There's a hint in LFS "boot any hd" that sounds like it might give you
some needed information. Essentially, the critical pieces in there for
you should be the "bios=" parameters which will allow you to set up your
second HD to boot while you are running from either one.

Once you've booted on that second disk, modify the lilo.conf to now
expect your 2nd drive as the first, run lilo and then reboot.

As always, when playing with boot stuff *be sure* you have a rescue
floppy of some kind handy. Also, use dd to save your boot block (if it's
not too late already) somewhere you can get it again, in case you blow
it big-time.

If the hint doesn't get you going, post again with more details and I'll
try and help out. But, *warning*, I can get quite cranky if you don't
first try to read and understand and carefully think. I have other
things that have my interest ATM.

No apology necessary: we are quite "international" here.  :)
