No, but I answered the question as posed. I would guess that lilo
just modifies the same bytes as rdev does, but on the fly as it loads
the kernel.

I think that may change everything. Allowing for typos, because you
copied that off the screen, did it really say FAT 12? It looks as
though it's either misread the partition table (perhaps it got the
geometry wrong or something) or the kernel lacks some necessary
functionality to handle the new disk. What does lsmod show when you
have the disk on /mnt. Is it using a module to get at that disk?
Could your partitions be misnumbered in some way?
Either way, I think you may need more expert help than I can provide.
Cheers,
