Yes, but I want to leave my hard disk in the bus1 location and still
boot from it.  My bios can do this.

You were correct above with disk=/dev/hdb bios=0x80.

There was one additional thing which I couldn't figure out for ages.  I
also needed this
linear  (I did have lba32 instead).  When I put lba32 it doesn't work.
When I put linear it does work.  Strange, because on the first HD
/etc/lilo.conf I have it the other way around.  Very Confusing!

So here is what I have in /etc/lilo.conf for the second HD - which works!
-------------------------------------------------
linear
disk=/dev/ide/host0/bus1/target0/lun0/disc
bios=0x80
boot=/dev/ide/host0/bus1/target0/lun0/disc
root=/dev/ide/host0/bus1/target0/lun0/part5
install=/boot/boot.b
map=/boot/map
delay=20
vga=normal
default=Linux
image=/vmlinuz
        label=Linux
        read-only

image=/vmlinuz.old
        label=LinuxOLD
        read-only
        optional
-------------------------------------------------

I still don't understand a few things though.  Why do I need linear?
Why do I need bios=0x80 when it is really 0x82 (I think)?

Thanks again for helping me out.  It finally works :-)
Mark.
