTED] /home/ken/lilo-22.7.1 #hexdump -C -n 512 /dev/sda
00000000 fa eb 21 01 b2 01 4c 49 4c 4f 16 07 44 63 77 44
|..!...LILO..DcwD|
You seem to have started to boot from lilo (otherwise, it could not
produce the error message), so maybe it is looking in the wrong
place. I'm not clear about your setup -
(1.) which partition contains the host system ?
(2.) can you still boot the host system ? (Actually, if you can't,
trying to fix it will be an interesting exercise).
(3.) but most importantly, what is in your lilo.conf ?
In particular, where does 'boot=' point to ?
I've never tried booting from other than the first hard disk, but
I can recall that people used to have to do things when upgrading a
disk (install on the slave, then pull out the original disk and make
the new one the master) - in that case, people had to use
disk=/dev/hdb bios=0x80 # Tell LILO to treat the second
# disk as if it were the first
# disk (BIOS ID 0x80).
boot=/dev/hdb # Install LILO on second hard
# disk.
(taken from www.tldp.org/HOWTO/Hard-Disk-Upgrade/prepare.html)
I'm not clear if you have a first disk (sda) connected ?
