Thanks for the help everyone..I ended up following this guide... but confusing myself because the drive was still only showing 4gb rather than the full 8gb. I managed to put classicWB on the card and booted it up and it saw the full 8gb... This must've been one of the most difficult/frustrating tasks ever!
Not helped by there seemingly multiple ways of achieving the end result..conflicting guyides..old/outdated advice etc etc
Anyway its done now and I have a 8gb CF card with whdload and all the useful tools that I found during this exercise...
The guide I used, in case anyone else gets as frustrated as I did...
