Looking for help getting netbsd running on Jornada 690

I recently bought a hp Jornada 690 for around $60 shortly after learning 
I could run NetBSD on it.
I have read many old guides to get NetBSD running on this device, But I 
keep getting confused and getting nowhere.
I have a cf reader and another computer running Ubuntu that I have been 
using to get files onto the Jornada.

Can someone tell me how to get NetBSD running on this Jornada or link me 
to a guide on the topic?

Thanks
