Install and Boot Ubuntu from a Compact Flash card

I have been trying to install Ubuntu 8.04 LTS on a Compact Flash card and boot from it. At first, I thought the whole exercise would be straightforward. The hardware I use is a Jetway Mini-ITX J7F2 board connected with a daughter board AD3RTLAN-G which provides 3 extra Gigabits ethernet ports. The chassis is a LinITX M200 with a 20 x 2 USB LCD front panel, 2 x USB ports and a CF reader which connects to the IDE bus and a pico power supply. Here is a photo of it.
