Backupimage WM5

Hi there! 

i've installed familiar and opie on my hp hx4700 months ago, and worked
with it. sometimes i liked it, sometimes i hate it, really. can't use
wpa, and the most hardly part: no good media support...

now i want to "downgrade" back to windows, but i can't find my backup
image. 

can anyone of you help me, please? maybe one of you have a dd image
ready for me...

thank you very much!
