creating bootable solid state disks

What is the simplest way to build a bootable system onto a
newly formatted solid state disk on a different device than
the one the system was booted from?
Say I have just built my kernel under a plain RedHat distro
on /dev/hda and want to make a bootable Disk On Module temporarily
connected on any different atapi port (say /dev/hdc).
The destination disk was already partitioned and formatted and
basic system files and directories were also copied.
Once created the disk will be moved and booted again as the
first primary (hda).
I've tried multiple times different lilo configurations,
but never managed to boot the destination disk. The Linux
From Scratch manual didn't help much.

Any info will be appreciated. Tankyou.
