It seems kinda uncool to reply to my own thread, but I'm really at wit's
end. Google found 237 ref's to this (mine led the list) with, at least
through the first 40, pretty lame help.
I can boot to kernel 2.2.17 ok, by rescue floppy or lilo choice. Any
try at kernel 2.4.17-686, with 'root=' at prompt, or in lilo.conf, or
the append statement within lilo.conf yields the above error message.
/vmlinuz and /vmlinuz.old point appropriately into /boot.
/initrd.img points to /boot/initrd.img-2.4.17-686.
/initrd/ is empty.
Attached is my lilo.conf file. I know this must have some simple-minded
fix; I just don't have a clue.
tnx,
